Citation is necessary while writing your school essay, a publication, or a Master’s thesis. We all want our efforts to be acknowledged, right? The lack of references and citations can make the source think you are trying to steal their work. Hence, the question is how to go about making references.

Do you want to learn how to cite in a research paper? Then this article is for you, as it contains the details of how to reference when writing a research paper. There is a standard way to do this in educational journals and organizational publications.

Hence, a researcher must understand how to reference their writings or journals. It is another thing to write a journal properly, but crediting the sources is more crucial.

Follow this guide to learn:

• The importance of referencing and citations for your academic works;
• How to cite in APA, MLA, Chicago, IEEE, and ASA styles;
• Essential guidelines to follow for a published work.

Why Referencing and Citation Matter

Another important question is: What is the need for referencing and citation? The major reason for citations in research paper format is to serve as directional cues for the employed knowledge. When you cite, readers can know that some portions of your content belong to you. Hence, it is easier to identify how recent the information is.

Citation for your paper comes with several advantages. They include:

Academic Integrity

The citation affirms the integrity of your academic writing. In this information age, there are several details, and it can be difficult to authenticate. When you reference, it helps readers understand the necessity of the discussed topic. Referencing certain authors can give more authority to your papers.

Avoiding Plagiarism

Plagiarism refers to the mindless lifting of details from another material without acknowledging the details. For the source, they could believe you are stealing from them. In most countries, copyright infringement is a punishable crime and can make you lose your hard work.

Building Credibility

Credibility is the goal of every academic scholar. There is no better way to gain relevance than by citing sources from other credible ones.

Facilitating Further Research

For other researchers like you, providing citations can serve as other sources for more information. It helps them to know other philosophies about the subject.

Choosing the Right Citation Style

Now that the advantages have been established, the new worry is the choice of the right style. There are several styles with their respective peculiarities. For example, the MLA writing style is common in liberal scientific paper citations. Let’s delve more into MLA formatting for research papers and other styles.

APA (American Psychological Association)

The commonest style used by many scholars is APA formatting , especially if there is no stated style. This approach employs the use of in-text citations to explain the source. It’s the simplest form of citation.

Here is an in-text referencing example:

“Exercise is a good way to recover from ailments.” APA, n.d. (American Psychological Association).

The reference style includes:

• The author’s name;
• The author’s name is in parenthesis to follow the referenced excerpt;
• The publication date.

MLA (Modern Language Association)

MLA-style formation is concise and known for its scientific referencing format. The peculiarity of the MLA citation is its source citation, episode title, and document layout. You have to:

• Include the parenthetical citation;
• Create some spaces away from the left margin;
• Include the author’s or source’s name.

Ensure you capitalize every word when including the names. You can employ professional MLA Citation Generators to make the compilation easier. It is perfect for the citation format of scientific papers.

Chicago Style

Chicago’s style is famous for two things:

• The in-text citation within the paper;
• The reference list is at its end.

It is an author-date approach. Hence, the in-text citation for a research paper has the author’s or source name and publication year.

IEEE (Institute of Electrical and Electronics Engineers)

This employs the use of numbers. It is chronological as it arranges the citation based on the order of appearance. A click on it takes the reader to the full reference at the end of the paper. To make it easier, you can employ IEEE Citation Maker for a well-curated task. This way, you won’t have to worry about the manual compilation of the IEEE citation style.

This is similar to the author-date approach by Chicago Style. You can:

• Create the quotation;
• Include the parentheses for the author’s name and publication date;
• Add the page number using a colon.

Components of a Citation

Do you want to know how to complete a citation for your professional research paper writing service and research paper? Learn about its components.

The author is also regarded as the source. It is the original writer of the material you are referencing. Sometimes, there may be multiple authors. Do not miss out on anyone while citing a research paper.

Title of the Source

The title of the source is often the name given to the material by the author.

Publication Date

As the name implies, this refers to the date the source was published. Frequently, most writers include it at the start of their material. State the exact month and year of publication, separated with a comma. See example:

“(2016, March 7).”

Including the publisher’s details is only necessary for the full reference. It should be at the end of the paper. It can facilitate further research.

Page Numbers

The page number is necessary, as it helps to easily refer to different sections of the paper.

DOI (Digital Object Identifier) or URL (Uniform Resource Locator)

A DOI is a link to a resource on the internet. The resource can be a book or its chapter. On the other hand, a URL is an address that indicates where the resource can be found. It helps to locate the resource. The use of URLs and DOIs directs readers to the digital identifier of the source.

In-Text Citations

An in-text citation for a research paper is the brief form of the bibliography that you include in the body of the content. It contains the author’s family name and year of publication. It provides enough details to help users know the source in their reference list. Each citation format for research papers is unique.

See citation examples below.

How to Cite Direct Quotations for Each Citation Style

The general rule in referencing is that in-text citations must have a corresponding entry in your reference list. Let’s see how!

There are two types of APA in-text citations:

Parenthetical:

The researchers concluded, “Climate change poses significant challenges for coastal communities” (Johnson & Lee, 2021, p. 78).

In their study on the effects of exercise on mental health, Smith and Johnson (2019) found that regular physical activity was associated with a significant decrease in symptoms of anxiety and depression. According to their research, engaging in exercise three times a week for at least 30 minutes had a positive impact on participants’ overall well-being.

APA in-text citation style employs the source’s name and publication year. A direct quotation will include the page number. Remember, you can generate a citation in a research paper using the APA style via a citation generator.

MLA is known as the scientific style of citation. The uniqueness of MLA Style formatting is the use of a direct quote (in quotes), the Author’s name and page number (in parentheses).

In the novel “To Kill a Mockingbird,” Atticus Finch imparts wisdom to his children, saying, “You never really understand a person until you consider things from his point of view… until you climb into his skin and walk around in it” (Lee 30).

For Chicago, you are to include a parenthetical citation, the author’s name, the publication year, and the quote’s page number.

As Adams (2009) argues, “History is a vast early warning system” (53).

IEEE (Institute of Electrical and Electronics Engineers) style typically uses numerical citations in square brackets for in-text citations. It doesn’t rely heavily on direct quotations in the same way as some other citation styles, like APA or MLA. Instead, IEEE generally prefers paraphrasing and citing the source, but direct quotations can be used when necessary. Here’s an example of a direct quotation in IEEE style:

In-Text Citation:

As stated by Smith, “In most cases, the impedance of the transmission line remains relatively constant throughout its length” [1].

Corresponding Reference Entry:

[1] A. Smith, “Transmission Line Impedance Analysis,” IEEE Transactions on Electrical Engineering, vol. 45, no. 3, pp. 212-225, 2010.

ASA is different because it contains the author’s name, publication year, and even the page number.

According to Smith (2010), “Social institutions shape our behaviors and interactions in profound ways” (p. 45).

How to Cite Paraphrased Information

While writing a college paper, paraphrasing is important to achieve clarity, but it is ideal to cite the source of the paraphrased information. The proper way to cite paraphrased information is to include a parenthetical citation. The style of referencing for all citation styles doesn’t change, but they should be in parenthesis.

“Strength can be defined in terms of ability and acquired skills, according to (Jack et al. 2023).

Citing Multiple Authors

The technique is different when you are citing a source that has multiple authors. For the first-time citation, you should include the names of all the authors. The subsequent activities to generate a citation in APA should only include the first author’s surname and the proper use of ‘et al.’ However, you should include the surname and initials of all these authors in the full reference. Separate the authors with commas and ampersands before the final name.

Two Authors:

When a source has two authors, include both authors’ names in the in-text citation every time you reference the source. Use an ampersand (&) between the authors’ names, and include the year of publication in parentheses. For example:

(Smith & Johnson, 2020) found that…

Three to Five Authors:

When a source has three to five authors, list all authors in the first in-text citation. Use an ampersand (&) between the last two authors’ names. For subsequent citations of the same source, use only the first author’s name followed by “et al.” and the year. For example:

First citation: (Smith, Johnson, & Williams, 2018)…

Subsequent citations: (Smith et al., 2018)…

Six or More Authors:

When a source has six or more authors, you should use “et al.” in both the first and subsequent in-text citations, along with the year. For example:

(Smith et al., 2019) conducted a study on…

Group Authors:

When citing sources authored by a group, organization, or company, use the full name of the group or organization as the author in the in-text citation. If the abbreviation is well-known, you can use the abbreviation in subsequent citations. For example:

First citation: (American Psychological Association [APA], 2019)…

Subsequent citations: (APA, 2019)

When a source has two authors, include both authors’ names in the in-text citation, separated by the word “and.” For example:

(Smith and Johnson 45) found that…

Three or More Authors:

When a source has three or more authors, include only the first author’s name followed by “et al.” in the in-text citation. For example:

(Smith et al. 72) conducted a study on…

If a source has no identifiable author, use a shortened version of the title in the in-text citation. Enclose the title in double quotation marks or use italics if it’s a longer work (e.g., a book or film). For example:

(“Title of the Source” 28) argues that…

(American Psychological Association 62) states that…

Author-Date System:

In the Author-Date system, when a source has two authors, include both authors’ last names and the publication year in parentheses in the in-text citation, separated by an ampersand (&). For example:

(Smith & Johnson 2020) found that…

When a source has three or more authors, you can use “et al.” after the first author’s name in the in-text citation. For example:

(Smith et al. 2018) conducted a study on…

Notes and Bibliography System:

In the Notes and Bibliography system, when a source has two authors, include both authors’ full names in the note. For example:

John Smith and Jane Johnson, Title of the Work (Place of Publication: Publisher, Year), page number.

