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.

If you have questions after consulting this guide about how to cite, please contact your advisor/professor or the writing and communication center .

Why citing is important

It's important to cite sources you used in your research for several reasons:

• To show your reader you've done proper research by listing sources you used to get your information
• To be a responsible scholar by giving credit to other researchers and acknowledging their ideas
• To avoid plagiarism by quoting words and ideas used by other authors
• To allow your reader to track down the sources you used by citing them accurately in your paper by way of footnotes, a bibliography or reference list

About citations

Citing a source means that you show, within the body of your text, that you took words, ideas, figures, images, etc. from another place.

Citations are a short way to uniquely identify a published work (e.g. book, article, chapter, web site).  They are found in bibliographies and reference lists and are also collected in article and book databases.

Citations consist of standard elements, and contain all the information necessary to identify and track down publications, including:

• author name(s)
• titles of books, articles, and journals
• date of publication
• page numbers
• volume and issue numbers (for articles)

Citations may look different, depending on what is being cited and which style was used to create them. Choose an appropriate style guide for your needs.  Here is an example of an article citation using four different citation styles.  Notice the common elements as mentioned above:

Author - R. Langer

Article Title - New Methods of Drug Delivery

Source Title - Science

Volume and issue - Vol 249, issue 4976

Publication Date - 1990

Page numbers - 1527-1533

American Chemical Society (ACS) style:

Langer, R. New Methods of Drug Delivery. Science 1990 , 249 , 1527-1533.

IEEE Style:

R. Langer, " New Methods of Drug Delivery," Science , vol. 249 , pp. 1527-1533 , SEP 28, 1990 .

American Psychological Association   (APA) style:

Langer, R. (1990) . New methods of drug delivery. Science , 249 (4976), 1527-1533.

Modern Language Association (MLA) style:

Langer, R. " New Methods of Drug Delivery." Science 249.4976 (1990) : 1527-33.

What to cite

You must cite:

• Facts, figures, ideas, or other information that is not common knowledge

Publications that must be cited include:  books, book chapters, articles, web pages, theses, etc.

Another person's exact words should be quoted and cited to show proper credit 

When in doubt, be safe and cite your source!

Avoiding plagiarism

Plagiarism occurs when you borrow another's words (or ideas) and do not acknowledge that you have done so. In this culture, we consider our words and ideas intellectual property; like a car or any other possession, we believe our words belong to us and cannot be used without our permission.

Plagiarism is a very serious offense. If it is found that you have plagiarized -- deliberately or inadvertently -- you may face serious consequences. In some instances, plagiarism has meant that students have had to leave the institutions where they were studying.

The best way to avoid plagiarism is to cite your sources - both within the body of your paper and in a bibliography of sources you used at the end of your paper.

What is a Citation?

A citation identifies for the reader the original source for an idea, information, or image that is referred to in a work.

• In the body of a paper, the  in-text citation  acknowledges the source of information used.
• At the end of a paper, the citations are compiled on a  References  or  Works Cited  list. A basic citation includes the author, title, and publication information of the source. 

From:  Lemieux  Library,  University  of Seattle 

Why Should You Cite?

Quoting Are you quoting two or more consecutive words from a source? Then the original source should be cited and the words or phrase placed in quotes. 

Paraphrasing If an idea or information comes from another source,  even if you put it in your own words , you still need to credit the source.  General vs. Unfamiliar Knowledge You do not need to cite material which is accepted common knowledge. If in doubt whether your information is common knowledge or not, cite it. Formats We usually think of books and articles. However, if you use material from web sites, films, music, graphs, tables, etc. you'll also need to cite these as well.

Plagiarism is presenting the words or ideas of someone else as your own without proper acknowledgment of the source. When you work on a research paper and use supporting material from works by others, it's okay to quote people and use their ideas, but you do need to correctly credit them. Even when you summarize or paraphrase information found in books, articles, or Web pages, you must acknowledge the original author.

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 "

Welcome to a comprehensive guide on citing sources and formatting papers in the American Psychological Association style. Below are reference and in-text citation examples, directions on formatting your paper, and background information on the style.

What is APA?

APA stands for the American Psychological Association , which is an organization that focuses on psychology. They are responsible for creating this specific citation style. They are not associated with this guide, but all of the information here provides guidance to using their style and follows the Publication Manual of the American Psychological Association.

What is APA Citing?

APA style is used by many scholars and researchers in the behavioral and social sciences, not just psychology. There are other citation formats and styles such as MLA and Chicago citation style , but this one is most popular in the fields of science.

Following the same standard format for citations allows readers to understand the types of sources used in a project and also understand their components.

The information in this guide follows the 7th edition of the Publication Manual of the American Psychological Association . It outlines proper ways to organize and structure a research paper, explains grammar guidelines, and how to properly cite sources. This webpage was created solely by BibMe to help students and researchers focus on how to create APA citations.

The 7th edition of the Publication Manual was released in 2020. We address differences between the 6th and 7th editions at the end of this guide.

For more information, please consult the official Publication Manual .

