• Follow the citation style guidelines: Different disciplines and journals may require different citation styles (e.g., APA, MLA, Chicago). It is important to follow the specific guidelines for the citation style required.
• Include all necessary information : Each citation should include enough information for readers to locate the source. For example, a journal article citation should include the author(s), title of the article, journal title, volume number, issue number, page numbers, and publication year.
• Use proper formatting: Citation styles typically have specific formatting requirements for different types of sources. Make sure to follow the proper formatting for each citation.
• Order citations alphabetically: If listing multiple sources, they should be listed alphabetically by the author’s last name.
• Be consistent: Use the same citation style throughout the entire paper or project.
• Check for accuracy: Double-check all citations to ensure accuracy, including correct spelling of author names and publication information.
• Use reputable sources: When selecting sources to cite, choose reputable and authoritative sources. Avoid sources that are biased or unreliable.
• Include all sources: Make sure to include all sources used in the research, including those that were not directly quoted but still informed the work.
• Use online tools : There are online tools available (e.g., citation generators) that can help with formatting and organizing references.

Purpose of References in Research

References in research serve several purposes:

• To give credit to the original authors or sources of information used in the research. It is important to acknowledge the work of others and avoid plagiarism.
• To provide evidence for the claims made in the research. References can support the arguments, hypotheses, or conclusions presented in the research by citing relevant studies, data, or theories.
• To allow readers to find and verify the sources used in the research. References provide the necessary information for readers to locate and access the sources cited in the research, which allows them to evaluate the quality and reliability of the information presented.
• To situate the research within the broader context of the field. References can show how the research builds on or contributes to the existing body of knowledge, and can help readers to identify gaps in the literature that the research seeks to address.

Importance of References in Research

References play an important role in research for several reasons:

• Credibility : By citing authoritative sources, references lend credibility to the research and its claims. They provide evidence that the research is based on a sound foundation of knowledge and has been carefully researched.
• Avoidance of Plagiarism : References help researchers avoid plagiarism by giving credit to the original authors or sources of information. This is important for ethical reasons and also to avoid legal repercussions.
• Reproducibility : References allow others to reproduce the research by providing detailed information on the sources used. This is important for verification of the research and for others to build on the work.
• Context : References provide context for the research by situating it within the broader body of knowledge in the field. They help researchers to understand where their work fits in and how it builds on or contributes to existing knowledge.
• Evaluation : References provide a means for others to evaluate the research by allowing them to assess the quality and reliability of the sources used.

Advantages of References in Research

There are several advantages of including references in research:

• Acknowledgment of Sources: Including references gives credit to the authors or sources of information used in the research. This is important to acknowledge the original work and avoid plagiarism.
• Evidence and Support : References can provide evidence to support the arguments, hypotheses, or conclusions presented in the research. This can add credibility and strength to the research.
• Reproducibility : References provide the necessary information for others to reproduce the research. This is important for the verification of the research and for others to build on the work.
• Context : References can help to situate the research within the broader body of knowledge in the field. This helps researchers to understand where their work fits in and how it builds on or contributes to existing knowledge.
• Evaluation : Including references allows others to evaluate the research by providing a means to assess the quality and reliability of the sources used.
• Ongoing Conversation: References allow researchers to engage in ongoing conversations and debates within their fields. They can show how the research builds on or contributes to the existing body of knowledge.

Reference List: Common Reference List Examples

Article (with doi).

Alvarez, E., & Tippins, S. (2019). Socialization agents that Puerto Rican college students use to make financial decisions. Journal of Social Change , 11 (1), 75–85. https://doi.org/10.5590/JOSC.2019.11.1.07

Laplante, J. P., & Nolin, C. (2014). Consultas and socially responsible investing in Guatemala: A case study examining Maya perspectives on the Indigenous right to free, prior, and informed consent. Society & Natural Resources , 27 , 231–248. https://doi.org/10.1080/08941920.2013.861554

Use the DOI number for the source whenever one is available. DOI stands for "digital object identifier," a number specific to the article that can help others locate the source. In APA 7, format the DOI as a web address. Active hyperlinks for DOIs and URLs should be used for documents meant for screen reading. Present these hyperlinks in blue and underlined text (the default formatting in Microsoft Word), although plain black text is also acceptable. Be consistent in your formatting choice for DOIs and URLs throughout your reference list. Also see our Quick Answer FAQ, "Can I use the DOI format provided by library databases?"

Jerrentrup, A., Mueller, T., Glowalla, U., Herder, M., Henrichs, N., Neubauer, A., & Schaefer, J. R. (2018). Teaching medicine with the help of “Dr. House.” PLoS ONE , 13 (3), Article e0193972. https://doi.org/10.1371/journal.pone.0193972

For journal articles that are assigned article numbers rather than page ranges, include the article number in place of the page range.

For more on citing electronic resources, see  Electronic Sources References .

Article (Without DOI)

Found in a common academic research database or in print.

Casler , T. (2020). Improving the graduate nursing experience through support on a social media platform. MEDSURG Nursing , 29 (2), 83–87.

If an article does not have a DOI and you retrieved it from a common academic research database through the university library, there is no need to include any additional electronic retrieval information. The reference list entry looks like the entry for a print copy of the article. (This format differs from APA 6 guidelines that recommended including the URL of a journal's homepage when the DOI was not available.) Note that APA 7 has additional guidance on reference list entries for articles found only in specific databases or archives such as Cochrane Database of Systematic Reviews, UpToDate, ProQuest Dissertations and Theses Global, and university archives. See APA 7, Section 9.30 for more information.

Found on an Open Access Website

Eaton, T. V., & Akers, M. D. (2007). Whistleblowing and good governance. CPA Journal , 77 (6), 66–71. http://archives.cpajournal.com/2007/607/essentials/p58.htm

Provide the direct web address/URL to a journal article found on the open web, often on an open access journal's website. In APA 7, active hyperlinks for DOIs and URLs should be used for documents meant for screen reading. Present these hyperlinks in blue and underlined text (the default formatting in Microsoft Word), although plain black text is also acceptable. Be consistent in your formatting choice for DOIs and URLs throughout your reference list.

Weinstein, J. A. (2010).  Social change  (3rd ed.). Rowman & Littlefield.

If the book has an edition number, include it in parentheses after the title of the book. If the book does not list any edition information, do not include an edition number. The edition number is not italicized.

American Nurses Association. (2015). Nursing: Scope and standards of practice (3rd ed.).

If the author and publisher are the same, only include the author in its regular place and omit the publisher.

Lencioni, P. (2012). The advantage: Why organizational health trumps everything else in business . Jossey-Bass. https://amzn.to/343XPSJ

As a change from APA 6 to APA 7, it is no longer necessary to include the ebook format in the title. However, if you listened to an audiobook and the content differs from the text version (e.g., abridged content) or your discussion highlights elements of the audiobook (e.g., narrator's performance), then note that it is an audiobook in the title element in brackets. For ebooks and online audiobooks, also include the DOI number (if available) or nondatabase URL but leave out the electronic retrieval element if the ebook was found in a common academic research database, as with journal articles. APA 7 allows for the shortening of long DOIs and URLs, as shown in this example. See APA 7, Section 9.36 for more information.

Chapter in an Edited Book

Poe, M. (2017). Reframing race in teaching writing across the curriculum. In F. Condon & V. A. Young (Eds.), Performing antiracist pedagogy in rhetoric, writing, and communication (pp. 87–105). University Press of Colorado.

Include the page numbers of the chapter in parentheses after the book title.

Christensen, L. (2001). For my people: Celebrating community through poetry. In B. Bigelow, B. Harvey, S. Karp, & L. Miller (Eds.), Rethinking our classrooms: Teaching for equity and justice (Vol. 2, pp. 16–17). Rethinking Schools.

Also include the volume number or edition number in the parenthetical information after the book title when relevant.

Freud, S. (1961). The ego and the id. In J. Strachey (Ed.),  The standard edition of the complete psychological works of Sigmund Freud  (Vol. 19, pp. 3-66). Hogarth Press. (Original work published 1923)

When a text has been republished as part of an anthology collection, after the author’s name include the date of the version that was read. At the end of the entry, place the date of the original publication inside parenthesis along with the note “original work published.” For in-text citations of republished work, use both dates in the parenthetical citation, original date first with a slash separating the years, as in this example: Freud (1923/1961). For more information on reprinted or republished works, see APA 7, Sections 9.40-9.41.

Classroom Resources

Citing classroom resources.

If you need to cite content found in your online classroom, use the author (if there is one listed), the year of publication (if available), the title of the document, and the main URL of Walden classrooms. For example, you are citing study notes titled "Health Effects of Exposure to Forest Fires," but you do not know the author's name, your reference entry will look like this:

Health effects of exposure to forest fires [Lecture notes]. (2005). Walden University Canvas. https://waldenu.instructure.com

If you do know the author of the document, your reference will look like this:

Smith, A. (2005). Health effects of exposure to forest fires [PowerPoint slides]. Walden University Canvas. https://waldenu.instructure.com  

A few notes on citing course materials:

• [Lecture notes]
• [Course handout]
• [Study notes]
• It can be difficult to determine authorship of classroom documents. If an author is listed on the document, use that. If the resource is clearly a product of Walden (such as the course-based videos), use Walden University as the author. If you are unsure or if no author is indicated, place the title in the author spot, as above.
• If you cannot determine a date of publication, you can use n.d. (for "no date") in place of the year.

Note:  The web location for Walden course materials is not directly retrievable without a password, and therefore, following APA guidelines, use the main URL for the class sites: https://class.waldenu.edu.

Citing Tempo Classroom Resources

Clear author: 

Smith, A. (2005). Health effects of exposure to forest fires [PowerPoint slides]. Walden University Brightspace. https://mytempo.waldenu.edu

Dictionary Entry

Merriam-Webster. (n.d.). Leadership. In Merriam-Webster.com dictionary . Retrieved May 28, 2020, from https://www.merriam-webster.com/dictionary/leadership

When constructing a reference for an entry in a dictionary or other reference work that has no byline (i.e., no named individual authors), use the name of the group—the institution, company, or organization—as author (e.g., Merriam Webster, American Psychological Association, etc.). The name of the entry goes in the title position, followed by "In" and the italicized name of the reference work (e.g., Merriam-Webster.com dictionary , APA dictionary of psychology ). In this instance, APA 7 recommends including a retrieval date as well for this online source since the contents of the page change over time. End the reference entry with the specific URL for the defined word.

Baker, A. (2014, May 7). Connecticut students show gains in national tests. New York Times . http://www.nytimes.com/2014/05/08/nyregion/national-assessment-of-educational-progress-results-in-Connecticut-and-New-Jersey.html

Include the full date in the format Year, Month Day. Do not include a retrieval date for periodical sources found on websites. Note that for citations, include only the year: Baker (2014). For newspaper articles retrieved from a common academic research database, leave out the URL. For newspaper articles from an online news website that is not an online version of a print newspaper, follow the format for a webpage reference list entry.

OASIS Resources

Oasis webpage.

OASIS. (n.d.). Common reference list examples . Walden University. https://academicguides.waldenu.edu/writingcenter/apa/references/examples

For all OASIS content, list OASIS as the author. Because OASIS webpages do not include publication dates, use “n.d.” for the year.

Interactive Guide

OASIS. (n.d.). Embrace iterative research and writing [Interactive guide]. Walden University. https://academics.waldenu.edu/oasis/iterative-research-writing-web

For OASIS multimedia resources, such as interactive guides, include a description of the resource in brackets after the title.

Online Video/Webcast

Walden University. (2013).  An overview of learning  [Video]. Walden University Canvas.  https://waldenu.instructure.com  

Use this format for online videos such as Walden videos in classrooms. Most of our classroom videos are produced by Walden University, which will be listed as the author in your reference and citation. Note: Some examples of audiovisual materials in the APA manual show the word “Producer” in parentheses after the producer/author area. In consultation with the editors of the APA manual, we have determined that parenthetical is not necessary for the videos in our courses. The manual itself is unclear on the matter, however, so either approach should be accepted. Note that the speaker in the video does not appear in the reference list entry, but you may want to mention that person in your text. For instance, if you are viewing a video where Tobias Ball is the speaker, you might write the following: Tobias Ball stated that APA guidelines ensure a consistent presentation of information in student papers (Walden University, 2013). For more information on citing the speaker in a video, see our page on Common Citation Errors .

Taylor, R. [taylorphd07]. (2014, February 27). Scales of measurement [Video]. YouTube. https://www.youtube.com/watch?v=PDsMUlexaMY

OASIS. (2020, April 15). One-way ANCOVA: Introduction [Video]. YouTube. https://youtu.be/_XnNDQ5CNW8

For videos from streaming sites, use the person or organization who uploaded the video in the author space to ensure retrievability, whether or not that person is the speaker in the video. A username can be provided in square brackets. As a change from APA 6 to APA 7, include the publisher after the title, and do not use "Retrieved from" before the URL. See APA 7, Section 10.12 for more information and examples.

See also reference list entry formats for TED Talks .

Technical and Research Reports

Edwards, C. (2015). Lighting levels for isolated intersections: Leading to safety improvements (Report No. MnDOT 2015-05). Center for Transportation Studies. http://www.cts.umn.edu/Publications/ResearchReports/reportdetail.html?id=2402

Technical and research reports by governmental agencies and other research institutions usually follow a different publication process than scholarly, peer-reviewed journals. However, they present original research and are often useful for research papers. Sometimes, researchers refer to these types of reports as gray literature , and white papers are a type of this literature. See APA 7, Section 10.4 for more information.

Reference list entires for TED Talks follow the usual guidelines for multimedia content found online. There are two common places to find TED talks online, with slightly different reference list entry formats for each.

TED Talk on the TED website

If you find the TED Talk on the TED website, follow the format for an online video on an organizational website:

Owusu-Kesse, K. (2020, June). 5 needs that any COVID-19 response should meet [Video]. TED Conferences. https://www.ted.com/talks/kwame_owusu_kesse_5_needs_that_any_covid_19_response_should_meet

The speaker is the author in the reference list entry if the video is posted on the TED website. For citations, use the speaker's surname.

TED Talk on YouTube

If you find the TED Talk on YouTube or another streaming video website, follow the usual format for streaming video sites:

TED. (2021, February 5). The shadow pandemic of domestic violence during COVID-19 | Kemi DaSilvalbru [Video]. YouTube. https://www.youtube.com/watch?v=PGdID_ICFII

TED is the author in the reference list entry if the video is posted on YouTube since it is the channel on which the video is posted. For citations, use TED as the author.

Walden University Course Catalog

To include the Walden course catalog in your reference list, use this format:

Walden University. (2020). 2019-2020 Walden University catalog . https://catalog.waldenu.edu/index.php

If you cite from a specific portion of the catalog in your paper, indicate the appropriate section and paragraph number in your text:

...which reflects the commitment to social change expressed in Walden University's mission statement (Walden University, 2020, Vision, Mission, and Goals section, para. 2).