When a source has three or more authors, list the first author’s name followed by “et al.” in the note. For example:

John Smith et al., Title of the Work (Place of Publication: Publisher, Year), page number.

When a source has two authors, include both authors’ last names in the in-text citation, separated by the word “and.” For example:

(Smith and Johnson 2020) found that…

Three Authors:

When a source has three authors, include all three authors’ last names in the in-text citation, separated by commas. For example:

(Smith, Johnson, and Williams 2018) conducted a study on…

More than Three Authors:

When a source has more than three authors, you should use the first author’s last name followed by “et al.” in the in-text citation. For example:

(Smith et al. 2019) conducted a study on…

When a source has two authors, include both authors’ last names in the in-text citation, separated by “and.” For example:

[1] Smith and Johnson found that…

When a source has three or more authors, use the first author’s last name followed by “et al.” in the in-text citation. For example:

[2] Smith et al. conducted a study on…

Page Numbers in In-Text Citations

The use of page numbers in in-text citations is more peculiar to APA style. You can use paragraphs as indicated above if the source has no page, as seen in some e-books and websites.

Creating a Reference List or Bibliography

Creating a reference list is one of the most important tips for writing a research paper because it shows the general scheme of paper citation. This part of the content is a step-by-step process you can follow to create your reference list for your research paper.

Formatting and Organizing Your References

Formatting and organizing your references is the first step when you want to create your bibliography. You need to arrange all the full references to the in-text citation in the downward part of your paper. To avoid missing out on any, writing every full reference when you write the in-text citation is advisable.

Alphabetizing Your References

Alphabetizing your references ensures you create your bibliography in an orderly fashion for easy comprehension. Hence, you can do it numerically or alphabetically. The numerical order is dependent on the referencing system you are using, while the alphabetical order uses the author’s name to organize the reference.

Citations for Different Source Types

Different source types have their respective references, even for scientific papers. The commonest sources include books, journals, chapters, presentations, and online (to cite a website).

See how to cite an example for each source below:

Tips for Accuracy

The goal of citing your paper is because of the advantages stated above. As such, you should not negotiate the accuracy of your citation. Here are the tips you can follow for accurate referencing:

Verify Your Source

Confirm if your source is credible or not. It is easier to verify books, journal articles, and chapters. You should check multiple links to confirm their authenticity.

Follow the One Style Guide

Maintain a single referencing style throughout your paper. It is improper to employ multiple referencing styles. If not specified, you can consider the APA style.

Verify DOI and URLs

DOI and URLs can be tricky and sensitive. A simple error with the punctuation can make them invalid. Hence, verifying every DOI and URL with a click is advisable. Discrediting your citation format for a scientific research paper reference based on an invalid URL is not worth it.

Online Citation Generators

Thanks to the digital age, you don’t have to worry about manually compiling your reference or generating its in-text citation. You can employ online generators to do the rough work for you. In turn, you will have more time to focus on the major content of your research work.

Use University Libraries and Writing Centers

Libraries and writing centers have extensive collections of cited sources. Since books, publications, and journals are more credible sources, university libraries remain a valid source to increase the credibility of your paper.

Leave No Stone Unturned!

Referencing and citation are the best way to preserve the relevance of your academic paper. It gives it the appropriate credibility for future use. That means another writer can refer to your work over many years, even when the level of advancement may be unmatched. A well-referenced work is evergreen.

One must note that well-oriented research paper citations have a proper format. The options include APA, MLA (citation style for science), Chicago, IEEE, and ASA. If not stated, it is advisable to follow the APA formatting style, as it is the most common. However, stick with formatting while compiling cited sources for a research paper.

A Quick Guide to Harvard Referencing | Citation Examples

Published on 14 February 2020 by Jack Caulfield . Revised on 15 September 2023.

Referencing is an important part of academic writing. It tells your readers what sources you’ve used and how to find them.

Harvard is the most common referencing style used in UK universities. In Harvard style, the author and year are cited in-text, and full details of the source are given in a reference list .

Table of contents

Harvard in-text citation, creating a harvard reference list, harvard referencing examples, referencing sources with no author or date, frequently asked questions about harvard referencing.

A Harvard in-text citation appears in brackets beside any quotation or paraphrase of a source. It gives the last name of the author(s) and the year of publication, as well as a page number or range locating the passage referenced, if applicable:

Note that ‘p.’ is used for a single page, ‘pp.’ for multiple pages (e.g. ‘pp. 1–5’).

An in-text citation usually appears immediately after the quotation or paraphrase in question. It may also appear at the end of the relevant sentence, as long as it’s clear what it refers to.

When your sentence already mentions the name of the author, it should not be repeated in the citation:

Sources with multiple authors

When you cite a source with up to three authors, cite all authors’ names. For four or more authors, list only the first name, followed by ‘ et al. ’:

Sources with no page numbers

Some sources, such as websites , often don’t have page numbers. If the source is a short text, you can simply leave out the page number. With longer sources, you can use an alternate locator such as a subheading or paragraph number if you need to specify where to find the quote:

Multiple citations at the same point

When you need multiple citations to appear at the same point in your text – for example, when you refer to several sources with one phrase – you can present them in the same set of brackets, separated by semicolons. List them in order of publication date:

Multiple sources with the same author and date

If you cite multiple sources by the same author which were published in the same year, it’s important to distinguish between them in your citations. To do this, insert an ‘a’ after the year in the first one you reference, a ‘b’ in the second, and so on:

Prevent plagiarism, run a free check.

A bibliography or reference list appears at the end of your text. It lists all your sources in alphabetical order by the author’s last name, giving complete information so that the reader can look them up if necessary.

The reference entry starts with the author’s last name followed by initial(s). Only the first word of the title is capitalised (as well as any proper nouns).

Sources with multiple authors in the reference list

As with in-text citations, up to three authors should be listed; when there are four or more, list only the first author followed by ‘ et al. ’:

Reference list entries vary according to source type, since different information is relevant for different sources. Formats and examples for the most commonly used source types are given below.

• Entire book
• Book chapter
• Translated book
• Edition of a book

Journal articles

• Print journal
• Online-only journal with DOI
• Online-only journal with no DOI
• General web page
• Online article or blog
• Social media post

Sometimes you won’t have all the information you need for a reference. This section covers what to do when a source lacks a publication date or named author.

No publication date

When a source doesn’t have a clear publication date – for example, a constantly updated reference source like Wikipedia or an obscure historical document which can’t be accurately dated – you can replace it with the words ‘no date’:

Note that when you do this with an online source, you should still include an access date, as in the example.

When a source lacks a clearly identified author, there’s often an appropriate corporate source – the organisation responsible for the source – whom you can credit as author instead, as in the Google and Wikipedia examples above.

When that’s not the case, you can just replace it with the title of the source in both the in-text citation and the reference list:

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.

A Harvard in-text citation should appear in brackets every time you quote, paraphrase, or refer to information from a source.

The citation can appear immediately after the quotation or paraphrase, or at the end of the sentence. If you’re quoting, place the citation outside of the quotation marks but before any other punctuation like a comma or full stop.

In Harvard referencing, up to three author names are included in an in-text citation or reference list entry. When there are four or more authors, include only the first, followed by ‘ et al. ’

Though the terms are sometimes used interchangeably, there is a difference in meaning:

• A reference list only includes sources cited in the text – every entry corresponds to an in-text citation .
• A bibliography also includes other sources which were consulted during the research but not cited.

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)

Table of Contents

Every scientific paper builds on previous research – even if it’s in a new field, related studies will have preceded and informed it. In peer-reviewed articles, authors must give credit to this previous research, through citations and references. Not only does this show clearly where the current research came from, but it also helps readers understand the content of the paper better.

There is no optimum number of references for an academic article but depending on the subject you could be dealing with more than 100 different papers, conference reports, video articles, medical guidelines or any number of other resources.

That’s a lot of content to manage. Before submitting your manuscript, this needs to be checked, cross-references in the text and the list, organized and formatted.

The exact content and format of the citations and references in your paper will depend on the journal you aim to publish in, so the first step is to check the journal’s Guide for Authors before you submit.

There are two main points to pay attention to – consistency and accuracy. When you go through your manuscript to edit or proofread it, look closely at the citations within the text. Are they all the same? For example, if the journal prefers the citations to be in the format (name, year), make sure they’re all the same: (Smith, 2016).

Your citations must also be accurate and complete. Do they match your references list? Each citation should be included in the list, so cross-checking is important. It’s also common for journals to prefer that most, if not all, of the articles listed in your references be cited within the text – after all, these should be studies that contributed to the knowledge underpinning your work, not just your bedtime reading. So go through them carefully, noting any missing references or citations and filling the gaps.

Each journal has its own requirements when it comes to the content and format of references, as well as where and how you should include them in your submission, so double-check before you hit send!