And in the reference list:

Walden University. (2020). Vision, mission, and goals. In 2019-2020 Walden University catalog. https://catalog.waldenu.edu/content.php?catoid=172&navoid=59420&hl=vision&returnto=search

Vartan, S. (2018, January 30). Why vacations matter for your health . CNN. https://www.cnn.com/travel/article/why-vacations-matter/index.html

For webpages on the open web, include the author, date, webpage title, organization/site name, and URL. (There is a slight variation for online versions of print newspapers or magazines. For those sources, follow the models in the previous sections of this page.)

American Federation of Teachers. (n.d.). Community schools . http://www.aft.org/issues/schoolreform/commschools/index.cfm

If there is no specified author, then use the organization’s name as the author. In such a case, there is no need to repeat the organization's name after the title.

In APA 7, active hyperlinks for DOIs and URLs should be used for documents meant for screen reading. Present these hyperlinks in blue and underlined text (the default formatting in Microsoft Word), although plain black text is also acceptable. Be consistent in your formatting choice for DOIs and URLs throughout your reference list.

Quick Rules for an APA Reference List

Your research paper ends with a list of all the sources cited in your paper. Here are some quick rules for this Reference list:

• Begin the reference list on a new page after the text.
• Name it "References," and center the section label in bold at the top of the page.
• Order the reference list alphabetically by author (last name of the first author followed by the initials of the author's given name(s)).
• Alphabetize entries by authors who have the same given name and last name with suffixes indicating birth order chronologically, oldest first.
• Double-space the entire list (both within and between entries).
• Apply a hanging indent of 0.5 in. to each entry. This means that the first line of the reference is flush left and subsequent lines are indented 0.5 in. from the left margin.

Sample Paper with Reference List

The American Psychological Association (APA) has created  a sample paper  that includes explanations of the elements and formatting in APA 7th ed.

Basic Principles of Citation

APA Style uses the author–date citation system , in which a brief in-text citation directs readers to a full reference list entry. The in-text citation appears within the body of the paper (or in a table, figure, footnote, or appendix) and briefly identifies the cited work by its author and date of publication. This enables readers to locate the corresponding entry in the alphabetical reference list at the end of the paper.

Each work cited must appear in the reference list, and each work in the reference list must be cited in the text (or in a table, figure, footnote, or appendix).

Both paraphrases and quotations require citations.

The following are guidelines to follow when writing in-text citations:

• Ensure that the spelling of author names and the publication dates in reference list entries match those in the corresponding in-text citations.
• Cite only works that you have read and ideas that you have incorporated into your writing. The works you cite may provide key background information, support or dispute your thesis, or offer critical definitions and data.
• Readers may find a long string of citations difficult to understand, especially if they are using assistive technology such as a screen reader; therefore, include only those citations needed to support your immediate point.
• Cite primary sources when possible, and cite secondary sources sparingly.
• Cite sources to document all facts and figures that you mention that are not common knowledge.
• To cite a specific part of a source , provide an author–date citation for the work plus information about the specific part.
• Even when sources cannot be retrieved (e.g., because they are personal communications ), still credit them in the text (however, avoid using online sources that are no longer recoverable).

Basic principles of citation are covered in the seventh edition APA Style manuals in the Publication Manual Sections 8.1 to 8.36 and the Concise Guide Sections 8.1 to 8.34

5107 Accesses

When we write an essay, research paper, thesis, or book, it is normal to include information from the work of others or support our arguments by reference to other published works. All such academic documents draw heavily on the ideas and findings of previous and current researchers available through various sources such as books, journals, theses, newspapers, magazines, government reports, or Internet sources. In all these cases, proper referencing is essential in order to ensure easy retrieval of information. Referencing is the name given to the method of showing and acknowledging the sources from which the author has obtained ideas or information.

Everything deep is also simple and can be reproduced simply as long as its reference to the whole truth is maintained. But what matters is not what is witty but what is true. Albert Schweitzer (1875–1965)

How to Cite Sources

Here is a complete list for how to cite sources. Most of these guides present citation guidance and examples in MLA, APA, and Chicago.

If you’re looking for general information on MLA or APA citations , the EasyBib Writing Center was designed for you! It has articles on what’s needed in an MLA in-text citation , how to format an APA paper, what an MLA annotated bibliography is, making an MLA works cited page, and much more!

MLA Format Citation Examples

The Modern Language Association created the MLA Style, currently in its 9th edition, to provide researchers with guidelines for writing and documenting scholarly borrowings.  Most often used in the humanities, MLA style (or MLA format ) has been adopted and used by numerous other disciplines, in multiple parts of the world.

MLA provides standard rules to follow so that most research papers are formatted in a similar manner. This makes it easier for readers to comprehend the information. The MLA in-text citation guidelines, MLA works cited standards, and MLA annotated bibliography instructions provide scholars with the information they need to properly cite sources in their research papers, articles, and assignments.

APA Format Citation Examples

The American Psychological Association created the APA citation style in 1929 as a way to help psychologists, anthropologists, and even business managers establish one common way to cite sources and present content.

APA is used when citing sources for academic articles such as journals, and is intended to help readers better comprehend content, and to avoid language bias wherever possible. The APA style (or APA format ) is now in its 7th edition, and provides citation style guides for virtually any type of resource.

Chicago Style Citation Examples

The Chicago/Turabian style of citing sources is generally used when citing sources for humanities papers, and is best known for its requirement that writers place bibliographic citations at the bottom of a page (in Chicago-format footnotes ) or at the end of a paper (endnotes).

The Turabian and Chicago citation styles are almost identical, but the Turabian style is geared towards student published papers such as theses and dissertations, while the Chicago style provides guidelines for all types of publications. This is why you’ll commonly see Chicago style and Turabian style presented together. The Chicago Manual of Style is currently in its 17th edition, and Turabian’s A Manual for Writers of Research Papers, Theses, and Dissertations is in its 8th edition.

6 Interesting Citation Facts

The world of citations may seem cut and dry, but there’s more to them than just specific capitalization rules, MLA in-text citations , and other formatting specifications. Citations have been helping researches document their sources for hundreds of years, and are a great way to learn more about a particular subject area.

Ever wonder what sets all the different styles apart, or how they came to be in the first place? Read on for some interesting facts about citations!

1. There are Over 7,000 Different Citation Styles

You may be familiar with MLA and APA citation styles, but there are actually thousands of citation styles used for all different academic disciplines all across the world. Deciding which one to use can be difficult, so be sure to ask you instructor which one you should be using for your next paper.

2. Some Citation Styles are Named After People

While a majority of citation styles are named for the specific organizations that publish them (i.e. APA is published by the American Psychological Association, and MLA format is named for the Modern Language Association), some are actually named after individuals. The most well-known example of this is perhaps Turabian style, named for Kate L. Turabian, an American educator and writer. She developed this style as a condensed version of the Chicago Manual of Style in order to present a more concise set of rules to students.

3. There are Some Really Specific and Uniquely Named Citation Styles

How specific can citation styles get? The answer is very. For example, the “Flavour and Fragrance Journal” style is based on a bimonthly, peer-reviewed scientific journal published since 1985 by John Wiley & Sons. It publishes original research articles, reviews and special reports on all aspects of flavor and fragrance. Another example is “Nordic Pulp and Paper Research,” a style used by an international scientific magazine covering science and technology for the areas of wood or bio-mass constituents.

4. More citations were created on  EasyBib.com  in the first quarter of 2018 than there are people in California.

The US Census Bureau estimates that approximately 39.5 million people live in the state of California. Meanwhile, about 43 million citations were made on EasyBib from January to March of 2018. That’s a lot of citations.

5. “Citations” is a Word With a Long History

The word “citations” can be traced back literally thousands of years to the Latin word “citare” meaning “to summon, urge, call; put in sudden motion, call forward; rouse, excite.” The word then took on its more modern meaning and relevance to writing papers in the 1600s, where it became known as the “act of citing or quoting a passage from a book, etc.”

6. Citation Styles are Always Changing

The concept of citations always stays the same. It is a means of preventing plagiarism and demonstrating where you relied on outside sources. The specific style rules, however, can and do change regularly. For example, in 2018 alone, 46 new citation styles were introduced , and 106 updates were made to exiting styles. At EasyBib, we are always on the lookout for ways to improve our styles and opportunities to add new ones to our list.

Why Citations Matter

Here are the ways accurate citations can help your students achieve academic success, and how you can answer the dreaded question, “why should I cite my sources?”

They Give Credit to the Right People

Citing their sources makes sure that the reader can differentiate the student’s original thoughts from those of other researchers. Not only does this make sure that the sources they use receive proper credit for their work, it ensures that the student receives deserved recognition for their unique contributions to the topic. Whether the student is citing in MLA format , APA format , or any other style, citations serve as a natural way to place a student’s work in the broader context of the subject area, and serve as an easy way to gauge their commitment to the project.

They Provide Hard Evidence of Ideas

Having many citations from a wide variety of sources related to their idea means that the student is working on a well-researched and respected subject. Citing sources that back up their claim creates room for fact-checking and further research . And, if they can cite a few sources that have the converse opinion or idea, and then demonstrate to the reader why they believe that that viewpoint is wrong by again citing credible sources, the student is well on their way to winning over the reader and cementing their point of view.

They Promote Originality and Prevent Plagiarism

The point of research projects is not to regurgitate information that can already be found elsewhere. We have Google for that! What the student’s project should aim to do is promote an original idea or a spin on an existing idea, and use reliable sources to promote that idea. Copying or directly referencing a source without proper citation can lead to not only a poor grade, but accusations of academic dishonesty. By citing their sources regularly and accurately, students can easily avoid the trap of plagiarism , and promote further research on their topic.

They Create Better Researchers

By researching sources to back up and promote their ideas, students are becoming better researchers without even knowing it! Each time a new source is read or researched, the student is becoming more engaged with the project and is developing a deeper understanding of the subject area. Proper citations demonstrate a breadth of the student’s reading and dedication to the project itself. By creating citations, students are compelled to make connections between their sources and discern research patterns. Each time they complete this process, they are helping themselves become better researchers and writers overall.

When is the Right Time to Start Making Citations?

Make in-text/parenthetical citations as you need them.

As you are writing your paper, be sure to include references within the text that correspond with references in a works cited or bibliography. These are usually called in-text citations or parenthetical citations in MLA and APA formats. The most effective time to complete these is directly after you have made your reference to another source. For instance, after writing the line from Charles Dickens’ A Tale of Two Cities : “It was the best of times, it was the worst of times…,” you would include a citation like this (depending on your chosen citation style):

(Dickens 11).

This signals to the reader that you have referenced an outside source. What’s great about this system is that the in-text citations serve as a natural list for all of the citations you have made in your paper, which will make completing the works cited page a whole lot easier. After you are done writing, all that will be left for you to do is scan your paper for these references, and then build a works cited page that includes a citation for each one.

2. Understand the General Formatting Rules of Your Citation Style Before You Start Writing

While reading up on paper formatting may not sound exciting, being aware of how your paper should look early on in the paper writing process is super important. Citation styles can dictate more than just the appearance of the citations themselves, but rather can impact the layout of your paper as a whole, with specific guidelines concerning margin width, title treatment, and even font size and spacing. Knowing how to organize your paper before you start writing will ensure that you do not receive a low grade for something as trivial as forgetting a hanging indent.

Don’t know where to start? Here’s a formatting guide on APA format .

3. Double-check All of Your Outside Sources for Relevance and Trustworthiness First

Collecting outside sources that support your research and specific topic is a critical step in writing an effective paper. But before you run to the library and grab the first 20 books you can lay your hands on, keep in mind that selecting a source to include in your paper should not be taken lightly. Before you proceed with using it to backup your ideas, run a quick Internet search for it and see if other scholars in your field have written about it as well. Check to see if there are book reviews about it or peer accolades. If you spot something that seems off to you, you may want to consider leaving it out of your work. Doing this before your start making citations can save you a ton of time in the long run.

Finished with your paper? It may be time to run it through a grammar and plagiarism checker , like the one offered by EasyBib Plus. If you’re just looking to brush up on the basics, our grammar guides  are ready anytime you are.

A Quick Guide to Referencing | Cite Your Sources Correctly

Referencing means acknowledging the sources you have used in your writing. Including references helps you support your claims and ensures that you avoid plagiarism .

There are many referencing styles, but they usually consist of two things:

• A citation wherever you refer to a source in your text.
• A reference list or bibliography at the end listing full details of all your sources.

The most common method of referencing in UK universities is Harvard style , which uses author-date citations in the text. Our free Harvard Reference Generator automatically creates accurate references in this style.

Table of contents

Referencing styles, citing your sources with in-text citations, creating your reference list or bibliography, harvard referencing examples, frequently asked questions about referencing.

Each referencing style has different rules for presenting source information. For in-text citations, some use footnotes or endnotes , while others include the author’s surname and date of publication in brackets in the text.

The reference list or bibliography is presented differently in each style, with different rules for things like capitalisation, italics, and quotation marks in references.

Your university will usually tell you which referencing style to use; they may even have their own unique style. Always follow your university’s guidelines, and ask your tutor if you are unsure. The most common styles are summarised below.

Harvard referencing, the most commonly used style at UK universities, uses author–date in-text citations corresponding to an alphabetical bibliography or reference list at the end.

Vancouver referencing, used in biomedicine and other sciences, uses reference numbers in the text corresponding to a numbered reference list at the end.

In-text citations should be used whenever you quote, paraphrase, or refer to information from a source (e.g. a book, article, image, website, or video).

Quoting and paraphrasing

Quoting is when you directly copy some text from a source and enclose it in quotation marks to indicate that it is not your own writing.

Paraphrasing is when you rephrase the original source into your own words. In this case, you don’t use quotation marks, but you still need to include a citation.

In most referencing styles, page numbers are included when you’re quoting or paraphrasing a particular passage. If you are referring to the text as a whole, no page number is needed.

In-text citations

In-text citations are quick references to your sources. In Harvard referencing, you use the author’s surname and the date of publication in brackets.

Up to three authors are included in a Harvard in-text citation. If the source has more than three authors, include the first author followed by ‘ et al. ‘

The point of these citations is to direct your reader to the alphabetised reference list, where you give full information about each source. For example, to find the source cited above, the reader would look under ‘J’ in your reference list to find the title and publication details of the source.

Placement of in-text citations

In-text citations should be placed directly after the quotation or information they refer to, usually before a comma or full stop. If a sentence is supported by multiple sources, you can combine them in one set of brackets, separated by a semicolon.

If you mention the author’s name in the text already, you don’t include it in the citation, and you can place the citation immediately after the name.