In general, a reference will include authors’ names and initials, the title of the article, name of the journal, volume and issue, date, page numbers and DOI. On ScienceDirect, articles are linked to their original source (if also published on ScienceDirect) or to their Scopus record, so including the DOI can help link to the correct article.

A spotless reference list

Luckily, compiling and editing the references in your scientific manuscript can be easy – and it no longer has to be manual. Management tools like Mendeley can keep track of all your references, letting you share them with your collaborators. With the Word plugin, it’s possible to select the right citation style for the journal you’re submitting to and the tool will format your references automatically.

Like with any other part of your manuscript, it’s important to make sure your reference list has been checked and edited. Elsevier Author Services Language Editing can help, with professional manuscript editing that will help make sure your references don’t hold you back from publication.

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?"

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

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.

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.

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

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.

Magazine Article

Clay, R. (2008, June). Science vs. ideology: Psychologists fight back about the misuse of research. Monitor on Psychology , 39 (6). https://www.apa.org/monitor/2008/06/ideology

Note that for citations, include only the year: Clay (2008). For magazine articles retrieved from a common academic research database, leave out the URL. For magazine articles from an online news website that is not an online version of a print magazine, follow the format for a webpage reference list entry.

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

Walden University Academic Skills Center. (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.

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.

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 "

How To Write References for Academic & Scientific Research Papers

How To Write References for Academic and Scientific Research Papers Writing accurate & appropriate references is an essential aspect of preparing a research paper for successful publication, examination or any other kind of serious dissemination or evaluation. This article explains exactly how to write perfect references in two widely used scholarly styles: the parenthetical author–date system recommended by the American Psychological Association (APA) & the sequential numerical or Vancouver system frequently used in the sciences. The post also includes several clear examples of in-text citations & complete bibliographical references formatted in both styles. Neither of these documentation styles is inherently complex, though each does have its characteristic pitfalls, and the utmost accuracy is essential when using either. Accusations of plagiarism or misrepresentation of the work of other scholars can be the unpleasant result if authors are not absolutely correct and scrupulously thorough in providing citations and references when they should to acknowledge the research of others. In addition, publication attempts can prove unsuccessful and grades lower than expected if instructions and guidelines for references are not observed with precision and consistency. The discussion and examples offered below outline exactly how to provide scholarly references for articles and books in one version of an author–date documentation style – APA – and one of a numerical style – Vancouver – but do be aware that various versions of these two basic styles exist, so consulting the guidelines, instructions or manual specific to the research paper you are writing is always imperative before finalising formats for in-text citations and complete references. PhD Thesis Editing Services Writing APA Author–Date References for a Research Paper Writing an accurate and appropriate APA author–date reference is a two-stage process involving 1) the creation of an in-text citation in the main body of the paper and 2) the addition of a complete bibliographical entry about the source in a list of references at the end of the paper.

1. The in-text citation should contain the last name of the author (or last names of the authors if there is more than one) who wrote the article, book or other document followed by the document’s date of publication. This information most frequently appears in parentheses immediately after the statement related to the paper, as in this example: • A recent study of the text presents a similar argument (Wilson & Bond, 2016). Alternatively, the names of the authors or the date of publication can be integrated into the main text, with the remaining information presented in parentheses: • Wilson and Bond present a similar argument in their recent study of the text (2016). • A 2016 examination of the text presents a similar argument (Wilson & Bond). Rewording of the main text is obviously necessary, but the only difference (beyond arrangement) in the citation information itself is that the word ‘and’ is used between the author names in the main text, whereas an ampersand (&) is used between those names when they appear in parentheses. The parentheses can sometimes be eliminated altogether by writing both author names and publication date in the main text: • Wilson and Bond’s 2016 study of the text presents a similar argument. Page numbers can be used for referring to specific information in particular parts of a publication, but they are usually only required in APA style for direct quotations when a passage or other part of a published document is reproduced word for word in a new research paper. In such cases, the page number is separated from the publication date by a comma and preceded by the abbreviation ‘p.’ for ‘page’: • As Wilson and Bond explain, ‘the political reading of the text, even the most personal of its episodes, seems universal until the book falls into a woman’s hands’ (2016, p.88).

When two or more sources are cited in the same set of parentheses, semicolons are used to separate the sources: • Both studies consider the poem in relation to urban culture (Samuel & Watson, 2013; Wilson & Bond, 2016). The normal arrangement when multiple sources are cited in a single set of parentheses is to observe alphabetical order according to the author names, as I have done above (with ‘Samuel’ preceding ‘Wilson’). Notice that the in-text citation takes the same form whether the source cited is a book or an article, with ‘Samuel & Watson’ referring here to a monograph and ‘Wilson & Bond’ to a journal article. PhD Thesis Editing Services 2. Every source cited in the text of an academic or scientific research paper using APA style should also be included in a list that is entitled ‘References’ and presented at the end of the paper. An APA list of references should be arranged alphabetically based on author names, and all the bibliographical information required for readers to find each source must be provided in a specific format. The author names for a publication come first and are inverted, with the last name of the first author of each document opening the bibliographical entry. Author names are followed by the date of publication (in parentheses), with these two pieces of information serving readers by connecting the complete reference to the in-text citation. It is therefore vital that the last names of authors and the publication dates provided in both places are checked against each other for errors and inconsistencies and then carefully corrected to agree with precision.

For the complete reference to a journal article, the title of the article follows the date of publication. The name and volume number of the journal come next, both of them in italic font, though do be aware that special fonts may not be displayed in this post. The pages on which the article can be found come next, and if there is a doi or url for an online version of the paper, that should be the last item in the entry, which would take this form: • Wilson, S., & Bond, F. (2016). Political and personal readings of the earliest zone poem. Urban Poetry, 12, 72–94. doi:00.0000/00000000000000 For the complete reference to a book, the information, and thus the format, is a little different. The title of the book follows the publication date and appears in italic font, with the place of publication and publisher’s name completing the reference: • Samuel, H., & Watson, M. (2013). Political poetry and modern urbanity. London: Big City Press.

Writing Sequential Numerical References for a Research Paper The same two-step process is necessary when writing the sequential numerical references used for Vancouver style documentation, but in-text citations are notably simpler, a different arrangement is used for the list of references and a somewhat different format is required for the complete bibliographical entries included in the list.

1. For a numerical in-text citation, a single Arabic numeral is all that is required. Each source is assigned a number when it is first cited, so the sources used in a research paper are numbered sequentially according to the order of first citation, with each source retaining throughout the paper the number it was originally assigned. The first source cited would therefore be reference 1, the second reference 2 and so on. The International Committee of Medical Journal Editors (ICMJE) recommends placing these reference numbers in parentheses, with a citation taking this form: • A recent study of the text presents a similar argument (1). As is the case with author–date citations, information about sources can also be added in the main text: • Wilson and Bond present a similar argument in their recent study of the text (1). • A 2016 examination of the text presents a similar argument (1). • Wilson and Bond’s 2016 study of the text presents a similar argument (1). Unlike author–date citations, however, this additional information in the text does not negate the need for the reference number, which is always required.

If you need to cite a specific page of a document to point readers to a particular piece of information or indicate the location of a quoted passage, the page number should be added after the reference number, usually with a comma to separate it from the reference number and a preceding ‘p.’ to avoid confusion: • As Wilson and Bond explain, ‘the political reading of the text, even the most personal of its episodes, seems universal until the book falls into a woman’s hands’ (1, p.88). When two or more sources are cited at the same time, commas are generally used to separate the reference numbers, usually without intervening spaces: • Several studies have taken this approach to the text (1,2,5–8). PhD Thesis Editing Services 2. The reference list for sequential numerical citations is arranged, not surprisingly, by the numerical sequence of the citations. This means that the first source cited in a research paper (reference 1) is also the first source listed in the References section of the paper, the second is the second source in the list and so on. The following two sample references follow ICMJE guidelines and would serve as the opening entries in a numerical list of references: • 1. Wilson S, Bond F. Political and personal readings of the earliest zone poem. Urban Poetry. 2016;12:72–94. doi:00.0000/00000000000000. • 2. Samuel H, Watson M. Political Poetry and Modern Urbanity. London: Big City Press; 2013.

As these examples show, the information required for a complete reference varies according to the nature of the source cited, just as it does with author–date references. In addition, the names of journals (but not books) are often abbreviated when preparing numerical references. It is essential, however, that the correct or standard abbreviation for each journal be used when shortening journal titles, which can easily be confused in their abbreviated forms, so a little research may be necessary to determine the right abbreviation. Use of the complete journal title is recommended when there is any doubt or there is no standard abbreviation. A cautionary note is in order when writing sequential numerical references. Adding or deleting sources from a numerical list of references that has been arranged according to the order in which sources are first cited can necessitate changes in subsequent list entries as well as in the in-text citations, and the same is the case with any changes to those in-text citations. The reason is simple: if, for example, you remove reference 3 from the text or list, what was reference 4 becomes reference 3, what was reference 5 becomes reference 4 and so on. If you add that removed reference back in elsewhere more alterations will ensue. It is therefore wise to check and finalise the order of the reference list very carefully indeed after all the in-text citations are in their final places, and to ensure that the assigned reference numbers agree with the utmost accuracy between in-text citations and the list of references.