• Another researcher warns that the results of this method are ‘inconsistent’ (Singh, 2018, p. 13) .
• Previous research has frequently illustrated the pitfalls of this method (Singh, 2018; Jones, 2016) .
• Singh (2018, p. 13) warns that the results of this method are ‘inconsistent’.

The terms ‘bibliography’ and ‘reference list’ are sometimes used interchangeably. Both refer to a list that contains full information on all the sources cited in your text. Sometimes ‘bibliography’ is used to mean a more extensive list, also containing sources that you consulted but did not cite in the text.

A reference list or bibliography is usually mandatory, since in-text citations typically don’t provide full source information. For styles that already include full source information in footnotes (e.g. OSCOLA and Chicago Style ), the bibliography is optional, although your university may still require you to include one.

Format of the reference list

Reference lists are usually alphabetised by authors’ last names. Each entry in the list appears on a new line, and a hanging indent is applied if an entry extends onto multiple lines.

Different source information is included for different source types. Each style provides detailed guidelines for exactly what information should be included and how it should be presented.

Below are some examples of reference list entries for common source types in Harvard style.

• Chapter of a book
• Journal article

Correct my document today

Your university should tell you which referencing style to follow. If you’re unsure, check with a supervisor. Commonly used styles include:

• Harvard referencing , the most commonly used style in UK universities.
• MHRA , used in humanities subjects.
• APA , used in the social sciences.
• Vancouver , used in biomedicine.
• OSCOLA , used in law.

Your university may have its own referencing style guide.

If you are allowed to choose which style to follow, we recommend Harvard referencing, as it is a straightforward and widely used style.

References should be included in your text whenever you use words, ideas, or information from a source. A source can be anything from a book or journal article to a website or YouTube video.

If you don’t acknowledge your sources, you can get in trouble for plagiarism .

To avoid plagiarism , always include a reference when you use words, ideas or information from a source. This shows that you are not trying to pass the work of others off as your own.

You must also properly quote or paraphrase the source. If you’re not sure whether you’ve done this correctly, you can use the Scribbr Plagiarism Checker to find and correct any mistakes.

Harvard referencing uses an author–date system. Sources are cited by the author’s last name and the publication year in brackets. Each Harvard in-text citation corresponds to an entry in the alphabetised reference list at the end of the paper.

Vancouver referencing uses a numerical system. Sources are cited by a number in parentheses or superscript. Each number corresponds to a full reference at the end of the paper.

Reference List: Basic Rules

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

This resourse, revised according to the 7 th  edition APA Publication Manual, offers basic guidelines for formatting the reference list at the end of a standard APA research paper. Most sources follow fairly straightforward rules. However, because sources obtained from academic journals  carry special weight in research writing, these sources are subject to special rules . Thus, this page presents basic guidelines for citing academic journals separate from its "ordinary" basic guidelines. This distinction is made clear below.

Note:  Because the information on this page pertains to virtually all citations, we've highlighted one important difference between APA 6 and APA 7 with an underlined note written in red.  For more information, please consult the   Publication Manual of the American Psychological Association , (7 th  ed.).

Formatting a Reference List

Your reference list should appear at the end of your paper. It provides the information necessary for a reader to locate and retrieve any source you cite in the body of the paper. Each source you cite in the paper must appear in your reference list; likewise, each entry in the reference list must be cited in your text.

Your references should begin on a new page separate from the text of the essay; label this page "References" in bold, centered at the top of the page (do NOT underline or use quotation marks for the title). All text should be double-spaced just like the rest of your essay.

Basic Rules for Most Sources

• All lines after the first line of each entry in your reference list should be indented one-half inch from the left margin. This is called hanging indentation.
• All authors' names should be inverted (i.e., last names should be provided first).
• For example, the reference entry for a source written by Jane Marie Smith would begin with "Smith, J. M."
• If a middle name isn't available, just initialize the author's first name: "Smith, J."
• Give the last name and first/middle initials for all authors of a particular work up to and including 20 authors ( this is a new rule, as APA 6 only required the first six authors ). Separate each author’s initials from the next author in the list with a comma. Use an ampersand (&) before the last author’s name. If there are 21 or more authors, use an ellipsis (but no ampersand) after the 19th author, and then add the final author’s name.
• Reference list entries should be alphabetized by the last name of the first author of each work.
• For multiple articles by the same author, or authors listed in the same order, list the entries in chronological order, from earliest to most recent.
• Note again that the titles of academic journals are subject to special rules. See section below.
• Italicize titles of longer works (e.g., books, edited collections, names of newspapers, and so on).
• Do not italicize, underline, or put quotes around the titles of shorter works such as chapters in books or essays in edited collections.

Basic Rules for Articles in Academic Journals

• Present journal titles in full.
• Italicize journal titles.
• For example, you should use  PhiloSOPHIA  instead of  Philosophia,  or  Past & Present   instead of  Past and Present.
• This distinction is based on the type of source being cited. Academic journal titles have all major words capitalized, while other sources' titles do not.
• Capitalize   the first word of the titles and subtitles of   journal articles , as well as the   first word after a colon or a dash in the title, and   any proper nouns .
• Do not italicize or underline the article title.
• Deep blue: The mysteries of the Marianas Trench.
• Oceanographic Study: A Peer-Reviewed Publication

Please note:  While the APA manual provides examples of how to cite common types of sources, it does not cover all conceivable sources. If you must cite a source that APA does not address, the APA suggests finding an example that is similar to your source and using that format. For more information, see page 282 of the   Publication Manual of the American Psychological Association , 7 th  ed.

How to Write References in Research Papers: Navigating the Maze (Part 2)

You truly are navigating a maze when it comes to ci tations and the question of how to write references in research pa per s. In part 1 of this article, we touched upon citations, which are pointers embedded in the text of a research paper, to sources of information or to other research relevant to that being described in the research paper. Those pointers lead to references in research papers , which typically appear at the end of the text. Whereas citations merely point us to sources in research papers, references describe those sources in sufficient detail for readers (1) to know the title of each source, who is responsible for its content, and when it was published; (2) to look up those sources; and (3) to obtain the documents in question if required.  

Table of Contents

Types of references in research papers

In writing a research paper, a researcher draws upon many sources of information, knowledge, opinions, and so on. One of the the most common type s of reference s  in research papers is other research papers published in journals; other common sources include technical reports, handbooks, presentations at conferences, and books. Increasingly, the sources in research papers are digital and include web pages, databases, blog posts, and even tweets and emails.  

Not all sources are considered equally credible , and some may not be accessible to all because they are behind paywalls or available only to members of a network (company intranets, for example) or because they are personal exchanges.

If the citations follow the Harvard system, references in a research paper s are sorted alphabetically by the last name of the first author; if the citations follow the Vancouver system, the references are arranged by numbers: the reference corresponding to the first numbered citation is numbered 1, and so on. If a source is cited again, its allocated number does not change.  

Some additional conventions govern the alphabetic sorting of references in research papers . For instance, when authors have some papers in which they are the only author and others in which they have one or more co-authors or when the same author or authors have papers published in different years or even within the same year.  

Some publishers make even greater demands of references in research papers : authors are expected to sort the list of references alphabetically, as in the Harvard system; then number the sorted list serially; and then renumber all the citations within the text so that each corresponds to its new number!  

How to add references in a research paper: Key elements

For a source of information to be described accurately, some minimum details are required. Here’s one example of w rit ing references in research paper s – ‘ Nature 171 : 737’ is a code that, if you know how to decipher it, tells you that it means an article published in Nature (a weekly journal published from the UK) that begins on page 737 of volume 171 of that journal. However, it does not tell you what the article was about, who wrote it, when it was published, or even how long it is. A complete reference in research paper s (Fig. 1), however, tells you that the title of the article was ‘Molecular structure of nucleic acids: a structure for deoxyribose nucleic acid’, that it was written by J. D. Watson and F. H. C. Crick, that it was published in 1953, and that it ran to no more than two pages.  

When thinking about how to write research references , remember that the elements that make up a reference to an article published in a journal are different from those that make up a reference to a book (edition if not the first, the publisher, and the place of publication, although the last is no longer considered essential in today’s globalized publishing). The elements that make up a reference to a technical report include the name of the organization issuing that report and the report number, if any, and that to a conference presentation gives the title of the conference, the date(s) on which it was held and the place, the name of the organizer(s) of the conference, and so on.  

Note that journals or publishers differ in the elements they expect authors to include when they state how to put references in research papers ; for example, some journals give only minimal information and exclude the titles of articles and some use the ‘elided’ form of page numbers (737–38 instead of 737–738, for example).  

Then there is the question of abbreviated names of journals: some publishers abbreviate journal titles and some don’t ( Annals of Applied Biology or Ann. Appl. Biol.). And those who do, often disagree on the correct abbreviation—and on whether the abbreviations should end in dots (whether the word ‘Journal’ should be given as J. or J or Jnl or Jnl.).  

Sequence of the elements that make up reference s in research papers  

Publishers and journals also differ in the order or sequence in which they present the elements or components of reference s in research papers : usually, British and European publishers put the year of publication after the names of authors whereas US publishers move the year closer to the volume number of the journal.  

Even within an element, the sequence of references in research paper s can have subtle differences. In Harvard system, because the last name of the first author is using for sorting, the name is ‘inverted’, that is the last name is given first, followed by initials (Watson J D instead of J D Watson). However, some journals invert the names of all the authors whereas some invert the name of only the first author. In Vancouver system, the names are seldom inverted because the sequence is not alphabetical.  

Punctuation to separate the elements that make up references in research papers

The many exasperating details that go into formatting references include punctuation marks (or their absence). In giving the initials of authors, some journals use dots, some journals use space, some use both, and some use neither (Watson J.D. or Watson J D or Watson J. D. or Watson JD). Some use a comma between the last name and the initials whereas some reserve the comma only to separate one name from the next (Watson, J D and Crick, F H C or Watson J D, Crick F H C). Some use ‘and’ some don’t, even when there are only two authors, and some use ‘&’ instead which makes it even more confusing for those struggling with how to write references in a research paper.

When the place of publication was a required element in the case of books, some publishers used the colon and some used the comma (and also changed the order, as in New York: Harper & Row or Harper & Row, New York). Some publishers end each reference with a full stop (period) and some don’t.

Typography of references in research papers  

As if the variations mentioned above were not enough, when figuring out how to add references in a research paper , you also have to contend with the differences in typography as well: journal titles in italics or in normal type, volume numbers in bold or in normal type, hyphens or en dashes between page numbers (737-738 or 737–738), and so on.  

All is not lost, however, if you despair of ever getting the references in a research paper right. For example, some publishers now insist on correct formatting only after a paper has been accepted for publication. Also, ICMJE, the International Committee of Medical Journal Editors, recommends a set of uniform requirements for manuscripts (the requirements include the formatting of citations and references), and hundreds of medical journals ( www.icmje.org/journals-following-the-icmje-recommendations/ ) have agreed that as long as authors adhere to those recommendations on how to mention references for research papers , any changes to the formatting any journal wants to make will be made by the journal in question.  

Lastly, several software packages help authors to automate this mundane task of consistent formatting of references in research paper s—but that is another article and another day.  

The details involved in using citations and references correctly can be overwhelming for some of us. While this article covers the key tips to help you understand how to give reference s in research paper s , be sure to check out article 1 of this two-part series for more on what, when and how to cite in a research paper. One way to check whether these are handled correctly in your manuscript is to use Researcher.Life’s AI powered manuscript optimizer , which can flag any discrepancies, departures from standard style, and mismatches between citations and references in research paper s.

When writing a paper for a research project, you may need to cite a research paper you used as a reference. The basic information included in your citation will be the same across all styles. However, the format in which that information is presented is somewhat different depending on whether you're using American Psychological Association (APA), Modern Language Association (MLA), Chicago, or American Medical Association (AMA) style.

Referencing a Research Paper

• In APA style, cite the paper: Last Name, First Initial. (Year). Title. Publisher.
• In Chicago style, cite the paper: Last Name, First Name. “Title.” Publisher, Year.
• In MLA style, cite the paper: Last Name, First Name. “Title.” Publisher. Year.

Citation Help

• For example: "Kringle, K., & Frost, J."

• For example: "Kringle, K., & Frost, J. (2012)."
• If the date, or any other information, are not available, use the guide at https://blog.apastyle.org/apastyle/2012/05/missing-pieces.html .

• For example: "Kringle, K., & Frost, J. (2012). Red noses, warm hearts: The glowing phenomenon among North Pole reindeer."
• If you found the research paper in a database maintained by a university, corporation, or other organization, include any index number assigned to the paper in parentheses after the title. For example: "Kringle, K., & Frost, J. (2012). Red noses, warm hearts: The glowing phenomenon among North Pole reindeer. (Report No. 1234)."

• For example: "Kringle, K., & Frost, J. (2012). Red noses, warm hearts: The glowing phenomenon among North Pole reindeer. (Report No. 1234). Retrieved from Alaska University Library Archives, December 24, 2017."

• For example: "(Kringle & Frost, 2012)."
• If there was no date on the research paper, use the abbreviation n.d. : "(Kringle & Frost, n.d.)."

• For example: "Kringle, Kris, and Jack Frost."

• For example: "Kringle, Kris, and Jack Frost. "Red Noses, Warm Hearts: The Glowing Phenomenon among North Pole Reindeer." Master's thesis."

• For example: "Kringle, Kris, and Jack Frost. "Red Noses, Warm Hearts: The Glowing Phenomenon among North Pole Reindeer." Master's thesis, Alaska University, 2012."

• For example: "Kringle, Kris, and Jack Frost. "Red Noses, Warm Hearts: The Glowing Phenomenon among North Pole Reindeer." Master's thesis, Alaska University, 2012. Accessed at https://www.northpolemedical.com/raising_rudolf."

• Footnotes are essentially the same as the full citation, although the first and last names of the authors aren't inverted.
• For parenthetical citations, Chicago uses the Author-Date format. For example: "(Kringle and Frost 2012)."

• For example: "Kringle, Kris, and Frost, Jack."

• For example: "Kringle, Kris, and Frost, Jack. "Red Noses, Warm Hearts: The Glowing Phenomenon Among North Pole Reindeer.""

• For example, suppose you found the paper in a collection of paper housed in university archives. Your citation might be: "Kringle, Kris, and Frost, Jack. "Red Noses, Warm Hearts: The Glowing Phenomenon Among North Pole Reindeer." Master's Theses 2000-2010. University of Alaska Library Archives. Accessed December 24, 2017."

• For example: "(Kringle & Frost, p. 33)."

• For example: "Kringle K, Frost J."

• For example: "Kringle K, Frost J. Red noses, warm hearts: The glowing phenomenon among North Pole reindeer."

• For example: "Kringle K, Frost J. Red noses, warm hearts: The glowing phenomenon among North Pole reindeer. Nat Med. 2012; 18(9): 1429-1433."