While references are an essential and integral part of a scientific manuscript, format and style of references are as varied as the number of journals currently present. International Committee of Medical Journal Editors in their latest recommendations for publication, 1 advice authors to quote original references whenever possible. We would recommend the readers to go through these guidelines as they are given in sufficient detail to submit a good set of references including styling. Other resources for citing references include the PubMed section 2 which gives samples of formatting of different reference types and the eBook: Citing Medicine, 3 published by the U. S. National Library of Medicine, which gives assistance and rules to authors, editors, publishers and librarians for formatting of references for different reference types.

References are formatted in two basic styles – the Vancouver style which is numeric (more commonly used in medical journals) and Harvard which uses author-date style (more commonly used in natural and Social sciences journals). 4 Parts and order of the parts cited differ on what the author is citing (reference type) and the journal that is being submitted to. The most common types of references include journal article, book, book section or chapter, dissertation, monograph, and webpage. As an example, for a journal article, the parts of a reference in the sequence include authors, article title, journal title, date of publication, volume, issue, and location/pagination. Each journal has its own modification of the format for each part and the punctuation marks, or their lack of, between the parts. Formatting style in each part of a reference could involve placement of selected punctuation marks, bold and italics enhancements, alphabetical order or sequential ordering of references and style of citing in the text, making the combination of variations that create a unique reference style as large in number as the number of journals currently published. It is not clear why such a system has evolved, but it requires considerable attention to detail to get the formatting correct and is time-consuming for the author. The tradition of the journal has been thought as one of the reasons. 4 In manuscripts submitted for the Indian Journal of Orthopaedics (IJO), the reference section carries the most formatting errors committed by authors.

The advantage of having a constant style within a journal is two-fold, apart from an esthetic appearance of references across all articles published by the journal. Ease of reading the references at the end of each article and ease of finding reference part by the reader if he/she is used to the format and plans to look up the reference. As a student/professional in the medical field, one would require attention to finer details of his/her research work as well as in their clinical practice and hence exercising attention to the references would help improve those skills. Such a wide variation in the styles of references has also benefitted some software companies who deal with reference managers (RMs). Some RMs are free for use, and the authors are advised to use different RMs to see which one suits their needs best. While some RMs are cloud based, others are computer based and do not require an internet connection while some others are cloud and computer based. The variation in the style of references across journals appears unlikely to be standardized to a single universal format in the near future.

The Citation Style Language (CSL) is an XML-based computer language developed to standardize formatting of citations and references in manuscripts submitting to journals. They are text application editable files which are imported into RMs. An increasing number of RMs use CSL to help users format their list of references according to individual journal guidelines. However, not all journals are supported by CSL files.

There are two main repositories for access to CSL files – One by GitHub 5 and the other by Zotero 6 developed by Corporation for Digital Scholarship and Roy Rosenzweig Center for History and New Media. These contain more than 8500 styles of references. Authors using Zotero, Mendeley, RefWorks, Papers, CrossRef, Bibliography, and some 42 other RMs can use these CSL files to manage references within them. IJO did not have a CSL file until now in both the repositories. In this scenario, there are a few options for the authors preparing references for a manuscript. First, to type and style references manually which would take a long time and prone to human errors. Second, a CSL file similar to IJO may be selected from the repository and used and later manually edited, if any needed. However, this involves searching for an exact match of style for a journal registered in the repository of CSL files. Third, there are RMs with inbuilt options to format references while citing in the text. This option is independent of CSL. The disadvantage here is that the author is bound by the list of reference styles already loaded within the software. They may not be able to add new formats. Fourth, some RMs allow authors to prepare a style, but this would take some time to prepare if the style is not already inbuilt. As a fifth option, a CSL file that is close to IJO may be chosen, and the code of this file tweaked with minor editing to convert it for use with IJO. To do that, the author must be familiar with programming or editing of HTML/XML files since HTML is a language that is closer to XML.

Zotero's repository 7 website has a user-friendly interface in which such searches are easier to perform. It has 9357 styles stored in the repository at the time of writing this article on March 17, 2019. There are 1924 unique styles through which one can search if their required journal is listed. Zotero draws CSL files from GitHub into their repository. Hence, if a file is created in GitHub, it is drawn into Zotero by default. CSL Project 8 is a website sponsored by four well known RMs. These are Zotero, Mendeley, 9 Papers, 10 and RefWorks. 11 This website gives detailed specifications and documentation of CSL language if one is interested in coding these files. If one is proficient with XML, they can create a style and submit it to the GitHub website for others to benefit. Editing is easier if one uses the Zotero RM as it has an inbuilt option to edit style. It can be done even in other managers or with the use of a standard text editing application in Windows or Mac operating systems. Once a new CSL file is developed, in order to publish it, it has to be validated by CSL validator website 12 and submitted at the GitHub site for accepting into the repository. Even finer details like number of author names before et al. while formatting reference, punctuation marks and their placement, style of each part of the reference and each style of the reference, etc., can be edited accurately.

Once developed, the output of references and citations is remarkably consistent, and too much time need not be directed to editing the punctuation marks and styling of the references and citations while preparing the manuscript. The only hurdle after this would be to get full details of the references reliably and accurately into the RM database while importing the references. The author needs to check that the references were properly imported into the database. If verified, they may be used any number of times with precision. With appropriate selection, the citing as well as the list of references can be formatted according to the journal that is being considered, for submission. Those who are already using RMs may be well aware of the advantages and the time such CSL files can save while preparing a manuscript.

We are happy to inform that a CSL file for IJO has now been created in the GitHub repository 1 and Zotero Styles repository 3 and it can be used by authors using the RMs listed in the CSL website and benefit from its use. The direct link of the file in the repository is given 13 [ Figure 1 ]. Basic users of RMs may download it through their RMs by selecting Indian Journal of Orthopaedics option. Advanced users who know where to place this file may access using the weblink given. Examples of reference style and citation for IJO are given in Figure 2 .

Research Paper

Definition:

Research Paper is a written document that presents the author’s original research, analysis, and interpretation of a specific topic or issue.

It is typically based on Empirical Evidence, and may involve qualitative or quantitative research methods, or a combination of both. The purpose of a research paper is to contribute new knowledge or insights to a particular field of study, and to demonstrate the author’s understanding of the existing literature and theories related to the topic.

Structure of Research Paper

The structure of a research paper typically follows a standard format, consisting of several sections that convey specific information about the research study. The following is a detailed explanation of the structure of a research paper:

The title page contains the title of the paper, the name(s) of the author(s), and the affiliation(s) of the author(s). It also includes the date of submission and possibly, the name of the journal or conference where the paper is to be published.

The abstract is a brief summary of the research paper, typically ranging from 100 to 250 words. It should include the research question, the methods used, the key findings, and the implications of the results. The abstract should be written in a concise and clear manner to allow readers to quickly grasp the essence of the research.

Introduction

The introduction section of a research paper provides background information about the research problem, the research question, and the research objectives. It also outlines the significance of the research, the research gap that it aims to fill, and the approach taken to address the research question. Finally, the introduction section ends with a clear statement of the research hypothesis or research question.

Literature Review

The literature review section of a research paper provides an overview of the existing literature on the topic of study. It includes a critical analysis and synthesis of the literature, highlighting the key concepts, themes, and debates. The literature review should also demonstrate the research gap and how the current study seeks to address it.

The methods section of a research paper describes the research design, the sample selection, the data collection and analysis procedures, and the statistical methods used to analyze the data. This section should provide sufficient detail for other researchers to replicate the study.

The results section presents the findings of the research, using tables, graphs, and figures to illustrate the data. The findings should be presented in a clear and concise manner, with reference to the research question and hypothesis.

The discussion section of a research paper interprets the findings and discusses their implications for the research question, the literature review, and the field of study. It should also address the limitations of the study and suggest future research directions.

The conclusion section summarizes the main findings of the study, restates the research question and hypothesis, and provides a final reflection on the significance of the research.

The references section provides a list of all the sources cited in the paper, following a specific citation style such as APA, MLA or Chicago.

Title: The Impact of Social Media on Mental Health among Young Adults

Abstract: This study aims to investigate the impact of social media use on the mental health of young adults. A literature review was conducted to examine the existing research on the topic. A survey was then administered to 200 university students to collect data on their social media use, mental health status, and perceived impact of social media on their mental health. The results showed that social media use is positively associated with depression, anxiety, and stress. The study also found that social comparison, cyberbullying, and FOMO (Fear of Missing Out) are significant predictors of mental health problems among young adults.

Introduction: Social media has become an integral part of modern life, particularly among young adults. While social media has many benefits, including increased communication and social connectivity, it has also been associated with negative outcomes, such as addiction, cyberbullying, and mental health problems. This study aims to investigate the impact of social media use on the mental health of young adults.

Literature Review: The literature review highlights the existing research on the impact of social media use on mental health. The review shows that social media use is associated with depression, anxiety, stress, and other mental health problems. The review also identifies the factors that contribute to the negative impact of social media, including social comparison, cyberbullying, and FOMO.