• For example, if you're citing a paper presented at a conference, you'd write: "Kringle K, Frost J. Red noses, warm hearts: The glowing phenomenon among North Pole reindeer. Oral presentation at Arctic Health Association Annual Summit; December, 2017; Nome, Alaska."
• To cite a paper you read online, you'd write: "Kringle K, Frost J. Red noses, warm hearts: The glowing phenomenon among North Pole reindeer. https://www.northpolemedical.com/raising_rudolf"

• For example: "According to Kringle and Frost, these red noses indicate a subspecies of reindeer native to Alaska and Canada that have migrated to the North Pole and mingled with North Pole reindeer. 1 "

Writing Research Papers

• What Types of References Are Appropriate?

When writing a research paper, there are many different types of sources that you might consider citing.  Which are appropriate?  Which are less appropriate?  Here we discuss the different types of sources that you may wish to use when working on a research paper.   

Please note that the following represents a general set of recommended guidelines that is not specific to any class and does not represent department policy.  The types of allowable sources may vary by course and instructor.

Highly appropriate: peer-reviewed journal articles

In general, you should primarily cite peer-reviewed journal articles in your research papers.  Peer-reviewed journal articles are research papers that have been accepted for publication after having undergone a rigorous editorial review process.  During that review process, the article was carefully evaluated by at least one journal editor and a group of reviewers (usually scientists that are experts in the field or topic under investigation).  Often the article underwent revisions before it was judged to be satisfactory for publication. 

Most articles submitted to high quality journals are not accepted for publication.  As such, research that is successfully published in a respected peer-reviewed journal is generally regarded as higher quality than research that is not published or is published elsewhere, such as in a book, magazine, or on a website.  However, just because a study was published in a peer-reviewed journal does not mean that it is free from error or that its conclusions are correct.  Accordingly, it is important to critically read and carefully evaluate all sources, including peer-reviewed journal articles.

Tips for finding and using peer-reviewed journal articles:

• Many databases, such as PsycINFO, can be set to only search for peer-reviewed journal articles. Other search engines, such as Google Scholar, typically include both peer-reviewed and not peer-reviewed articles in search results, and thus should be used with greater caution. 
• Even though a peer-reviewed journal article is, by definition, a source that has been carefully vetted through an editorial process, it should still be critically evaluated by the reader. 

Potentially appropriate: books, encyclopedias, and other scholarly works

Another potential source that you might use when writing a research paper is a book, encyclopedia, or an official online source (such as demographic data drawn from a government website).  When relying on such sources, it is important to carefully consider its accuracy and trustworthiness.  For example, books vary in quality; most have not undergone any form of review process other than basic copyediting.  In many cases, a book’s content is little more than the author’s informed or uninformed opinion. 

However, there are books that have been edited prior to publication, as is the case with many reputable encyclopedias; also, many books from academic publishers are comprised of multiple chapters, each written by one or more researchers, with the entire volume carefully reviewed by one or more editors.  In those cases, the book has undergone a form of peer review, albeit often not as rigorous as that for a peer-reviewed journal article.

Tips for using books, encyclopedias, and other scholarly works:

• When using books, encyclopedias, and other scholarly works (that is, works written or produced by researchers, official agencies, or corporations), it is important to very carefully evaluate the quality of that source.
• If the source is an edited volume (in which case in the editor(s) will be listed on the cover), is published by a reputable source (such as Academic Press, MIT Press, and others), or is written by a major expert in the field (such as a researcher with a track record of peer-reviewed journal articles on the subject), then it is more likely to be trustworthy.
• For online encyclopedias such as Wikipedia, an instructor may or may not consider that an acceptable source (by default, don’t assume that a non-peer reviewed source will be considered acceptable). It is best to ask the instructor for clarification. 1

Usually inappropriate: magazines, blogs, and websites  

Most research papers can be written using only peer-reviewed journal articles as sources.  However, for many topics it is possible to find a plethora of sources that have not been peer-reviewed but also discuss the topic.  These may include articles in popular magazines or postings in blogs, forums, and other websites.  In general, although these sources may be well-written and easy to understand, their scientific value is often not as high as that of peer-reviewed articles.  Exceptions include some magazine and newspaper articles that might be cited in a research paper to make a point about public awareness of a given topic, to illustrate beliefs and attitudes about a given topic among journalists, or to refer to a news event that is relevant to a given topic. 

Tips for using magazines, blogs, and websites:

• Avoid such references if possible. You should primarily focus on peer-reviewed journal articles as sources for your research paper.  High quality research papers typically do not rely on non-academic and not peer-reviewed sources.
• Refer to non-academic, not peer-reviewed sources sparingly, and if you do, be sure to carefully evaluate the accuracy and scientific merit of the source.

Academic Referencing: How to Cite a Research Paper

Learning how to conduct accurate, discipline-specific academic research can feel daunting at first. But, with a solid understanding of the reasoning behind why we use academic citations coupled with knowledge of the basics, you’ll learn how to cite sources with accuracy and confidence.

When it comes to academic research, citing sources correctly is arguably as important as the research itself. "Your instructors are expecting your work to adhere to these professional standards," said Amanda Girard , research support manager of Shapiro Library at Southern New Hampshire University (SNHU).

With Shapiro Library for the past three years, Girard manages the library’s research support services, which includes SNHU’s 24/7 library chat and email support. She holds an undergraduate degree in professional writing and a graduate degree in library and information science. She said that accurate citations show that you have done your research on a topic and are knowledgeable about current ideas from those actively working in the field.

In other words, when you cite sources according to the academic style of your discipline, you’re giving credit where credit is due.

Why Cite Sources?

Citing sources properly ensures you’re following high academic and professional standards for integrity and ethics.

“When you cite a source, you can ethically use others’ research. If you are not adequately citing the information you claim in your work, it would be considered plagiarism ,” said Shannon Geary '16 , peer tutor at SNHU.

Geary has an undergraduate degree in communication  from SNHU and has served on the academic support team for close to 2 years. Her job includes helping students learn how to conduct research  and write academically.

“In academic writing, it is crucial to state where you are receiving your information from,” she said. “Citing your sources ensures that you are following academic integrity standards.”

According to Geary and Girard, several key reasons for citing sources are:

• Access. Citing sources points readers to original sources. If anyone wants to read more on your topic, they can use your citations as a roadmap to access the original sources.
• Attribution. Crediting the original authors, researchers and experts  shows that you’re knowledgeable about current ideas from those actively working in the field and adhering to high ethical standards, said Girard.
• Clarity. “By citing your sources correctly, your reader can follow along with your research,” Girard said.
• Consistency. Adhering to a citation style provides a framework for presenting ideas within similar academic fields. “Consistent formatting makes accessing, understanding and evaluating an author's findings easier for others in related fields of study,” Geary said.
• Credibility. Proper citation not only builds a writer's authority but also ensures the reliability of the work, according to Geary.

Ultimately, citing sources is a formalized way for you to share ideas as part of a bigger conversation among others in your field. It’s a way to build off of and reference one another’s ideas, Girard said.

How Do You Cite an Academic Research Paper?

Any time you use an original quote or paraphrase someone else’s ideas, you need to cite that material, according to Geary.

“The only time we do not need to cite is when presenting an original thought or general knowledge,” she said.

While the specific format for citing sources can vary based on the style used, several key elements are always included, according to Girard. Those are:

• Title of source
• Type of source, such as a journal, book, website or periodical

By giving credit to the authors, researchers and experts you cite, you’re building credibility. You’re showing that your argument is built on solid research.

“Proper citation not only builds a writer's authority but also ensures the reliability of the work,” Geary said. “Properly formatted citations are a roadmap for instructors and other readers to verify the information we present in our work.”

Common Citation Styles in Academic Research

Certain disciplines adhere to specific citation standards because different disciplines prioritize certain information and research styles . The most common citation styles used in academic research, according to Geary, are:

• American Psychological Association, known as APA . This style is standard in the social sciences such as psychology, education and communication. “In these fields, research happens rapidly, which makes it exceptionally important to use current research,” Geary said.
• Modern Language Association, known as MLA . This style is typically used in literature and humanities because of the emphasis on literature analysis. “When citing in MLA, there is an emphasis on the author and page number, allowing the audience to locate the original text that is being analyzed easily,” Geary said.
• Chicago Manual of Style, known as Chicago . This style is typically used in history, business and sometimes humanities. “(Chicago) offers flexibility because of the use of footnotes, which can be seen as less distracting than an in-text citation,” Geary said.

The benefit of using the same format as other researchers within a discipline is that the framework of presenting ideas allows you to “speak the same language,” according to Girard.

APA Citation for College: A Brief Overview

Are you writing a paper that needs to use APA citation, but don’t know what that means? No worries. You’ve come to the right place.

How to Use MLA Formatting: A Brief Overview

Are you writing a paper for which you need to know how to use MLA formatting, but don’t know what that means? No worries. You’ve come to the right place.

How to Ensure Proper Citations

Keeping track of your research as you go is one of the best ways to ensure you’re citing appropriately and correctly based on the style that your academic discipline uses.

“Through careful citation, authors ensure their audience can distinguish between borrowed material and original thoughts, safeguarding their academic reputation and following academic honesty policies,” Geary said.

Some tips that she and Girard shared to ensure you’re citing sources correctly include:

• Keep track of sources as you work. Writers should keep track of their sources every time an idea is not theirs, according to Geary. “You don’t want to find the perfect research study and misplace its source information, meaning you’d have to omit it from your paper,” she said.
• Practice. Even experienced writers need to check their citations before submitting their work. “Citing requires us to pay close attention to detail, so always start your citation process early and go slow to ensure you don’t make mistakes,” said Geary. In time, citing sources properly becomes faster and easier.
• Use an Online Tool . Geary recommends the Shapiro Library citation guide . You can find sample papers, examples of how to cite in the different academic styles and up-to-date citation requirements, along with information and examples for APA, MLA and Chicago style citations.
• Work with a Tutor. A tutor can offer support along with tips to help you learn the process of academic research. Students at SNHU can connect with free peer tutoring through the Academic Support tab in their online courses, though many colleges and universities offer peer tutoring.

How to cite a reference in academic writing.

A citation consists of two pieces: an in-text citation that is typically short and a longer list of references or works cited (depending on the style used) at the end of the paper.

“In-text citations immediately acknowledge the use of external source information and its exact location,” Geary said. While each style uses a slightly different format for in-text citations that reference the research, you may expect to need the page number, author’s name and possibly date of publication in parentheses at the end of a sentence or passage, according to Geary.

A longer entry listing the complete details of the resource you referenced should also be included on the references or works cited page at the end of the paper. The full citation is provided with complete details of the source, such as author, title, publication date and more, Geary said.

The two-part aspect of citations is because of readability. “You can imagine how putting the full citation would break up the flow of a paper,” Girard said. “So, a shortened version is used (in the text).”

“For example, if an in-text citation reads (Jones, 2024), the reader immediately knows that the ideas presented are coming from Jones’s work, and they can explore the comprehensive citation on the final page,” she said.

The in-text citation and full citation together provide a transparent trail of the author's process of engaging with research.

“Their combined use also facilitates further research by following a standardized style (APA, MLA, Chicago), guaranteeing that other scholars can easily connect and build upon their work in the future,” Geary said.

Developing and demonstrating your research skills, enhancing your work’s credibility and engaging ethically with the intellectual contributions of others are at the core of the citation process no matter which style you use.

Introduction

The value of scientific research lies in its wide visibility and access/availability to others; this is generally achieved by a scientific publication as an original (research) paper. The scientific inquiry typically advances based on previously laid ideas/research, making it essential to acknowledge the contribution of the previous authors. The references list is a catalog of literature sources chosen by the researcher to represent the most relevant documents pertaining to his/her study.[ 1 ] The British Standards Institution defines reference as “a set of data describing a document, sufficiently precise and detailed to identify it and enable it to be located.” [ 2 ] References lay the foundation of the paper, providing context for the hypothesis, methodology, interpretation, and justification of the study.[ 3 ] Using other's ideas/thoughts without due credit amounts to plagiarism, compromising the academic integrity of research. A well-referenced paper is thus accurate and complete, adds value and credibility to both the researcher and the source author, and enhances the scientific prestige of the chosen journal.[ 3 ] A bibliography also lists the sources used during research. However, while references only include those sources (journals, books, web information, etc.) which are actually cited in the publication, bibliography comprises all accessed sources (works consulted), irrespective of whether they are cited in the study publication or not.[ 4 ] Thus, referencing in academic writing is an important research tool to display as well as integrate knowledge on a particular subject or topic.[ 5 ]

Importance of Proper Referencing

Scientific research is usually developed on previously established ideas/scientific knowledge. A meticulous literature review at the beginning of the study enables the researcher to identify the work done in the field, identify the gaps in knowledge, and recognize the need for further research.[ 6 ] The most relevant sources from this literature search (essentially) form the list of references. Use of proper referencing is thus beneficial in many ways, such as the following:

• a) It helps the readers to identify and locate the sources used in the research and provides evidence to verify the need/rationale of the study, methodology, inferences, and implications of the study.[ 3 ]
• b) It provides an overview of the techniques/tools used, supports/convinces the reader about the appropriateness of the methodology, and offers a proper perspective in which the research findings need to be interpreted.[ 3 , 7 ]
• c) It is a proof of the author's in-depth reading and knowledge on the subject pertaining to his/her research. References not only highlight similarities in research, but also differentiate the author's ideas from his sources, indirectly acknowledging the author's own contribution to that topic.[ 4 ]
• d) References chosen by a researcher not only credit the individual author/s whose work is cited, but also demonstrate his/her appreciation toward cited authors, at times leading readers toward hitherto lesser-known/unknown author's research.[ 4 , 8 ] By providing acknowledgment to the cited idea/thought, the author also avoids being accused of plagiarism and adds credibility to his/her own work.[ 4 ]
• e) Referenced works steer the readers toward literature pertaining to a particular topic, thus advancing the readers’ interest.[ 4 ] It also allows to trace the origins of ideas and integrates newer ideas (from current research) with previous ones, thus building a web of learning about the topic of interest.[ 9 ]
• f) The reference list provides a list of experts in a specific field, thus helping editors to identify appropriate reviewers.[ 3 ]
• g) It provides peer reviewers with related sources of information to evaluate the manuscript with respect to the cited work.[ 6 ]

Organizing the References

An initial extensive literature search helps in identifying the appropriate research question, drafting the study protocol, supervising ongoing research, analyzing the results, and writing the paper.[ 3 , 7 ] Although references are displayed at the end of the article/after the text of the article, they should not be actually written after completing the text of the manuscript. While drafting the text of the manuscript, the author/s should type the references on a separate MS Word document simultaneously. This preparation allows the writer to choose adequate number of relevant and rational references, avoid bias in his/her research/writing, and limit the reference number as per the target journal for publication.[ 7 ] While citing, it is imperative not to cite broadly, but to do so with respect to the content of the article. Articles which define the topic, lay down background information regarding the study question, give current knowledge about the research, and describe previous studies on a similar study question should be mentioned in the “Introduction” section of the manuscript.[ 10 ] These studies enable to identify existing knowledge, gaps in knowledge, and justify the rationale of the study.[ 6 ] Studies which identify or refer to the method, protocols, or standards (whether new or previously published), elaborate on complex or lesser-known statistical analysis, describe diagnostic criteria, rationalize sample size estimation, or justify use of specific study design/method are best suited as references to the “Methods” section of the manuscript – they help to plan a strong and supported methodology and describe the technique and criteria of the study group.[ 3 , 10 ] Research that reflects on the study findings/results or provides supportive explanation merit mention in the “Discussion” section of the manuscript – they provide information to interpret the study based on existing published data, compare results with those of other studies, and rationalize the implications of the results.[ 10 ]

Though citation analysis treats all references equally, it is important to weigh references in terms of their value to the paper.[ 11 ] While some references are worthy to be mentioned only once in the paper, some are very relevant to the study question and referred to on multiple occasions, and it is important to re-cite only the most relevant articles.[ 3 ] Referencing is not just about stating the publication source (providing relatedness), but also adds value to the paper in terms of representation on the subject and connectivity between knowledge sources (capture the “aboutness”).[ 11 ] References can be books (author/s), legal documents, journal articles, newspaper articles, reports (e.g., official reports from government departments), university working papers, papers presented at conferences, internet sources (including weblogs – blogs and email correspondence), DVD/CD databases, radio/television/videos/audio cassette/CD-ROMs, interview transcripts, and illustrations.[ 12 ]

Choosing Appropriate References

As a rule, whenever one uses an idea, data, diagrams, tables, concepts, methods from a previously published work, it should be cited.[ 12 ] With availability of multiple search engines and abundance of online resources, the task of filtering references may seem daunting.[ 5 ] While choosing references, one should ensure that the original source is completely read and correctly interpreted before its citing.[ 6 ] It is preferable to provide direct references to original article sources as far as possible, choosing a landmark article on the topic.[ 5 ] The choice of references should serve as the most relevant, appropriate, and valuable addition, and one should stick to the most pertinent references that actively support/contradict their conclusions or experience.[ 6 ] It is preferable to use the most recent relevant resources to provide the latest and up-to-date information; however, certain landmark papers may also be cited (even if they are old). Note that very old references may not be available/accessible to reviewers as well as readers.[ 7 ] Often, there are multiple sources for the same information; always prefer references that provide the highest level of evidence (such as meta-analysis), most recent publications, or trustworthy sources such as reputed peer-reviewed journals (with higher impact factor), open access and preferably indexed on reputed databases such as MEDLINE and PubMed.[ 13 , 14 ] Citing works from the journal one wishes to submit demonstrates that author follows that particular journal's publications and values it; however, one should refrain from unethical practices such as coercive citation (when authors are coerced/directed to add irrelevant citations from the editor's journals) or padded citation (when authors pad their reference list with superfluous citations).[ 14 , 15 , 16 ] There should be a judicious combination of original as well as review articles. Review articles summarize a large body of literature and reduce the number of references; however they may be biased and may not reflect the original article accurately.[ 16 ] One should stick to the journal guidelines rigorously (in terms of style and number) to avoid rejection or delay in the processing of the manuscript.[ 6 ] Avoid citing conference abstracts as far as possible, as they provide incomplete or limited information on the subject and often lack an appropriate peer review.[ 16 ] Other sources which lack traditional review and thus may cite inappropriate, unchecked, or promotional content include online sources, such as audio and video presentations, and should therefore be used with caution.[ 17 ] It is also prudent to avoid personal communications and limit their use to situations where essential information is unavailable from a public source (if permission is necessary, then name and date of the communication should be cited in brackets in text).[ 16 ] Limit self-citations to the bare crucial ones that are necessary.[ 18 ] Articles accepted but awaiting publications should be cited as “in press.”[ 16 ] Articles submitted but not yet published should be referenced as “unpublished observations” with written permission from the source; however, since they have not undergone a peer review, they should be (preferably) avoided.[ 16 ] It is prudent to avoid citing articles published in predatory journals.[ 16 ]

There is no need to provide references to facts that are expected to be well known to the journal readers, including historical overviews, own experiences, while outlining previously referenced ideas in conclusions, or while summarizing what is regarded as “common knowledge.”[ 12 ] One should be careful with online sources. There may be errors while copying the uniform resource locator (URL) or the webpage, or the website may change or be closed/inaccessible; hence, cite them only if very essential and check for their reliability and give the date of access.[ 3 ] It is preferable to use online sources with digital object identifiers (DOIs), assuring their permanent presence.[ 13 ] Also, before submission, it is worthwhile to check the US National Library of Medicine's (NLM's) PubMed database ( http://www.pubmed.org ) for any recently published articles related to the manuscript's topic.[ 19 ]

The number of references is determined by the target journal requirements as well as the type of manuscript submitted; for example, the Journal of Postgraduate Medicine allows about 30 references for original articles, up to 15 references for brief reports/grand rounds/clinicopathological forum, 12 references for case series, up to 10 references for case reports/research letter, and five references for a letter to editor ( https://www.jpgmonline.com/contributors.asp#Ref ).

Preparing the References

Citation consists of two components – the “in-text citation” and the “reference list.”[ 7 ] In the in-text citation, quotation marks are used to cite an exact line/phrase from another source, specifically for definitions, examples, or explanations provided by another/earlier author/s.[ 13 ] To prevent plagiarism, it is suitable to interpret and then summarize the cited content in one's own words, referencing the source at the end of the sentence.[ 14 ]

The parts and order in the citation depend on the source which the author is referencing (journal, book, book chapter, or web source) and the journal guidelines. It is imperative to go through the target journal rules and follow the “Instructions to Authors” related to referencing guidelines (the style, punctuation, italics, abbreviations, issue number, volume number, and pages). All the references are generally cited and numbered as per the order in which they are mentioned in the text (and are to be inserted immediately after the source information and not necessarily at the end of the sentence, especially when multiple facts are stated in a single sentence).[ 6 ] In case of a table or a figure, the citation number should be in sequence to that of the preceding text.[ 7 ] The same reference number in which the source is first cited should be used throughout the manuscript (if cited again) as well as in the reference list.[ 7 ] The citation numbers are placed as superscript/in parentheses as per the journal guidelines.[ 7 ] In case of multiple citations, place them immediately after the fact; they should be placed in order of their chronology of publication (or alphabetically if published in the same year) separated by commas.[ 6 , 7 ] If many references are cited consecutively, the numbers can be separated by a hyphen.[ 7 ]

Any documented knowledge (text, audio, or visual) can serve as a source of reference. They can be print based or electronic and include journals, books, doctoral theses, conference papers, newspapers and magazines, web pages, and so on.[ 4 ]

The basic elements while referencing are as follows:[ 13 , 20 ]

• Journal/research paper: Name of author/s, title of paper, journal title (often abbreviated according to the style used for MEDLINE [ www.ncbi.nlm.nih.gov/nlmcatalog/journals ]),[ 16 ] publication year, volume number, issue number (issue number is kept optional by many journals), and page numbers (starting and ending page numbers or e-article number if the journal does not allot page numbers but allots e-article numbers only)[ 13 ]
• Book/chapter: Chapter author/s, title of chapter, editor/s, name of book, edition, publisher, city of publication, year of publication, and page numbers[ 13 ]
• Web sources: Names of author/s, title of webpage, year, weblink, date of access, and other information such as publisher, year of publication, and date of recent update (as may be applicable/available).[ 13 ] When citing a webpage, provide the DOI or URL of the original source as far as possible.[ 1 , 20 ]

Special attention needs to be paid to the punctuations while composing the reference, and the authors must adhere to the style recommended by the journal (that the manuscript will be eventually submitted to). Note that with each revision that the author makes in the manuscript, there may be changes in the order, addition, or deletion of references, and these adjustments should be meticulously ensured to avoid referencing errors.[ 3 ] It is also the author's responsibility to ensure that every citation has a corresponding reference and every reference is cited in the right place and context in the manuscript.[ 6 ] To avoid citation errors, the authors must verify each reference against an electronic bibliographic source like PubMed or print/pdf copies of original resources.[ 16 ] Authors should also verify that none of the cited references is a retracted article; this can be done via MEDLINE by searching PubMed for “Retracted publication [publication type]” or by going directly to the PubMed's list of retracted publications ( https://www.ncbi.nlm.nih.gov/pubmed/?termretractedpublication[publication type] ).[ 16 ]

“Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals” issued by the International Committee of Medical Journal Editors (ICMJE) provides specific information on how to cite sources, which should be followed.[ 16 ] These recommendations by the ICMJE summarize and provide regular updates on how to cite various sources (print documents; unpublished material; audio and visual media; material on CD-ROM, DVD, or disk; and material on the Internet) via Sample References ( www.nlm.nih.gov/bsd/uniform_requirements.html ) on their webpage.[ 16 ] Detailed information is also available in the NLM's Citing Medicine, 2 nd edition ( www.ncbi.nlm.nih.gov/books/NBK7256/ ).[ 20 ] Number of references to be cited should be in accordance with/within the limits as stated in the “Author Guidelines” issued by the target journal.[ 7 ] Authors should take precaution, so as to avoid citing the same reference twice in the list of references.

Types of Referencing Formats/Styles

“Citation style” is the standard format in which the source is documented in the text as well as in the reference list at the end of the manuscript.[ 4 ] In-text citation styles can be broadly classified into numerical referencing style (Numeric style/Vancouver/Institute of Electrical and Electronic Engineers [IEEE] and Running notes style/Modern Humanities Research Association [MHRA]) and name referencing style (Author Date/Harvard, American Psychological Association [APA] and Modern Languages Association [MLA]).[ 12 ] The two major used citation styles are the Vancouver and the Harvard styles, and most other styles are minor modifications of these two styles.[ 4 ] The common citation styles and their examples are summarized in Table 1 .[ 3 , 12 , 13 , 16 , 20 ] Thus, there is a wide variability in the citation style in text as well as reference list; however, the author does not have a choice, but to stick to the style recommended by the journal to which he/she wishes to submit his/her research.[ 3 ]

Common Errors in Referencing

Referencing is a tedious task and if not taken seriously and performed diligently, it is prone to many (easily avoidable) errors.[ 7 ] A reference should be accurate, clear, and consistent throughout the manuscript.[ 6 ] An incorrect reference not only questions the credibility of the paper, but also makes it difficult for the reviewers and the readers to seek the cited article, thus denying the source author of due credit for his/her work.[ 3 ] It is the author's responsibility to cite the most relevant and appropriate references in his/her research.[ 3 ] The author should not only locate, read, and understand all sources cited by him/her ( intellectual pleasure ), but also confirm the source and provide all elements of the source correctly ( accuracy ).[ 6 ] The author should be careful not to copy references from an earlier article, but should actually rewrite each selected reference afresh.[ 6 ] Some common errors occurring during referencing are summarized in Table 2 .[ 6 , 7 ]

Common errors in the “in-text citation” and the “reference list”[ 6 , 7 ]

Reference Management Software

As described earlier, there is a wide variation in the journal formatting styles and it is laborious for the researcher to store, organize, and manage the references throughout the process of literature review and protocol planning till the drafting and manuscript submission.[ 21 ] Even more challenging is the addition/deletion or reordering of references (in text as well as in the reference list) with each revision or submission to a newer journal.[ 22 ] There is an increased likelihood of making errors in citing, especially while organizing the references and writing the reference list.[ 23 ] To minimize such errors, reference management software (RMS), also known as citation management software or bibliographic management software, are available to the authors/researchers.[ 21 ] They not only help to search and retrieve the online scientific sources, but also help to import them to their database for storing, organization, and subsequent retrieval.[ 22 ] Many RMS have cloud-based storage, enabling users to be able to access the information from multiple devices as well as collaborate with other researchers.[ 22 ] RMS also allow authors to retrieve citations while writing in the format of desired journal, thus permitting to “cite while you write.”[ 14 ] They also enable addition, deletion, insertion of references in the text and automatic (auto) resequencing of their order in the main manuscript (text) as well as in the reference list.[ 22 ] They can generate reference lists in multiple formats/citation styles to suit the target journal requirements and allow conversion of one format style to another with ease at the click of the mouse.[ 14 ] By linking each citation with a full reference, they ensure each citation in the text is accounted for by a corresponding full reference in the list.[ 12 ] Most of them are compatible for use with common programs such as Microsoft Word and Google Docs.[ 24 ]

There are numerous programs for reference management available in the market – independent applications, those operating within an internet interface, and combination of both these modes.[ 1 ] The most commonly used are Mendeley by Elsevier ( www.mendeley.com ), EndNote ( www.endnote.com ) by Thomson Reuters, and Zotero ( www.zotero.org ).[ 1 ] Some others are RefWorks, F1000 Workspace, JabRef, Citavi, Bibsonomy, ReadCube Papers, Colwiz, Sente, RefME, Connotea, CiteULike, BibTeX, and Microsoft Word.[ 22 , 24 , 25 ] While many of them are free, some are fee based and require a (paid) subscription.[ 13 ]

Despite the use of RMS, one cannot guarantee absence of referencing errors, as there can be errors in details (author names, journal title, dates) or duplication of references when retrieved from different databases.[ 23 ] So, ultimately, the authors (themselves) are responsible for the accuracy of the references cited by them (whether they do the referencing using RMS or manually).

Thus, referencing is an essential part of research and should be assigned due importance, right from the conception of the study question till its delivery as a publication. It plays a vital role throughout the manuscript and appears in almost all sections – from laying down the foundation for study rationale (in the “Introduction” section of the manuscript), describing/justifying the study procedure/s (in the “Methods” section), validating the results (in the “Results” section) and its implications (in the “Discussion” section of the manuscript). References are also utilized by editors to identify subject experts for peer review, by readers to obtain more resources on the subject matter, and by peer reviewers to critically evaluate the manuscript in the light of the available evidence. It is thus essential that references are chosen wisely and carefully as they are representative of the study. It is the author's responsibility to confirm the clarity, accuracy, and appropriateness of the cited sources. One should be careful to avoid common referencing errors to prevent delay/rejection by the journal of interest. As Vancouver style is the commonly preferred citation style by journals of medicine and health sciences, researchers should be well versed with it. Authors should diligently stick to the instructions and style of the target journal. The availability of reference management software such as Mendeley and EndNote has made the authors’ task of collecting, storing, organizing, retrieving, and utilizing the references more efficient and easier; however, it is still the authors’ responsibility to select appropriate references and cite them accurately and correctly.

Charts and Graphs

Since the APA manual does not give direct information for citing every type of source, including charts or graphs, they instruct you to follow the example that is most like the source you are trying to cite. Be sure to provide enough information so your readers can locate the source on their own. When possible provide author or creator, year of publication, title, and publishing and/or retrieval data. When citing a chart, graph or map it may be best to follow the citation style for the format in which the information is presented.