Methods : A survey was administered to 200 university students to collect data on their social media use, mental health status, and perceived impact of social media on their mental health. The survey included questions on social media use, mental health status (measured using the DASS-21), and perceived impact of social media on their mental health. Data were analyzed using descriptive statistics and regression analysis.

Results : The results showed that social media use is positively associated with depression, anxiety, and stress. The study also found that social comparison, cyberbullying, and FOMO are significant predictors of mental health problems among young adults.

Discussion : The study’s findings suggest that social media use has a negative impact on the mental health of young adults. The study highlights the need for interventions that address the factors contributing to the negative impact of social media, such as social comparison, cyberbullying, and FOMO.

Conclusion : In conclusion, social media use has a significant impact on the mental health of young adults. The study’s findings underscore the need for interventions that promote healthy social media use and address the negative outcomes associated with social media use. Future research can explore the effectiveness of interventions aimed at reducing the negative impact of social media on mental health. Additionally, longitudinal studies can investigate the long-term effects of social media use on mental health.

Limitations : The study has some limitations, including the use of self-report measures and a cross-sectional design. The use of self-report measures may result in biased responses, and a cross-sectional design limits the ability to establish causality.

Implications: The study’s findings have implications for mental health professionals, educators, and policymakers. Mental health professionals can use the findings to develop interventions that address the negative impact of social media use on mental health. Educators can incorporate social media literacy into their curriculum to promote healthy social media use among young adults. Policymakers can use the findings to develop policies that protect young adults from the negative outcomes associated with social media use.

They also demonstrate the author’s ability to critically evaluate existing literature, synthesize information from multiple sources, and write in a clear and structured manner.

Characteristics of Research Paper

Research papers have several characteristics that distinguish them from other forms of academic or professional writing. Here are some common characteristics of research papers:

• Evidence-based: Research papers are based on empirical evidence, which is collected through rigorous research methods such as experiments, surveys, observations, or interviews. They rely on objective data and facts to support their claims and conclusions.
• Structured and organized: Research papers have a clear and logical structure, with sections such as introduction, literature review, methods, results, discussion, and conclusion. They are organized in a way that helps the reader to follow the argument and understand the findings.
• Formal and objective: Research papers are written in a formal and objective tone, with an emphasis on clarity, precision, and accuracy. They avoid subjective language or personal opinions and instead rely on objective data and analysis to support their arguments.
• Citations and references: Research papers include citations and references to acknowledge the sources of information and ideas used in the paper. They use a specific citation style, such as APA, MLA, or Chicago, to ensure consistency and accuracy.
• Peer-reviewed: Research papers are often peer-reviewed, which means they are evaluated by other experts in the field before they are published. Peer-review ensures that the research is of high quality, meets ethical standards, and contributes to the advancement of knowledge in the field.
• Objective and unbiased: Research papers strive to be objective and unbiased in their presentation of the findings. They avoid personal biases or preconceptions and instead rely on the data and analysis to draw conclusions.

Advantages of Research Paper

Research papers have many advantages, both for the individual researcher and for the broader academic and professional community. Here are some advantages of research papers:

• Contribution to knowledge: Research papers contribute to the body of knowledge in a particular field or discipline. They add new information, insights, and perspectives to existing literature and help advance the understanding of a particular phenomenon or issue.
• Opportunity for intellectual growth: Research papers provide an opportunity for intellectual growth for the researcher. They require critical thinking, problem-solving, and creativity, which can help develop the researcher’s skills and knowledge.
• Career advancement: Research papers can help advance the researcher’s career by demonstrating their expertise and contributions to the field. They can also lead to new research opportunities, collaborations, and funding.

13.1 Formatting a Research Paper

Learning objectives.

• Identify the major components of a research paper written using American Psychological Association (APA) style.
• Apply general APA style and formatting conventions in a research paper.

In this chapter, you will learn how to use APA style , the documentation and formatting style followed by the American Psychological Association, as well as MLA style , from the Modern Language Association. There are a few major formatting styles used in academic texts, including AMA, Chicago, and Turabian:

• AMA (American Medical Association) for medicine, health, and biological sciences
• APA (American Psychological Association) for education, psychology, and the social sciences
• Chicago—a common style used in everyday publications like magazines, newspapers, and books
• MLA (Modern Language Association) for English, literature, arts, and humanities
• Turabian—another common style designed for its universal application across all subjects and disciplines

While all the formatting and citation styles have their own use and applications, in this chapter we focus our attention on the two styles you are most likely to use in your academic studies: APA and MLA.

If you find that the rules of proper source documentation are difficult to keep straight, you are not alone. Writing a good research paper is, in and of itself, a major intellectual challenge. Having to follow detailed citation and formatting guidelines as well may seem like just one more task to add to an already-too-long list of requirements.

Following these guidelines, however, serves several important purposes. First, it signals to your readers that your paper should be taken seriously as a student’s contribution to a given academic or professional field; it is the literary equivalent of wearing a tailored suit to a job interview. Second, it shows that you respect other people’s work enough to give them proper credit for it. Finally, it helps your reader find additional materials if he or she wishes to learn more about your topic.

Furthermore, producing a letter-perfect APA-style paper need not be burdensome. Yes, it requires careful attention to detail. However, you can simplify the process if you keep these broad guidelines in mind:

• Work ahead whenever you can. Chapter 11 “Writing from Research: What Will I Learn?” includes tips for keeping track of your sources early in the research process, which will save time later on.
• Get it right the first time. Apply APA guidelines as you write, so you will not have much to correct during the editing stage. Again, putting in a little extra time early on can save time later.
• Use the resources available to you. In addition to the guidelines provided in this chapter, you may wish to consult the APA website at http://www.apa.org or the Purdue University Online Writing lab at http://owl.english.purdue.edu , which regularly updates its online style guidelines.

General Formatting Guidelines

This chapter provides detailed guidelines for using the citation and formatting conventions developed by the American Psychological Association, or APA. Writers in disciplines as diverse as astrophysics, biology, psychology, and education follow APA style. The major components of a paper written in APA style are listed in the following box.

These are the major components of an APA-style paper:

Body, which includes the following:

• Headings and, if necessary, subheadings to organize the content
• In-text citations of research sources
• References page

All these components must be saved in one document, not as separate documents.

The title page of your paper includes the following information:

• Title of the paper
• Author’s name
• Name of the institution with which the author is affiliated
• Header at the top of the page with the paper title (in capital letters) and the page number (If the title is lengthy, you may use a shortened form of it in the header.)

List the first three elements in the order given in the previous list, centered about one third of the way down from the top of the page. Use the headers and footers tool of your word-processing program to add the header, with the title text at the left and the page number in the upper-right corner. Your title page should look like the following example.

The next page of your paper provides an abstract , or brief summary of your findings. An abstract does not need to be provided in every paper, but an abstract should be used in papers that include a hypothesis. A good abstract is concise—about one hundred fifty to two hundred fifty words—and is written in an objective, impersonal style. Your writing voice will not be as apparent here as in the body of your paper. When writing the abstract, take a just-the-facts approach, and summarize your research question and your findings in a few sentences.

In Chapter 12 “Writing a Research Paper” , you read a paper written by a student named Jorge, who researched the effectiveness of low-carbohydrate diets. Read Jorge’s abstract. Note how it sums up the major ideas in his paper without going into excessive detail.

Write an abstract summarizing your paper. Briefly introduce the topic, state your findings, and sum up what conclusions you can draw from your research. Use the word count feature of your word-processing program to make sure your abstract does not exceed one hundred fifty words.

Depending on your field of study, you may sometimes write research papers that present extensive primary research, such as your own experiment or survey. In your abstract, summarize your research question and your findings, and briefly indicate how your study relates to prior research in the field.

Margins, Pagination, and Headings

APA style requirements also address specific formatting concerns, such as margins, pagination, and heading styles, within the body of the paper. Review the following APA guidelines.

Use these general guidelines to format the paper:

• Set the top, bottom, and side margins of your paper at 1 inch.
• Use double-spaced text throughout your paper.
• Use a standard font, such as Times New Roman or Arial, in a legible size (10- to 12-point).
• Use continuous pagination throughout the paper, including the title page and the references section. Page numbers appear flush right within your header.
• Section headings and subsection headings within the body of your paper use different types of formatting depending on the level of information you are presenting. Additional details from Jorge’s paper are provided.

Begin formatting the final draft of your paper according to APA guidelines. You may work with an existing document or set up a new document if you choose. Include the following:

• Your title page
• The abstract you created in Note 13.8 “Exercise 1”
• Correct headers and page numbers for your title page and abstract

APA style uses section headings to organize information, making it easy for the reader to follow the writer’s train of thought and to know immediately what major topics are covered. Depending on the length and complexity of the paper, its major sections may also be divided into subsections, sub-subsections, and so on. These smaller sections, in turn, use different heading styles to indicate different levels of information. In essence, you are using headings to create a hierarchy of information.

The following heading styles used in APA formatting are listed in order of greatest to least importance:

• Section headings use centered, boldface type. Headings use title case, with important words in the heading capitalized.
• Subsection headings use left-aligned, boldface type. Headings use title case.
• The third level uses left-aligned, indented, boldface type. Headings use a capital letter only for the first word, and they end in a period.
• The fourth level follows the same style used for the previous level, but the headings are boldfaced and italicized.
• The fifth level follows the same style used for the previous level, but the headings are italicized and not boldfaced.