All captions for charts should follow the guidelines below for captions for figures.

Captions for Figures (Charts, Graphs, and Maps): Publication manual of the American Psychological Association 5.20-5.25

All captions should be labeled as Figure followed by a number. The caption should begin with a descriptive phrase and include a citation to the original source and copyright information at the end.

Prevent plagiarism. Run a free check.

References are ordered alphabetically by the first author’s last name. If the author is unknown, order the reference entry by the first meaningful word of the title (ignoring articles: “the”, “a”, or “an”).

Word processors like Word or Google Docs and citation generators can usually order the reference list automatically. However, ordering becomes challenging when citing multiple works by the same author or works by authors with the same last name.

Our in-depth article on ordering references in APA Style explains what to do in these situations.

Only include references for sources cited in the body text (with an APA in-text citation ). Don’t include references for:

• Sources that you only consulted;
• Personal communications (e.g., emails or phone calls);

What Is Cite This For Me’s Reference Generator?

Cite This For Me’s open-access generator is an automated citation machine that turns any of your sources into references in just a click. Using a reference generator helps students to integrate referencing into their research and writing routine; turning a time-consuming ordeal into a simple task.

A referencing generator accesses information from across the web, drawing the relevant information into a fully-formatted bibliography that clearly presents all of the sources that have contributed to your work.

If you don’t know how to reference a website correctly, or have a fast-approaching deadline, Cite This For Me’s accurate and intuitive reference generator will lend you the confidence to realise your full academic potential. In order to get a grade that reflects all your hard work, your references must be accurate and complete. Using a citation machine not only saves you time but also ensures that you don’t lose valuable marks on your assignment.

Not sure how to format your citations, what citations are, or just want to find out more about Cite This For Me’s reference generator? This guide outlines everything you need to know to equip yourself with the know-how and confidence to research and cite a wide range of diverse sources in your work.

Why Do I Need To Reference?

Simply put, when another source contributes to your work, you have to give the original owner the appropriate credit. After all, you wouldn’t steal someone else’s possessions so why would you steal their ideas?

Regardless of whether you are referencing a website, an article or a podcast, any factual material or ideas you take from another source must be acknowledged in a citation unless it is common knowledge (e.g. Winston Churchill was English). Failing to credit all of your sources, even when you’ve paraphrased or completely reworded the information, is plagiarism. Plagiarising will result in disciplinary action, which can range from losing precious marks on your assignment to expulsion from your university.

What’s more, attributing your research infuses credibility and authority into your work, both by supporting your own ideas and by demonstrating the breadth of your research. For many students, crediting sources can be a confusing and tedious process, but it’s a surefire way to improve the quality of your work so it’s essential to get it right. Luckily for you, using Cite This For Me’s reference generator makes creating accurate references easier than ever, leaving more time for you to excel in your studies.

In summary, the citing process serves three main functions:

• To validate the statements and conclusions in your work by providing directions to other sound sources that support and verify them.
• To help your readers locate, read and check your sources, as well as establishing their contribution to your work.
• To give credit to the original author and hence avoid committing intellectual property theft (known as ‘plagiarism’ in academia).

How Do I Cite My Sources With The Cite This For Me Referencing Generator?

Cite This For Me’s reference generator is the most accurate citation machine available, so whether you’re not sure how to format in-text references or are looking for a foolproof solution to automate a fully-formatted bibliography, this referencing generator will solve all of your citing needs.

Crediting your source material doesn’t just prevent you from losing valuable marks for plagiarism, it also provides all of the information to help your reader find for themselves the book, article, or other item you are citing. The accessible interface of the reference generator makes it easy for you to identify the source you have used – simply enter its unique identifier into the citation machine search bar. If this information is not available you can search for the title or author instead, and then select from the search results that appear below the reference generator.

Don’t know how to reference a website? The good news is that by using tools such as Cite This For Me’s reference generator, which help you work smarter, you don’t need to limit your research to sources that are traditional to cite. In fact, there are no limits to what you can cite, whether you are referencing a website, a YouTube video or a tweet.

To use the reference generator, simply:

• Select your style from Harvard, APA, OSCOLA and many more*
• Choose the type of source you would like to cite (e.g. website, book, journal, video)
• Enter the URL , DOI , ISBN , title, or other unique source information to find your source
• Click the ‘Cite’ button on the reference generator
• Copy your new citation straight from the referencing generator into your bibliography
• Repeat for each source that has contributed to your work.

*If you require another style for your paper, essay or other academic work, you can select from over 1,000 styles by creating a free Cite This For Me account.

Once you have created your Cite This For Me account you will be able to use the reference generator to create multiple references and save them into a project. Use Cite This For Me’s highly-rated iOS or Android apps to generate references in a flash with your smartphone camera, export your complete bibliography in one go, and much more.

What Will The Reference Generator Create For Me?

Cite This For Me’s reference generator will create your citation in two parts: an in-text citation and a full citation to be copied straight into your work.

The reference generator will auto-generate the correct formatting for your bibliography depending on your chosen style. For instance, if you select a parenthetical style the reference generator will generate an in-text citation in parentheses, along with a full citation to slot into your bibliography. Likewise, if the reference generator is set to a footnote style then it will create a fully-formatted citation for your reference list and bibliography, as well as a corresponding footnote to insert at the bottom of the page containing the relevant source.

Parenthetical style examples:

In-text example: A nation has been defined as an imagined community (Anderson, 2006).* Alternative format: Anderson (2006) defined a nation as an imagined community.

*The reference generator will create your references in the first style, but this should be edited if the author’s name already appears in the text.

Bibliography / Works Cited list example: Anderson, B. (2006). Imagined Communities. London: Verso.

What Are Citation Styles?

A citation style is a set of rules that you, as an academic writer, must follow to ensure the quality and relevance of your work. There are thousands of styles that are used in different academic institutions around the world, but in the UK the most common are Harvard, APA and Oscola.

The style you need to use will depend on the preference of your lecturer, discipline or academic institution – so if you’re unsure which style you should be using, consult your department and follow their guidelines exactly, as this is what you’ll be evaluated on when it comes to marking. You can also find your university’s style by logging into your Cite This For Me account and setting your institution in ‘My Profile’.

Citing isn’t just there to guard against plagiarism – presenting your research in a clear and consistent way eases the reader’s comprehension. Each style has a different set of rules for formatting both the page and your references. Be sure to adhere to formatting rules such as font type, font size and line spacing to ensure that your work is easily legible. Furthermore, if your work is published as part of an anthology or collected works, each entry will need to be presented in the same style to maintain uniformity throughout. It is important to make sure that you don’t jump from one style to another, so follow the rules carefully to ensure your reference list and bibliography are both accurate and complete.

If you need a hand with your citations then why not try Cite This For Me’s reference generator? It’s the quickest and easiest way to cite any source, in any style. The reference generator above will create your citations in the Harvard referencing style as standard, but it can generate fully-formatted references in over 1,000 styles – including university variations of each style. So, whether your lecturer has asked you to adopt APA referencing , or your subject requires you to use OSCOLA referencing , we’re sure to have the style you need. To access all of them, simply go to Cite This For Me’s website to create your free Cite This For Me account and search for your specific style such as MLA or Vancouver .

How Do I Format A Reference List Or Bibliography?

Drawing on a wide range of sources greatly enhances the quality of your work, and reading above and beyond your recommended reading list – and then using these sources to support your own thesis – is an excellent way to impress your reader. A clearly presented reference list or bibliography demonstrates the lengths you have gone to in researching your chosen topic.

Typically, a reference list starts on a new page at the end of the main body of text and includes a complete list of the sources you have actually cited in your paper. This list should contain all the information needed for the reader to locate the original source of the information, quote or statistic that directly contributed to your work. On the other hand, a bibliography is a comprehensive list of all the material you may have consulted throughout your research and writing process. Both provide the necessary information for readers to retrieve and check the sources cited in your work.

Each style’s guidelines will define the terminology of ‘reference list’ and ‘bibliography’, as well as providing formatting guidelines for font, line spacing and page indentations. In addition, it will instruct you on how to order each list – this will usually be either alphabetical or chronological (meaning the order that these sources appear in your work). Before submitting your work, be sure to check that you have formatted your whole paper according to your style’s formatting guidelines.

Sounds complicated? Citing has never been so easy; Cite This For Me’s reference generator will automatically generate fully-formatted citations for your reference list or bibliography in your chosen style. Sign in to your Cite This For Me account to save and export your bibliography.

How Do References Actually Work?

Although the reference generator will create your bibliography for you in record time, it is still useful to understand how this system works behind the scenes. As well as saving you time with its referencing generator, Cite This For Me provides the learning resources to help you fully understand the citing process and the benefits of adopting great citing standards.

The referencing process:

• Find a book, journal, website or other source that will contribute to your work
• Save the quote, image, data or other information that you will use in your work
• Save the source information that enables you to find it again (i.e. URL, ISBN, DOI etc.)
• Format the source information into a citation
• Copy and paste the citation into the body of the text
• Repeat for each source that contributes to your work.
• Export or copy and paste the fully-formatted citation into your bibliography.

Which style should I use?

For PACE programmes guidance is provided below for a numbered style (Vancouver) and an author-year style (Harvard).  However you can use a different style as long as your references are clear and consistent.

If you are new to referencing and not familiar with using the more advanced features of word processing software, we advise using the Harvard format for longer assignments as it is easier to keep track of the placement and order of your references, but it will eat into your word count. The numbered Vancouver style is useful for shorter assignments but can become impractical for longer ones (unless using a reference management system like EndNote). 

Further support with writing references

• Chapters in edited books
• Journal articles
• British Pharmacopoeia
• NICE guidelines
• Local guidelines
• SmPCs/PILs on EMC
• Systematic reviews on the Cochrane Library
• Clinical trials
• Materials posted on Blackboard

Vancouver is a numbered style. Each piece of work cited should have a unique number, assigned in order (your first reference is 1, your second is 2 etc.). It is a very plain style with little punctuation and no text formatting such as italics, underlining or bold.

In-text citations

When adding an in-text citation to your document you can write the number in brackets:

Medical systems need to be carefully considered and designed to reduce the likelihood of medication errors (1).

How do I cite multiple sources together?

• When citing two or more sources at once, write a number for each separated by a comma e.g. (1, 2) or (6, 12)
• When citing more than two sources which are numbered consecutively, use a hyphen instead of a comma e.g. (3-5)

For example:

There are many studies that have examined the effect of alcohol on cognitive impairment (1,2, 4-7, 9).

Other citation questions

How should i refer to authors in the text.

You do not have to refer to the authors' names in the text but it may help the flow of your writing to do so.

Two authors: give both author's surnames linked with 'and'. For example:

A recent study by Chen and Lee (4) found that...

Three or more authors: use the first author's surname followed by "et al.". For example:

A recent study by Rang et al. (2) found that...

An organisation: give the full name with any recognised abbreviation in brackets afterwards e.g. National Institute for Health and Care Excellence (NICE). Thereafter you can refer to it using the abbreviation. Give the full name and abbreviation in the full reference. For example:

A survey by Asthma UK found that one in 20 people suffer from severe asthma (6).

How do I include a quote from a source?

If directly quoting from a work, you need to use single quotation marks. Include a page number in the in-text citation. For example:

More recently, a paper by Walker et al. (3) stated that 'student pharmacists are valuable and important to practice model transformation' (p. 47).

A paper by Walker et al.stated that 'student pharmacists are valuable and important to practice model transformation' (3, p. 47).

How do I refer to a source referenced in another work?

This type of referencing is known as secondary referencing and should be avoided wherever possible, as the author citing the work may have their own bias or misinterpretation. It is better to seek out the original reference (in this example, Ahmed’s) and cite it directly if it is useful.

You need to include both authors' names in the body of your text to show that you have not read the original article. In the final reference list, you should only include the reference you have read yourself (Jones in this example):

According to Ahmed as cited in Jones (5)...

Reference list

References must be listed at the end of your document in numerical order based on the order of citation.  If you use the same source more than once, the original citation number should be used. 

Author names

Cited by Surname Initials - there is no comma between the surname and initials, nor any full stop or space between initials.

Multiple authors

Authors should be listed in the order they appear on the publication. Only list the first six authors followed by et al. 

Monzer NL, Hartmann M, Buckert M, Wolff K, Nawroth P, Kopf S et al. 

Additional guidance

See the tabs in this box for additional guidance and relevant examples. Our Vancouver guidance is closely aligned with that given in the 'Cite them right' book and website (below). You can find extra publication types and examples via this website. Note that we deviate from this guide in some case to make references simpler. For instance you should put journal names in full not abbreviated.

Citing books and e-books

Most books and e-books can be cited in the same way. If you are viewing the PDF of a printed book there is no need to include the web address in your reference if you have the place published and publisher.

Include the following in your reference:

• Author(s) or editors in the format Surname Initials (no full stops or spaces between initials). For books with more than six authors list the first six followed by 'et al.'
• Title of book (capitalise only the first letter of the first word and any proper nouns)
• Edition (if not the first)
• Place of publication: Publisher; Year. You can usually find this information on the title page or following page.

Copy the format and punctuation of these examples:

• Ritter JM, Flower RJ, Henderson G, Loke YK, MacEwan D, Robinson E, Fullerton J. Rang & Dale's pharmacology. 10th ed. London: Elsevier; 2024.
• Ashley C, Dunleavy A, editors. The renal drug handbook: the ultimate prescribing guide for renal practitioners. 5th ed. Boca Raton: CRC Press; 2019.

Citing online only books

Some books are born digital and are not published in a traditional format. If the book does not have a Place published and Publisher then you will need to follow this guidance. Include the following in your reference:

• Author(s) or editors in the format Surname Initials (no full stops or spaces between initials) For books with more than six authors list the first six followed by 'et al.'
• Year. 
• [cited year month day] - the date you looked at it e.g. [cited 2022 Jun 18] You can usually find this information on the title page or following page.
• Available from: https://doi.org... or web address

Note: if you are unable to find a place published and publisher you will need to cite the item following the web page guidance.

• UK Health Security Agency. Immunisation against infectious disease (The Green Book) [Internet]. 2021 [cited 2024 Jan 26]. Available from: https://www.gov.uk/government/collections/immunisation-against-infectious-disease-the-green-book.

Note: Using StatPearls? Follow the guidance on citing an online only book chapter .

EndNote tips

• Use the Reference Type 'Book'
• Author: in the format surname, initials, each author on a separate line
• Place published:
• Edition: if not the first - just add the number e.g. 2nd, 3rd
• Use the Reference Type  'Edited book'
• Same as above but instead of the Author field fill in the Editor field 
• Use the Reference Type 'Electronic Book'
• Type of Medium: Internet
• Year Cited: in the format 2024
• Date Cited: in the format month day e.g. Jan 23
• URL: paste in the web link
• Note that even with the information entered as above EndNote will not quite format the reference correctly - the edition will not appear and for edited e-books 'editors' will not be added after the editor names. To correct this, as a final step before submission, create a plain text version of your document. Go to the EndNote toolbar in Word and select 'Convert citations and bibliography' to 'Plain text' (this will be under 'Tools' on the Mac version of the toolbar). This will create a copy of your document which is divorced from EndNote so that you can make final tweaks to the references to match the guidance above.

Citing chapters in printed books and e-books with publication details

Follow this guidance to cite a printed book or an e-book which has the publisher and place published information. Include the following in your reference:

• Chapter author(s) in the format Surname Initials (no full stops or spaces between initials)
• Title of chapter. (capitalise only the first letter of the first word and any proper nouns)
• Editor(s) of the book followed by , editors
• Title of book. (capitalise only the first letter of the first word and any proper nouns)
• Place of publication: Publisher; Year.
• Page numbers of the chapter preceded by p. Abbreviate where appropriate e.g. 110-128 would be 110-28, 450-455 would be 450-5.

Citing chapters in online only books

Some books are born digital and are not published in a traditional format. When citing chapters in these include the following in your reference:

• Chapter author(s) in the format Surname Initials  (no full stops or spaces between initials)
• Title of chapter. (capitalise only the first letter of the first word and any proper nouns)
• [cited year month day] - the date you looked at it e.g. [cited 2022 Jun 18]
• Page numbers of the chapter if available preceded by p. Abbreviate where appropriate e.g. 110-128 would be 110-28, 450-455 would be 450-5.

Endnote tips

• Use the Reference Type 'Book Section'
• Author(s): in the format surname, initials. Each author on a separate line.
• Title: title of chapter 
• Editor(s): in the format surname, initials. Each editor on a separate line.
• Book title: capitalise only the first letter of the first word and any proper nouns
• Pages: page numbers for the chapter
• Use the Reference Type 'Electronic Book Section'
• Title: chapter title
• Editor: (if there is one)
• Book Title:
• Type of Work: Internet
• Access Date: in the format year, month (abbreviated to three letters) day e.g. 2024 Jan 21
• Note that even with all the required information entered in EndNote it will not format the reference correctly - the Edition and Type of Work will not be in the correct place. For edited e-books 'editors' will not be added after the editor names. The Access Date will be repeated at the end. To correct this, as a final step before submission, create a plain text version of your document. Go to the EndNote toolbar in Word and select 'Convert citations and bibliography' to 'Plain text' (this will be under 'Tools' on the Mac version of the toolbar). This will create a copy of your document which is divorced from EndNote so that you can make final tweaks to the references to match the guidance above.

Note that the way you enter a chapter on EndNote for the Vancouver style is different from the way you enter it for the Harvard style. It is not possible to reuse one entry in both styles.

Citing journal articles which have page numbers or article reference numbers

• Article author(s) in the format Surname Initials (no full stops or spaces between initials). For articles with more than six authors list the first six followed by 'et al.'
• Title of article. (capitalise only the first letter of the first word and any proper nouns)
• Journal title in full (use a capital letter at the start of each significant word in the title) Note: we are not following the 'Cite them right' guidance to abbreviate journal names.
• Volume number
• Issue number in brackets (where present)
• Page numbers or article reference number. Abbreviate page ranges where appropriate e.g. 110-128 would be 110-28, 450-455 would be 450-5.

Copy the format and punctuation of this example:

Citing online journal articles without page numbers or article reference numbers

• Article author(s) in the format Surname Initials (no full stops or spaces between initials). For articles with more than six authors list the first six followed by 'et al.'
• Available from: https://doi.org/... or web address if no DOI. When including a web address make sure it is as short as possible and doesn't include intermediate websites or your search string.

You should be able to download details for most articles from databases such as Summon, Web of Science, Scopus and PubMed. If you need to type one in from scratch this is the information to include.

For most articles

• Use the Reference Type 'Journal Article'
• Author: in the format surname, initials - each author on a separate line
• Title: title of the article - in lower case apart from the first letter of the first word and any proper nouns
• Journal: name of the journal - give the journal name in full, not abbreviated. Use initial capital letters on all significant words.
• Issue: (if present)
• Pages: page numbers or article reference number

For online only articles without page numbers or an article reference number and 'In press' articles:

• Use Reference Type 'Electronic Article'
• Periodical Title: name of the journal - give the journal name in full, not abbreviated. Use initial capital letters on all significant words.
• Volume: (if the article doesn't yet have a volume number add 'Forthcoming ' before the year - as in the above example)
• Issue: (put in press here for articles currently being published).
• Date Cited in the format month day e.g. Feb 5.
• URL: paste in the web link for the article or move the DOI from the DOI field and add https://doi.org/ in front of it e.g. https://doi.org/10.1136/ejhpharm-2021-003215 If there is already a URL in the box check that it goes to the article, not back to the reference on the database you downloaded it from. Replace any database links with the DOI with https://doi.org/ in front of it or add the direct link to the article. When including a web address make sure it is as short as possible and doesn't include intermediate websites or your search string. 

Citing websites or webpages

You should avoid citing webpages unless you are clear of their quality and suitability for inclusion in academic work. See the 'Websites' tab within this guide for more information on evaluating webpages.

Only follow this guidance if the item you want to reference is not a book, a book chapter or a journal article.  When you search the internet you will find many different types of content. The first step to referencing correctly is to recognise what you are looking at.

• Could it be a book? Is it a PDF? Does it have a title page giving the title and the authors/editors? Does it have a place published and publisher on the following page? If 'Yes' it is probably a book - follow the guidance on citing a book.
• Could it be a book chapter? Does it say 'Chapter' on it? Does it have page numbers? If 'Yes' it could be a book chapter - follow the guidance on citing a book chapter.
• Could it be journal article? Does it have an abstract or summary? Does it mention the name of a journal and have a volume number? If 'Yes' it could be a journal article - follow the guidance on citing a journal article.

For guidance on citing specific, commonly used pharmacy-related sources see the other tabs in this box.

Citing reputable websites and webpages

• Author(s)/Organisation name
• Title of page/document (capitalise only the first letter of the first word and any proper nouns)

Citing materials posted on Blackboard

Always check with the academic who set the assignment if you are allowed to refer to course materials in your own work. It is preferable to do your own research and use published sources, such as articles and books, instead of referring to lecture materials.

• Author's name in the format Surname Initials
• Title of document/presentation as given on Blackboard
• Format in square brackets e.g. [PowerPoint presentation, Lecture notes, Recorded lecture, Handout]
• Place of publication:
• Institution;
• Course details, date
• [cited year month day] - the date you looked at it e.g. [cited 2024 Jan 18]
• Available from: https://www.bb.reading.ac.uk Note that you do not need to give the specific web address for the material you are citing. The address for Blackboard is sufficient.

Copy the format and punctuation of these examples.

Example 1: PowerPoint slides

Cottrell G. The molecules of life: proteins [PowerPoint presentation]. Reading: University of Reading; PM1PY2: Fundamentals of Cell Biology; 2023 [cited 2023 Dec 2]. Available from: https://www.bb.reading.ac.uk.

Example 2: Handout with no date

University of Reading. Direct observation of procedural skills (DOPS) assessment form [Handout] Reading: University of Reading; PM2PY1: Professional Practice 2. [cited 2023 Nov 30]. Available from: https://www.bb.reading.ac.uk.

• Use the 'Web Page' Reference Type
• Place published: Reading
• Publisher: University of Reading
• Type of Medium: add the Format here e.g. PowerPoint presentation, Lecture notes, Recorded lecture, Handout
• Contents: module code and title e.g. PM2PY1: Professional Practice 2
• Date Cited: in the format month day e.g. Jan 20
• URL: https://www.bb.reading.ac.uk

Note that even with the information entered as above EndNote will not quite format the reference correctly - the module details will be in the wrong place. To correct this, as a final step before submission, create a plain text version of your document. Go to the EndNote toolbar in Word and select 'Convert citations and bibliography' to 'Plain text' (this will be under 'Tools' on the Mac version of the toolbar). This will create a copy of your document which is divorced from EndNote so that you can make final tweaks to the references.

Harvard referencing - click on the tabs for guidance on specific publications

• Video guide to Harvard
• Systematic reviews on The Cochrane Library

The 'Cite Them Right' Harvard style is an author-date system. In-text citations include the author and year of the reference. Full references are listed at the end in alphabetical order by the author's surname. See the other tabs in this box for guidance on citing specific types of publication in this style.

For the Harvard style, your in-text citation should include:

• The author of the cited work
• The year of publication of the cited work.

There are two ways of including an in-text citation and you can use both depending on how you want to structure each sentence. You can include the citation with the author’s surname and date in brackets at the end of the sentence:

Medical systems need to be carefully considered and designed to reduce the likelihood of medication errors (Ferner, 2020).

Or, you can include the author’s surname as part of your sentence, in which case only the date is in brackets:

More recently, a paper by Ferner (2020) has suggested that...

You can use a mix of these approaches in your assignment.

How many authors do I need to include in the in-text citation?

If the citation has two authors.

List both authors with 'and' or '&' in between (but be consistent in your use of 'and' or '&').

A recent study by Morbey and Smith (2021) found that...

... (Morbey and Smith, 2021) .

If the citation has three authors

List all three authors with a comma after the first author, '&' or 'and' before the last author (but be consistent in your use of 'and' or '&').

A recent study by Chen, Savana and Patel (2022) found that...

... (Chen, Savana and Patel, 2022) .

If the citation has four or more authors

Use the first author's name followed by " et al. " in italics.

A recent study by Rang et al. (2020) found that...

It has been shown previously (Rang et al. , 2020) that....

Note: you will need to include ALL authors in the full reference at the end of your document.

How do I cite more than one source for a sentence?

List the sources chronologically, separated by semi-colons.

There are many studies that have examined the effect of alcohol on cognitive impairment (Chen and Xi, 2012; Patel, 2020; Hussein et al ., 202 2) .

How do I differentiate references by the same author in the same year?

Differentiate them using letters after the year - both in the in-text citation and the full reference.

Chen and Hussein (2021a) ... and Chen and Hussein (2021b) ...

Can I cite a work by a company or organisation?

Many works by organisations do not have individually named authors. In this case, you can use the name of the organisation or company, such as Cancer Research UK or National Institute for Health and Care Excellence (NICE), as the author. This is known as a corporate author. 

Asthma UK (2015) studies have shown...    ...  (Asthma UK, 2015) .

What if I have multiple references by the same author in a sentence?

If you need to refer to two or more sources by the same author in different years, you do not need to keep repeating the author's surname in the citation. Include the surname and the oldest year first, then separate the other years by semicolons (;). The sources should be ordered by year of publication, with the oldest first.

NHS (2016; 2019; 2021) studies have consistently shown    ... (NHS, 2016; 2019; 2021)

You must include all of the sources separately in your reference list.

Do I need to include page numbers in my citation?

You only need to include a page number if directly quoting from a work. Enclose the quote in single quotation marks and include a page number in the in-text citation. For example:

More recently, a paper by Walker et al. (2020) stated that 'student pharmacists are valuable and important to practice model transformation' (p. 47) .

A recent paper stated that 'student pharmacists are valuable and important to practice model transformation' (Walker et al.,  2020, p. 47) .

This type of referencing is known as secondary referencing and should be avoided wherever possible , as the author citing the work may bring their own bias or misinterpretation. It is better to seek out the original reference and cite it directly if it is useful.

See further guidance on secondary referencing .

References must be listed at the end of your document in  alphabetical order by author surname/organisation name.  If you use the same source more than once, just use the same in-text citation as previously to refer to the same full reference. 

Cited using Surname, Initials - place a comma and a space between the surname and initials. Full stops between initials e.g.:

List all of the authors in the full reference in the order they appear on the publication.

See the tabs in this box for additional guidance and relevant examples. Our Harvard guidance is closely aligned with that given in the 'Cite them right' book and website (below). You can find extra publication types and examples via this website. Note that we deviate from this guide in some case to make references simpler e.g. only requiring DOI or web address for articles which do not have page numbers or an article reference number.

• Use the Reference Type  'Book Section'
• Author: in the format surname, initials. Each author on a separate line.
• Editor: (include all the editors in the format surname, initials. Each editor on a separate line)
• Book title:
• Pages: page numbers for the chapter e.g. 301-335
• Complete the details above (as much as possible)
• Add URL: paste in the web link
• Add Access Date: the date you looked looked at the book in the format day month year e.g. 3 February 2024

Note that the way you enter an online only chapter on EndNote for the Harvard style is different from the way you enter it for the Vancouver style. It is not possible to reuse one entry in both styles.

Note that the default 'Cite Them Right Harvard' style in EndNote does not handle e-book sections very well. Download and use our amended style which corrects these issues:

• Reading Cite Them Right Harvard style Once downloaded open the style and go to 'File' and 'Save as' and 'Save'. This should save it into a location where EndNote can find it and use it. You will then need to select the 'Reading Cite Them Right-Harvard' style from the list of styles in Word (click on 'Select another style' to find it).

Alternatively as a final step before submission, create a plain text version of your document. Go to the EndNote toolbar in Word and select 'Convert citations and bibliography' to 'Plain text' (this will be under 'Tools' on the Mac version of the toolbar). This will create a copy of your document which is divorced from EndNote so that you can make final tweaks to the reference to match the guidance above.

• ALL Author name(s) in the format 'Surname, Initials'
• Year of publication (in brackets)
• Article title - in lower case apart from the first letter of the first word and any proper nouns

For guidance on citing other types of materials posted on Blackboard see Section G7 of the following book:

• Use the Reference Type  'Web Page' 
• Series title: module code and title
• Access Date: date you looked at it in the format day month year e.g. 25 January 2024
• Type of Medium: add the Format here e.g. Presentation slides, Lecture notes, Recorded lecture, Handout
• URL: https://www.bb.reading.ac.uk 

Note that even with the information entered as above the default 'Cite Them Right-Harvard' style in EndNote will not quite format the reference correctly - the title of the document should be enclosed in single quotes and be in plain text; the module details should be in italics; there should be closing bracket after the access date; the Type of Medium should be after the document title. To correct this, as a final step before submission, create a plain text version of your document. Go to the EndNote toolbar in Word and select 'Convert citations and bibliography' to 'Plain text' (this will be under 'Tools' on the Mac version of the toolbar). This will create a copy of your document which is divorced from EndNote so that you can make final tweaks to the references.

Secondary referencing (citing a source you have read about in a different source)

A secondary reference is used when you are referring to a source which you have not read yourself, but have read about in another source.  Where possible, you should always try to read the original of anything you wish to refer to ; otherwise you are relying on the author who cited the reference to have interpreted it correctly and not taken it out of context. Use the reference list at the end of the source you are reading to find details of the reference and search for it using the search boxes below.