Visually, the hierarchy of information is organized as indicated in Table 13.1 “Section Headings” .

Table 13.1 Section Headings

A college research paper may not use all the heading levels shown in Table 13.1 “Section Headings” , but you are likely to encounter them in academic journal articles that use APA style. For a brief paper, you may find that level 1 headings suffice. Longer or more complex papers may need level 2 headings or other lower-level headings to organize information clearly. Use your outline to craft your major section headings and determine whether any subtopics are substantial enough to require additional levels of headings.

Working with the document you developed in Note 13.11 “Exercise 2” , begin setting up the heading structure of the final draft of your research paper according to APA guidelines. Include your title and at least two to three major section headings, and follow the formatting guidelines provided above. If your major sections should be broken into subsections, add those headings as well. Use your outline to help you.

Because Jorge used only level 1 headings, his Exercise 3 would look like the following:

Citation Guidelines

In-text citations.

Throughout the body of your paper, include a citation whenever you quote or paraphrase material from your research sources. As you learned in Chapter 11 “Writing from Research: What Will I Learn?” , the purpose of citations is twofold: to give credit to others for their ideas and to allow your reader to follow up and learn more about the topic if desired. Your in-text citations provide basic information about your source; each source you cite will have a longer entry in the references section that provides more detailed information.

In-text citations must provide the name of the author or authors and the year the source was published. (When a given source does not list an individual author, you may provide the source title or the name of the organization that published the material instead.) When directly quoting a source, it is also required that you include the page number where the quote appears in your citation.

This information may be included within the sentence or in a parenthetical reference at the end of the sentence, as in these examples.

Epstein (2010) points out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Here, the writer names the source author when introducing the quote and provides the publication date in parentheses after the author’s name. The page number appears in parentheses after the closing quotation marks and before the period that ends the sentence.

Addiction researchers caution that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (Epstein, 2010, p. 137).

Here, the writer provides a parenthetical citation at the end of the sentence that includes the author’s name, the year of publication, and the page number separated by commas. Again, the parenthetical citation is placed after the closing quotation marks and before the period at the end of the sentence.

As noted in the book Junk Food, Junk Science (Epstein, 2010, p. 137), “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive.”

Here, the writer chose to mention the source title in the sentence (an optional piece of information to include) and followed the title with a parenthetical citation. Note that the parenthetical citation is placed before the comma that signals the end of the introductory phrase.

David Epstein’s book Junk Food, Junk Science (2010) pointed out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Another variation is to introduce the author and the source title in your sentence and include the publication date and page number in parentheses within the sentence or at the end of the sentence. As long as you have included the essential information, you can choose the option that works best for that particular sentence and source.

Citing a book with a single author is usually a straightforward task. Of course, your research may require that you cite many other types of sources, such as books or articles with more than one author or sources with no individual author listed. You may also need to cite sources available in both print and online and nonprint sources, such as websites and personal interviews. Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.2 “Citing and Referencing Techniques” and Section 13.3 “Creating a References Section” provide extensive guidelines for citing a variety of source types.

Writing at Work

APA is just one of several different styles with its own guidelines for documentation, formatting, and language usage. Depending on your field of interest, you may be exposed to additional styles, such as the following:

• MLA style. Determined by the Modern Languages Association and used for papers in literature, languages, and other disciplines in the humanities.
• Chicago style. Outlined in the Chicago Manual of Style and sometimes used for papers in the humanities and the sciences; many professional organizations use this style for publications as well.
• Associated Press (AP) style. Used by professional journalists.

References List

The brief citations included in the body of your paper correspond to the more detailed citations provided at the end of the paper in the references section. In-text citations provide basic information—the author’s name, the publication date, and the page number if necessary—while the references section provides more extensive bibliographical information. Again, this information allows your reader to follow up on the sources you cited and do additional reading about the topic if desired.

The specific format of entries in the list of references varies slightly for different source types, but the entries generally include the following information:

• The name(s) of the author(s) or institution that wrote the source
• The year of publication and, where applicable, the exact date of publication
• The full title of the source
• For books, the city of publication
• For articles or essays, the name of the periodical or book in which the article or essay appears
• For magazine and journal articles, the volume number, issue number, and pages where the article appears
• For sources on the web, the URL where the source is located

The references page is double spaced and lists entries in alphabetical order by the author’s last name. If an entry continues for more than one line, the second line and each subsequent line are indented five spaces. Review the following example. ( Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.3 “Creating a References Section” provides extensive guidelines for formatting reference entries for different types of sources.)

In APA style, book and article titles are formatted in sentence case, not title case. Sentence case means that only the first word is capitalized, along with any proper nouns.

Key Takeaways

• Following proper citation and formatting guidelines helps writers ensure that their work will be taken seriously, give proper credit to other authors for their work, and provide valuable information to readers.
• Working ahead and taking care to cite sources correctly the first time are ways writers can save time during the editing stage of writing a research paper.
• APA papers usually include an abstract that concisely summarizes the paper.
• APA papers use a specific headings structure to provide a clear hierarchy of information.
• In APA papers, in-text citations usually include the name(s) of the author(s) and the year of publication.
• In-text citations correspond to entries in the references section, which provide detailed bibliographical information about a source.

How To Write a Reference Letter (Examples and Free Template)

Pass along your praise in a meaningful way.

Teacher job searches frequently require something many other careers don’t: a letter of reference. Both principals and teachers may find themselves asked to write these letters for their employees or coworkers. Wondering what to include and how to make the recommendation useful? Here’s how to write a reference letter for a teacher.

Want to make things even easier? Grab our free reference letter printable template, which walks you through the whole process. Just fill out the form on this page .

What is a reference letter?

How to write a letter of reference, reference letter example: principal for teacher, reference letter example: teacher for coworker.

Reference letters are just what they sound like: a testimonial about a person’s professional qualifications, abilities, and achievements. They’re written by someone who knows the applicant well and can speak to specifics about their career.

These days, most jobs don’t require reference letters since employers perform reference checks themselves. However, academia is different. Many teaching jobs require candidates to submit written letters of reference as part of their application packet. This is just one part of their overall evaluation of a candidate, of course. But these letters remain a key part of many teachers’ job searches.

Letter of Reference vs. Letter of Recommendation

These two terms are often used interchangeably, but reference letters are almost always specific to a job search. Students often need letters of recommendation for scholarships and college applications. If you need help writing a letter of recommendation for a student, check out these articles:

Review Reference Letter Samples

If you’ve never written a reference letter or you want to up your game, take a look at some samples first. One of our favorite ways to do it is to use AI like ChatGPT to generate some reference letter samples specific to your situation. You definitely don’t want to copy these word-for-word, but you might find some helpful phrases or get a better idea of the format you should use. We’ve included some sample letters below too.

Brainstorm Ideas First

Before you begin writing, do a quick brainstorming session and jot down your thoughts about these prompts:

• What three words first come to mind when you think of this teacher?
• List this person’s biggest strengths as an educator.
• List a few times when this teacher really impressed you.
• Has this person won any awards or accolades worth mentioning?
• What makes this teacher special compared to their peers?
• What would this teacher’s students say about them? What about parents or co-workers? (If you have examples, round them up to include in the letter.)

Personalize the Letter

If you can, try to write a letter that’s specific to the job the teacher needs a reference letter for. Find out what they’ll be doing in their new role or position so you can include the most relevant qualities in your recommendation. Some reference letters are more general, so it’s OK if you can’t personalize them to the job.

Ask the teacher if there’s anything specific they’d like you to mention. You may also ask if there’s anything they’d prefer to keep confidential. For instance, if the teacher has a disability, they may not want to disclose that information yet.

Write an Introduction

Introduce yourself and explain your relationship to the teacher you’re providing a reference for. Include information such as how long you’ve known them and whether you’re speaking as a colleague, coworker, mentor, or supervisor.

Verify Their Qualifications and Experience

In the next paragraph, speak to the teacher’s education, including any special certifications or professional development achievements. Mention any awards, honors, or accolades they’ve earned. You can keep this section fairly short; the teacher has likely listed all of this on their CV already. Your reference letter will just help verify these qualifications.

Highlight Their Best Qualities

In the body of your letter, write two or three paragraphs that really help identify what makes this teacher special. Don’t try to squeeze in everything you know; instead, think about what really helps the person you’re recommending stand out. For each paragraph, focus on one of these areas (or other relevant topics), choosing the two or three overall that seem most important for this person.

• Subject matter knowledge and expertise
• Pedagogy skills
• Student and/or parent relationships
• Professional development
• Community relations
• Communication skills
• Leadership roles
• School pride and loyalty
• Personal traits, such as passion, enthusiasm, dedication, creativity, etc.