Find books using the Enterprise catalogue

Just type in the first author's surname and a few words from the title.

Find journal articles using Summon

Just type in the first author's surname and first part of the article title.

If you can't get hold of the original source you'll need to do a secondary reference and you should make clear that you are not using the original source. Only include the source you have used in your list of references following the guidance above on citing that type of publication. Indicate in your in-text citation that it is a secondary reference by preceeding the citation with 'as cited in' or 'as quoted in'.

Vancouver example

In-text citation:

According to France as cited in Weingart et al. (4) , hospitals use internal reporting procedures to identify...

4. Weingart, SN, Zhang L, Sweeney M, Hassett M. Chemotherapy medication errors. The Lancet Oncology, 2018; 19(4): e191-e199.

Harvard example

According to France (2003, as cited in Weingart et al. , 2018), hospitals use internal reporting procedures to identify...

Reference: 

Weingart, S.N., Zhang, L., Sweeney, M, & Hassett, M. (2018) 'Chemotherapy medication errors',  The Lancet Oncology , 19(4), pp. e191-e199.

Vancouver - just edit your text as in the example above and insert the reference for the paper you have read in the usual way.

• Insert the in-text citation for the paper you have read in the usual way.
• Right-click on the in-text citation and select ' Edit Citation(s) ' and ' More... '. 
• In the prefix box type the year of the paper you haven't read followed by a comma and space and 'as cited in ' (as in the example above). Click OK.
• In front to the in-text citation type in the author name(s) for the paper you haven't read (as in the example above), including the correct number of authors.

Citing tables, figures & images

Images, graphs, charts, diagrams and tables that you have used from books, websites and other texts should be referenced in the same way that you would any other material.

The captions for both tables and figures should include a citation if taken from or based on another source (name-year or number depending on the style you are using). When you refer to it in your writing, use the figure/table number. Give a full citation in the reference list for the source of the image.

Citing tables

Tables should be sequentially numbered with the title/legend above the table - as in this example which uses the Harvard referencing style:

Example of referring to a table in a sentence:

The macronutrient content of the diets used in the study is shown in Table 2. 

Full details for reference list (Harvard style):

(eds)  Cardiovascular disease in racial and ethnic minority populations . Cham: Humana Press, pp. 167-182.

Citing figures (images, graphs and diagrams)

Images, graphs and diagrams should be labelled as 'Figure' and sequentially numbered with the caption below - as in this example which uses the Harvard referencing style:

Example of referring to a figure in a sentence:

The prebiotics can induce direct or indirect effect on the gut-associated epithelial and immune cells (Figure 3).

Pujari, R. and Banerjee, G. (2021) 'Impact of prebiotics on immune response: from the bench to the clinic',  Immunology and Cell Biology , 99(3), pp. 255-273.

Decorative images

If the image is purely decorative you should still acknowledge the creator and source but there is no need to include a full reference.

See the example on the right which includes the caption: 'Image: [creator] via [website image captured from]'.

If it is a picture you have taken use this format:

'Image by author'.

Compiling your own table from multiple sources

If you are taking information from multiple sources and compiling your own table you still need to acknowledge those sources. 

The following link shows two ways of doing this. Although this is a guide to using the APA style the approaches can be adapted for use with Harvard and Vancouver.

• How to cite sources in a table (APA)

Quotes and copying information

• Copying information
• Example 1 (prose)
• Example 2 (standards)
• When taking information from a reference source which you are not putting into your own words i.e. copying and pasting you need to put quotes around the words to indicate that it is not your own work
• Students are expected to put the majority of information into their own words to demonstrate their understanding and independent thought - the amount of information in quotes should therefore be minimal
• Quotes should be reserved for situations where no alternative wording is possible and/or where it is not appropriate (e.g. quoting a standard or particular statement which supports your argument)
• Wenger (1, p. 181) argues that 'Engagement, imagination and alignment each create relations of belonging'.
• The focus of Wenger's discussion is on the way that different aspects come together to build notions of identity (1).
• Theorists have considered the impact of a variety of circumstances on the creation and expansion of identity (1-3).

Avoid quoting large blocks of text:

The NICE guidance for hypertension (1) states the following:

'Beta-blockers are not a preferred initial therapy for hypertension. However, beta-blockers may be considered in younger people, particularly:

• those with an intolerance or contraindication to ACE inhibitors and angiotensin II receptor antagonists or
• women of child-bearing potential or
• people with evidence of increased sympathetic drive'

Instead this could be paraphrased as:

NICE no longer recommend beta-blockers to be used as initial therapy for hypertension, although it is recognised that there may be circumstances in which younger patients may benefit from beta-blockers (1).  In my practice I may review younger patients, therefore I will consider the recommendations from NICE on appropriate prescribing of beta-blockers, for example women of child-bearing age, patients with increased sympathetic drive or unable to take ACE inhibitors and angiotensin II receptor antagonists.

Consider using a reference management system such as EndNote to help you reference correctly. This bibliographic management package can be used to store references, and then insert the citation in your Word document, automatically building the reference list for you in the correct style (''Vancouver' or Cite Them Right-Harvard').

Reading Scholarly Articles: Step-by-Step

1. Read the Abstract Section

The first step in reading a scholarly article is to read the abstract or summary of the article. Abstracts are always found at the beginning of an article and provide a basic summary or roadmap to the article. The abstract also introduces the purpose of the article.

Take a few minutes to carefully read the abstract of the practice article. Note that the abstract is not formally labeled "abstract" but is called "background and aims." Any summary at the start of an article is considered the abstract.

The abstract should always be read first to make sure the article is relevant to your topic. However, reading the abstract should never replace reading the entire article as the abstract is too brief to be used to fully understand the article.

2. Read the Conclusion Section Reading the conclusion will help you understand the main points of the article and what the authors are attempting to prove. 

3. Read the Introduction Section Now that you have an overview of the article from the abstract and understand the main points the authors are trying to prove from the conclusion, you will want to read the introduction.

4. Read the Results Section

Read the results section. Here are a couple of suggestions for deciphering results:

• If you are a visual learner, the charts may make sense to you.
• If charts are difficult to understand, look over the narrative and then return to the charts.
• Using the charts can help enhance your understanding of the narrative
• Look for works like "important" or "significant" and make special note of these phrases as these usually are signals from the author of an important result.

5. Read the Methods Section Reading the methods section will help you understand how the study or experiment was conducted. It is necessary for other researchers to understand the methods used so that they can replicate the study.

The methods section can also be difficult to read due to technical language used and density of the section. Try circling words, acronyms, and surveys you are unfamiliar with and look them up as those may be important to fully understand the article and may be necessary for future research. 

6. Read the Discussion & Limitations Section

The discussion section is where you will find the researcher's interpretation of the results. The author should answer the article's research question. Remember, you should evaluate the data to form your own conclusions. Don't just accept the author's conclusions without looking at the data for yourself.

Often authors will include a section detailing the limits to their research and their conclusions. The limitation section will usually explain conclusions that could not be drawn from the research as well as areas that future research is needed.

7. Read Through One More Time  After you have jumped around and read the different sections of the article, go back to the beginning and read the article in order. The article should be easier to read and make more sense as you will already be familiar with the main points in each section.

How to Start a Research Paper: A Step-by-Step Guide

Starting a research paper can seem overwhelming, but breaking it down into manageable steps can make the process much easier. This guide will walk you through each stage, from choosing a topic to finalizing your paper, ensuring you stay organized and focused. Whether you're new to research or looking to improve your skills, these steps will help you create a strong, well-structured paper.

Key Takeaways

• Select a topic that interests you and has enough available resources.
• Formulate a clear and focused research question to guide your study.
• Conduct a thorough literature review to understand existing research and identify gaps.
• Develop a detailed research plan with a timeline and methodology.
• Ensure proper formatting and citation to maintain academic integrity.

Choosing a Research Topic

Choosing a research topic is a crucial first step in writing a research paper. It sets the stage for your entire project, so it's important to choose wisely. Here are some steps to help you select a topic that is both interesting and feasible.

Identifying Your Interests

Start by thinking about what excites you. Pick a topic that you find fun and fulfilling. This will keep you motivated throughout your research. Make a list of subjects you enjoy and see how they can relate to your field of study. Your job will be more pleasant if you choose a topic that holds your interest.

Evaluating the Scope of the Topic

Once you have a few ideas, check if they are too broad or too narrow. A good topic should be manageable within the time you have. Ask yourself if you can cover all aspects of the topic in your thesis. For example, exploring the link between technology and mental health could be narrowed down to how WhatsApp use impacts college students' well-being.

Ensuring Availability of Resources

Before finalizing your topic, ensure that there are enough resources available. Conduct preliminary research to see if there is sufficient data and literature on your chosen topic. This step is vital as you may discover issues with your original idea or realize you have insufficient resources to explore the topic effectively. This key bit of groundwork allows you to redirect your research topic in a different, more feasible, or more relevant direction if necessary.

Formulating a Research Question

Understanding the importance of a research question.

A well-defined research question is the cornerstone of any successful research paper. It provides a clear focus and direction for your study, ensuring that your efforts are both relevant and meaningful. A strong research question helps you stay on track and avoid unnecessary detours. It also makes it easier to communicate the purpose and significance of your research to others.

Techniques for Crafting a Strong Research Question

To develop a compelling research question, start by identifying your interests and the gaps in the existing literature. Use the 5 W's: who, what, where, when, and why , to explore different aspects of your topic. This approach will help you narrow down your focus and create a question that is both specific and researchable. Additionally, consider the feasibility of your question by evaluating the availability of resources and the scope of your study.

Aligning Your Question with Objectives

Your research question should align with the objectives of your study. This means that it should be directly related to what you aim to achieve through your research. Clearly defined objectives will guide your research process and ensure that your question remains relevant throughout your study. By aligning your question with your objectives, you can produce a coherent and focused research paper that effectively addresses the problem at hand.

Conducting a Literature Review

Gathering Relevant Sources

Start by collecting sources that are related to your research topic. Use libraries, online databases, and academic journals to find books, articles, and papers. Skimming sources initially can save you time; set aside those that seem useful for a more thorough read later.

Analyzing Existing Research

Once you have gathered your sources, read through them carefully. Take notes on key points and different viewpoints. This will help you understand the current state of research in your field. Look for common themes and debates that can inform your own work.

Identifying Research Gaps

As you analyze the existing research, look for areas that haven't been explored or questions that haven't been answered. These gaps can provide a direction for your own research and make your thesis more valuable. Identifying these gaps is crucial for crafting a strong research question and ensuring your work contributes new knowledge to the field.

Developing a Research Plan

Creating a solid research plan is crucial for the success of your thesis. It helps you stay organized and ensures that you cover all necessary aspects of your research.

Writing the Thesis Introduction

Establishing context.

Starting your thesis introduction can be daunting, but it's crucial for setting the stage for your research. Establishing the context for your study helps readers understand the background and significance of your work. This section should provide a clear overview of what your thesis will cover, making it easier for readers to follow your arguments.

Crafting a Thesis Statement

Your thesis statement is the heart of your introduction. Typically, it is placed at the end of the introductory paragraph. This statement should succinctly present the main argument or focus of your thesis, guiding the reader on what to expect.

Justifying the Research Problem

Once you have your research question, you need to justify why it is important. Explain the significance of your research problem in the context of existing literature. Highlight the gaps your research aims to fill and how it will contribute to the field. This step is crucial for crafting a bachelor thesis that stands out.

Structuring the Research Paper

Organizing sections.

A well-structured research paper is essential for clarity and coherence. Start by dividing your paper into key sections: Introduction, Literature Review, Methodology, Results, Discussion, and Conclusion. Each section should serve a specific purpose and contribute to the overall argument of your paper. Organize your research by identifying main topics and subtopics, gathering relevant sources, and summarizing key points. This will help you maintain a logical flow throughout your paper.

Ensuring Logical Flow

Ensuring a logical flow between sections and paragraphs is crucial. Use transitions to connect ideas and guide the reader through your arguments. Each paragraph should begin with a clear topic sentence that introduces the main idea, followed by supporting evidence and analysis. This approach not only enhances readability but also strengthens your argument.

Maintaining Coherence

Coherence is achieved when all parts of your paper work together to support your thesis statement. To maintain coherence, make sure each section and paragraph aligns with your research objectives. Regularly review your work to ensure that your ideas are presented logically and that your voice remains dominant. Cite sources carefully to avoid plagiarism and to give credit to the original authors.

Data Collection and Analysis

Choosing data collection methods.

Selecting the right data collection methods is crucial for the success of your research. Data collection is the process of gathering, measuring, and analyzing accurate data. Consider methods such as surveys, interviews, or experiments based on your research needs. Each method has its strengths and weaknesses, so choose the one that best fits your study.

Analyzing Data Accurately

Once you have collected your data, the next step is to analyze it accurately. Use statistical tools and software to help you interpret the data. Create tables and graphs to illustrate your findings clearly. This will help you present your results in a structured and understandable way.

Interpreting Results

Interpreting your results is an essential part of your thesis. Discuss how your findings relate to your research questions and the existing literature. Highlight the significance of your analyses and the reliability of your findings. This will help you draw meaningful conclusions and provide valuable insights into your research topic.

Drafting and Revising the Paper

Writing the First Draft

Start by writing your first draft without worrying too much about perfection. Focus on getting your ideas down on paper. This initial draft is your chance to explore your thoughts and structure your argument. Remember, the goal is to create a foundation that you can build upon.

Incorporating Feedback

Once you have a draft, it's time to incorporate feedback. Share your work with your thesis supervisor and peers. Their insights can help you see your work from different perspectives and identify areas for improvement. Revising is a continuous process of re-seeing your writing. It involves considering larger issues like focus, organization, and audience.

Polishing the Final Draft

Finally, polish your final draft. Pay attention to grammar, punctuation, and formatting. Ensure that your thesis is clear, concise, and free of errors. This step is crucial for making a strong impression and effectively communicating your research findings.

Proper Formatting and Citation

Adhering to style guides.

When formatting your research paper, it's crucial to follow the specific style guide recommended by your institution. Common styles include APA, MLA, and Chicago. Each style has its own set of rules for formatting headings, tables, and references. Adhering to these guidelines ensures your paper meets academic standards and is easy to read.

Citing Sources Correctly

Citing your sources correctly is essential to avoid plagiarism and give credit to the original authors. Typically, a citation can include the author's name, date, location of the publishing company, journal title, or DOI (Digital Object Identifier) . Use the citation style specified by your university, such as APA or MLA . For example, in APA format, an in-text citation might look like this: (Smith, 2020).

Avoiding Plagiarism

Plagiarism is a serious academic offense. To avoid it, always cite the sources you use in your research. This not only gives credit to the original authors but also adds credibility to your work.