Provide Specific Examples and Anecdotes

This is where you really have the chance to make your letter valuable to the candidate. It’s easy to describe a person as “passionate about recognizing diversity” or “excellent at differentiating learning.” Without examples, though, these are just words. Try to anchor each quality you mention with specific examples or anecdotes that back up those words. Here are a couple of examples:

• “Alana is passionate about recognizing and celebrating diversity in her classroom. She frequently draws on her strong community relationships to bring diverse speakers and cultural activities to her classroom. Last fall, she organized an incredibly popular school-wide Diversity Fair where students and their families were encouraged to share their own cultures and experiences and learn from each other. One parent noted, ‘I’ve lived in this community for three years, but this is the first time I really feel like I know my neighbors.’”
• “One of Jamie’s strongest qualities is their ability to differentiate learning for their students. They’re always willing to determine what’s keeping a student from doing their best and finding new ways to overcome challenges. For instance, Jamie was instrumental in helping our school implement text-to-speech software that assists struggling readers and those who have visual impairment. This leveled the playing field in their history and geography classes, helping students focus on the subject at hand instead of spending too much time deciphering text.”

Conclude With a Strong Endorsement

You’ve come all this way, so don’t fall short at the very end! This is the time to state your personal recommendation in no uncertain terms. Sum up your major points, and offer to provide more information if needed.

• “I’m pleased to recommend Alana Whitmore for an elementary teaching position at your school. Her commitment to diversity, creative classroom approaches, and compassion for students and fellow coworkers would make her an excellent addition to any education team. If you want to discuss her qualifications further, don’t hesitate to contact me.”

Write Professionally and Proofread Carefully

This is a business communication, so strive for a professional but warm tone overall. If it’s a paper letter, use the standard business letter format (on your school letterhead if you’re an administrator). In an email, be sure your signature includes contact information such as a phone number and school address.

Don’t forget to proofread! A letter riddled with spelling errors and grammar mistakes is unlikely to hold much sway with a hiring committee or selection panel. Use a program like Grammarly to help you edit your letter until you’re satisfied with the final version.

Dear Hiring Committee,

I am writing to enthusiastically recommend Alana Whitmore for any opportunity that may arise that aligns with her exceptional skills and dedication as an elementary school teacher. In my capacity as the principal of Maya Angelou Elementary, I have had the privilege of witnessing firsthand the invaluable contributions Alana has made to our school community.

Alana has worked here for seven years, three as a fifth-grade teacher and four in third grade. She came to us fresh from earning her teaching certification at Lancaster University, and continued her education over the last several years to earn her Master’s of Education in Curriculum Design and Development. She was honored with our district’s Teacher of the Year award in 2022 and was the keynote speaker at our state’s education conference in 2023.

Alana is an exemplary educator who consistently demonstrates a deep commitment to the academic and emotional growth of her students. Through her inventive teaching methods and personalized approach, she ensures that every child in her classroom is provided with opportunities to thrive and succeed. During a recent observation, I noted how she cleverly adapted her unit on volcanoes to embrace different learning styles. She provided choices like watching a video, reading an article, or listening to a short podcast to build background knowledge. Students individually chose the option they preferred, then used their knowledge to work with a partner to design a poster, write a report, or give a short presentation on the topic. Students were all engaged throughout the process, enjoying a measure of autonomy while still meeting the stated learning objectives.

Furthermore, Alana excels in building strong and collaborative relationships with parents and guardians. She understands the importance of fostering open communication and partnership between home and school, and she actively seeks opportunities to involve families in their child’s education. One parent reached out to me to share these thoughts: “Ms. Whitmore is the first teacher who seems to care about me as a parent and a person. She went out of her way to arrange a videoconference that met my hectic work schedule, and seemed genuinely interested in the suggestions I had for helping my son. Knowing that she really cares has made this school year so much better for us all.”

In addition to her effectiveness in the classroom and with parents, Alana is highly regarded by her colleagues for her collaborative spirit and willingness to share her expertise. Last year, she helped organize a very well-received professional development day, with a variety of sessions that allowed every teacher to find a subject that truly mattered to them. She serves as a mentor to one of our new teachers, who told me that Alana has helped him see how he can put his college educational theories into practice in the real world. Other teachers regularly share praise for Alana’s cooperative spirit, and she’s been awarded “Coworker of the Year” by our staff three years in a row.

Alana embodies the qualities of an exceptional educator: She is dedicated, passionate, and deeply invested in the well-being and success of her students. Her commitment to differentiation, parent relationships, and collaboration sets her apart as a truly outstanding teacher. I wholeheartedly recommend Alana Whitmore for any role or opportunity where her skills, expertise, and dedication can make a meaningful impact. Please feel free to contact me if you require any further information.

Gina Torres Principal, Maya Angelou Elementary

Dear Selection Committee,

I am writing to enthusiastically recommend Jamie Lin for any teaching position that may become available within your school. As a fellow teacher and colleague at Ridgemont High School, I have had the pleasure of working closely with Jamie and have witnessed firsthand their exceptional talents and dedication to the field of education.

Jamie came to our school as a teacher of history and geography in 2019, working with ninth- through twelfth-grade students each year since. Before joining our team, they earned their Master’s Degree in Education with a focus on diversity studies. During Jamie’s four years here, they have been nominated for Teacher of the Year three times and received the award in 2023. Jamie frequently speaks at educational conferences on subjects like cultural relevance and student diversity.

One of Jamie’s greatest strengths is their ability to foster diversity and inclusivity within the learning environment. Whether discussing historical events or exploring global cultures, Jamie ensures that all students feel valued, respected, and represented in the curriculum. They frequently draw on their strong community relationships to bring diverse speakers and cultural activities to the classroom. Speakers and cultural presentations have included representatives of several indigenous communities and local authors from a variety of backgrounds. They also invite community politicians and activists to debate key issues, while students observe and then question the speakers themselves.

In addition to their dedication to diversity, Jamie is a remarkably creative educator who consistently goes above and beyond to engage students in meaningful and thought-provoking learning experiences. They have a passion for project-based learning, teaching critical thinking and problem-solving by having students tackle real-world issues. Through their projects, Jamie’s students have painted cultural murals on the walls in the school courtyard, helped translate our school handbook and other documents into three different languages, and created clubs for fellow students interested in topics like history, geography, and global cultures. Jamie believes in demonstrating what you’ve learned in meaningful ways, and their students thrive in this environment.

Furthermore, Jamie excels at building strong community relationships both inside and outside the classroom. They actively collaborate with colleagues, parents, and community members to create a supportive and enriching learning environment that extends beyond the walls of the school. Last fall, Jamie organized an incredibly popular school-wide Diversity Fair where students and their families were encouraged to share their own cultures and experiences and learn from each other. One parent noted, “I’ve lived in this community for three years, but this is the first time I really feel like I know my neighbors.”

Overall, Jamie Lin is an exceptional educator who embodies the qualities of excellence, creativity, and community engagement. Their passion for teaching, dedication to diversity, and innovative approach to education make them an invaluable asset to any school community.

I wholeheartedly endorse Jamie Lin for any teaching position and am confident that they will continue to make a positive impact on the lives of their students and colleagues. Please feel free to contact me if you require any further information.

Today, we’re excited to share the first two models of the next generation of Llama, Meta Llama 3, available for broad use. This release features pretrained and instruction-fine-tuned language models with 8B and 70B parameters that can support a broad range of use cases. This next generation of Llama demonstrates state-of-the-art performance on a wide range of industry benchmarks and offers new capabilities, including improved reasoning. We believe these are the best open source models of their class, period. In support of our longstanding open approach, we’re putting Llama 3 in the hands of the community. We want to kickstart the next wave of innovation in AI across the stack—from applications to developer tools to evals to inference optimizations and more. We can’t wait to see what you build and look forward to your feedback.

Our goals for Llama 3

With Llama 3, we set out to build the best open models that are on par with the best proprietary models available today. We wanted to address developer feedback to increase the overall helpfulness of Llama 3 and are doing so while continuing to play a leading role on responsible use and deployment of LLMs. We are embracing the open source ethos of releasing early and often to enable the community to get access to these models while they are still in development. The text-based models we are releasing today are the first in the Llama 3 collection of models. Our goal in the near future is to make Llama 3 multilingual and multimodal, have longer context, and continue to improve overall performance across core LLM capabilities such as reasoning and coding.

State-of-the-art performance

Our new 8B and 70B parameter Llama 3 models are a major leap over Llama 2 and establish a new state-of-the-art for LLM models at those scales. Thanks to improvements in pretraining and post-training, our pretrained and instruction-fine-tuned models are the best models existing today at the 8B and 70B parameter scale. Improvements in our post-training procedures substantially reduced false refusal rates, improved alignment, and increased diversity in model responses. We also saw greatly improved capabilities like reasoning, code generation, and instruction following making Llama 3 more steerable.

*Please see evaluation details for setting and parameters with which these evaluations are calculated.

In the development of Llama 3, we looked at model performance on standard benchmarks and also sought to optimize for performance for real-world scenarios. To this end, we developed a new high-quality human evaluation set. This evaluation set contains 1,800 prompts that cover 12 key use cases: asking for advice, brainstorming, classification, closed question answering, coding, creative writing, extraction, inhabiting a character/persona, open question answering, reasoning, rewriting, and summarization. To prevent accidental overfitting of our models on this evaluation set, even our own modeling teams do not have access to it. The chart below shows aggregated results of our human evaluations across of these categories and prompts against Claude Sonnet, Mistral Medium, and GPT-3.5.

Preference rankings by human annotators based on this evaluation set highlight the strong performance of our 70B instruction-following model compared to competing models of comparable size in real-world scenarios.

Our pretrained model also establishes a new state-of-the-art for LLM models at those scales.

To develop a great language model, we believe it’s important to innovate, scale, and optimize for simplicity. We adopted this design philosophy throughout the Llama 3 project with a focus on four key ingredients: the model architecture, the pretraining data, scaling up pretraining, and instruction fine-tuning.

Model architecture

In line with our design philosophy, we opted for a relatively standard decoder-only transformer architecture in Llama 3. Compared to Llama 2, we made several key improvements. Llama 3 uses a tokenizer with a vocabulary of 128K tokens that encodes language much more efficiently, which leads to substantially improved model performance. To improve the inference efficiency of Llama 3 models, we’ve adopted grouped query attention (GQA) across both the 8B and 70B sizes. We trained the models on sequences of 8,192 tokens, using a mask to ensure self-attention does not cross document boundaries.

Training data

To train the best language model, the curation of a large, high-quality training dataset is paramount. In line with our design principles, we invested heavily in pretraining data. Llama 3 is pretrained on over 15T tokens that were all collected from publicly available sources. Our training dataset is seven times larger than that used for Llama 2, and it includes four times more code. To prepare for upcoming multilingual use cases, over 5% of the Llama 3 pretraining dataset consists of high-quality non-English data that covers over 30 languages. However, we do not expect the same level of performance in these languages as in English.

To ensure Llama 3 is trained on data of the highest quality, we developed a series of data-filtering pipelines. These pipelines include using heuristic filters, NSFW filters, semantic deduplication approaches, and text classifiers to predict data quality. We found that previous generations of Llama are surprisingly good at identifying high-quality data, hence we used Llama 2 to generate the training data for the text-quality classifiers that are powering Llama 3.

We also performed extensive experiments to evaluate the best ways of mixing data from different sources in our final pretraining dataset. These experiments enabled us to select a data mix that ensures that Llama 3 performs well across use cases including trivia questions, STEM, coding, historical knowledge, etc.

Scaling up pretraining

To effectively leverage our pretraining data in Llama 3 models, we put substantial effort into scaling up pretraining. Specifically, we have developed a series of detailed scaling laws for downstream benchmark evaluations. These scaling laws enable us to select an optimal data mix and to make informed decisions on how to best use our training compute. Importantly, scaling laws allow us to predict the performance of our largest models on key tasks (for example, code generation as evaluated on the HumanEval benchmark—see above) before we actually train the models. This helps us ensure strong performance of our final models across a variety of use cases and capabilities.

We made several new observations on scaling behavior during the development of Llama 3. For example, while the Chinchilla-optimal amount of training compute for an 8B parameter model corresponds to ~200B tokens, we found that model performance continues to improve even after the model is trained on two orders of magnitude more data. Both our 8B and 70B parameter models continued to improve log-linearly after we trained them on up to 15T tokens. Larger models can match the performance of these smaller models with less training compute, but smaller models are generally preferred because they are much more efficient during inference.

To train our largest Llama 3 models, we combined three types of parallelization: data parallelization, model parallelization, and pipeline parallelization. Our most efficient implementation achieves a compute utilization of over 400 TFLOPS per GPU when trained on 16K GPUs simultaneously. We performed training runs on two custom-built 24K GPU clusters . To maximize GPU uptime, we developed an advanced new training stack that automates error detection, handling, and maintenance. We also greatly improved our hardware reliability and detection mechanisms for silent data corruption, and we developed new scalable storage systems that reduce overheads of checkpointing and rollback. Those improvements resulted in an overall effective training time of more than 95%. Combined, these improvements increased the efficiency of Llama 3 training by ~three times compared to Llama 2.

Instruction fine-tuning

To fully unlock the potential of our pretrained models in chat use cases, we innovated on our approach to instruction-tuning as well. Our approach to post-training is a combination of supervised fine-tuning (SFT), rejection sampling, proximal policy optimization (PPO), and direct preference optimization (DPO). The quality of the prompts that are used in SFT and the preference rankings that are used in PPO and DPO has an outsized influence on the performance of aligned models. Some of our biggest improvements in model quality came from carefully curating this data and performing multiple rounds of quality assurance on annotations provided by human annotators.

Learning from preference rankings via PPO and DPO also greatly improved the performance of Llama 3 on reasoning and coding tasks. We found that if you ask a model a reasoning question that it struggles to answer, the model will sometimes produce the right reasoning trace: The model knows how to produce the right answer, but it does not know how to select it. Training on preference rankings enables the model to learn how to select it.

Building with Llama 3

Our vision is to enable developers to customize Llama 3 to support relevant use cases and to make it easier to adopt best practices and improve the open ecosystem. With this release, we’re providing new trust and safety tools including updated components with both Llama Guard 2 and Cybersec Eval 2, and the introduction of Code Shield—an inference time guardrail for filtering insecure code produced by LLMs.

We’ve also co-developed Llama 3 with torchtune , the new PyTorch-native library for easily authoring, fine-tuning, and experimenting with LLMs. torchtune provides memory efficient and hackable training recipes written entirely in PyTorch. The library is integrated with popular platforms such as Hugging Face, Weights & Biases, and EleutherAI and even supports Executorch for enabling efficient inference to be run on a wide variety of mobile and edge devices. For everything from prompt engineering to using Llama 3 with LangChain we have a comprehensive getting started guide and takes you from downloading Llama 3 all the way to deployment at scale within your generative AI application.

A system-level approach to responsibility

We have designed Llama 3 models to be maximally helpful while ensuring an industry leading approach to responsibly deploying them. To achieve this, we have adopted a new, system-level approach to the responsible development and deployment of Llama. We envision Llama models as part of a broader system that puts the developer in the driver’s seat. Llama models will serve as a foundational piece of a system that developers design with their unique end goals in mind.

Instruction fine-tuning also plays a major role in ensuring the safety of our models. Our instruction-fine-tuned models have been red-teamed (tested) for safety through internal and external efforts. ​​Our red teaming approach leverages human experts and automation methods to generate adversarial prompts that try to elicit problematic responses. For instance, we apply comprehensive testing to assess risks of misuse related to Chemical, Biological, Cyber Security, and other risk areas. All of these efforts are iterative and used to inform safety fine-tuning of the models being released. You can read more about our efforts in the model card .

Llama Guard models are meant to be a foundation for prompt and response safety and can easily be fine-tuned to create a new taxonomy depending on application needs. As a starting point, the new Llama Guard 2 uses the recently announced MLCommons taxonomy, in an effort to support the emergence of industry standards in this important area. Additionally, CyberSecEval 2 expands on its predecessor by adding measures of an LLM’s propensity to allow for abuse of its code interpreter, offensive cybersecurity capabilities, and susceptibility to prompt injection attacks (learn more in our technical paper ). Finally, we’re introducing Code Shield which adds support for inference-time filtering of insecure code produced by LLMs. This offers mitigation of risks around insecure code suggestions, code interpreter abuse prevention, and secure command execution.

With the speed at which the generative AI space is moving, we believe an open approach is an important way to bring the ecosystem together and mitigate these potential harms. As part of that, we’re updating our Responsible Use Guide (RUG) that provides a comprehensive guide to responsible development with LLMs. As we outlined in the RUG, we recommend that all inputs and outputs be checked and filtered in accordance with content guidelines appropriate to the application. Additionally, many cloud service providers offer content moderation APIs and other tools for responsible deployment, and we encourage developers to also consider using these options.

Deploying Llama 3 at scale

Llama 3 will soon be available on all major platforms including cloud providers, model API providers, and much more. Llama 3 will be everywhere .

Our benchmarks show the tokenizer offers improved token efficiency, yielding up to 15% fewer tokens compared to Llama 2. Also, Group Query Attention (GQA) now has been added to Llama 3 8B as well. As a result, we observed that despite the model having 1B more parameters compared to Llama 2 7B, the improved tokenizer efficiency and GQA contribute to maintaining the inference efficiency on par with Llama 2 7B.

For examples of how to leverage all of these capabilities, check out Llama Recipes which contains all of our open source code that can be leveraged for everything from fine-tuning to deployment to model evaluation.

What’s next for Llama 3?

The Llama 3 8B and 70B models mark the beginning of what we plan to release for Llama 3. And there’s a lot more to come.

Our largest models are over 400B parameters and, while these models are still training, our team is excited about how they’re trending. Over the coming months, we’ll release multiple models with new capabilities including multimodality, the ability to converse in multiple languages, a much longer context window, and stronger overall capabilities. We will also publish a detailed research paper once we are done training Llama 3.

To give you a sneak preview for where these models are today as they continue training, we thought we could share some snapshots of how our largest LLM model is trending. Please note that this data is based on an early checkpoint of Llama 3 that is still training and these capabilities are not supported as part of the models released today.

We’re committed to the continued growth and development of an open AI ecosystem for releasing our models responsibly. We have long believed that openness leads to better, safer products, faster innovation, and a healthier overall market. This is good for Meta, and it is good for society. We’re taking a community-first approach with Llama 3, and starting today, these models are available on the leading cloud, hosting, and hardware platforms with many more to come.