We cite sources for many reasons. One reason is to give credit to the authors of the work you used to help you with your own research. When you use another person's information to help you with your project, it is important to acknowledge that individual or group. This is one way to prevent plagiarism. Another reason why we create citations is to provide a standard way for others to understand and possibly explore the sources we used. To learn more about citations, check out this page on crediting work . Also, read up on how to be careful of plagiarism .

What Does it Look Like?

There are two types of citations:

• In-text/Parenthetical citations: Those that are found in the body of a project are called in-text/parenthetical citations. They're added into a project when a direct quote or paraphrase has been added into your work. These citations only include the name(s) of the author(s), date, and page number(s), if applicable.
• References: Those that are found on the final part of a project are called references. They're are found in the reference list (sometimes called APA works cited by some teachers), which is at the end of the assignment. It includes the full information of all sources used in a project. These types of references show the author's name, date published, title, publisher, URL, and other key pieces of information.

Depending on the types of sources used for your project, the structure for each citation may look different. There is a certain format or structure for books, a different one for journal articles, a different one for websites, and so on. Scroll down to find the appropriate APA format structure for your sources.

Even though the structure varies across different sources, see below for a full explanation of in-text citations and reference citations.

Still wondering, "What is APA format?" To learn more about APA referencing, including access to the American Psychological Association\'s blog, formatting questions, & referencing explanations, click on this link for further reading on the style . To learn more about using the BibMe service (BibMe.com) to help build APA citation website references, see the section below titled, "Using the BibMe Online Writing Center to Create Citations for your Reference List or APA Bibliography."

Citing Basics

In-text citations overview.

When using a direct quote or paraphrasing information from a source, include an in-text or parenthetical citation into the body of your project, immediately following it.

An APA in-text citation may look similar to this:

Author's Last name (Year) states that "direct quote" or paraphrase (page number).

Parenthetical citations look like this:

"Direct quote" or paraphrase (Author's Last name, Year, Page number).

These types of APA citations always have the author and the date together.

Only direct quotes need a page number. For paraphrased information, it isn't necessary, but helpful for the reader.

See the section below titled, "In-Text or Parenthetical Citations," for a full explanation and instructions.

Full References Overview

Each source used in your project is listed as a full citation on the APA reference page, which is usually the last part of a project.

The structure for each citation is based on the type of source used. Scroll down to see APA format examples of some common source formats.

Most print and offline citations include the following pieces of information, commonly in this order:

Author's Last name, First initial. Middle initial. (Date published). Title of source . Publisher.

Most online citations include the following pieces of information, commonly in this order:

Author's Last name, First Initial. Middle initial. (Date published). Title of source . URL

To see how to format each section, scroll down to the appropriate areas of this guide. There is a section on authors, one on publication dates, another on titles, publishers, and on online information.

To determine the exact APA citation format for your full citations, scroll down to the section titled, "Common Examples."

For a detailed explanation on formatting your reference list, scroll down to the section titled, "Your Reference List."

Here's a quick snapshot of the basics:

All in-text citations included throughout the paper should have a corresponding full reference at the end of the project.

Full references go on their own page at the end of a project. Title the page "References"

References are listed in alphabetical order by the first word in the reference (usually the author's last name, sometimes the title).

• If the reference begins with the words A , An , or The , ignore them and alphabetize the reference by the word following it.

If you're looking for an easy way to create your references and citations, use BibMe's free APA citation machine, which automatically formats your sources quickly and easily.

Citation Components

How to structure authors.

Authors are displayed in reverse order: Last name, First initial. Middle initial. End this information with a period.

APA format example:

Kirschenbaum, M. A.

In an APA citation, include all authors shown on a source. If using the BibMe APA citation builder, click "Add another contributor" to add additional author names. Our free citation creator will format the authors in the order in which you add them.

Multiple authors, same last name:

If your reference list has multiple authors with the same last name and initials, include their first name in brackets.

Brooks, G. [Geraldine]. (2005). March . Viking.

Brooks, G. [Gwendolyn]. (1949). Annie Allen . Harper & Brothers.

When no author is listed, exclude the author information and start the citation with the title followed by the year in parentheses.

When citing an entire edited book in APA format, place the names of editors in the author position and follow it with Ed. or Eds. in parentheses. See below for examples of citing edited books in their entirety and also APA citation format for chapters in edited books.

Comparison chart:

Use this handy chart to determine how to format author names in citations and references.

How to Structure Publication Dates

General structure is:

• Year, Month Day
• Example: 1998, March 22

Place the date that the source was published in parentheses after the name of the author. In APA format for periodicals, include the month and day as well. If no date is available, place n.d. in parentheses, which stands for no date. For more details, see Section 9.14 of the Publication Manual .

How to Structure the Title

For book titles: Only capitalize the first letter of the first word in the title and the same for the subtitle. Capitalize the first letter for any proper nouns as well. Place this information in italics. End it with a period.

Gone with the wind.

For articles and chapter titles: Only capitalize the first letter of the first word in the title and the same for the subtitle. Capitalize the first letter for any proper nouns as well. Do not italicize the title or place it in quotation marks. End it with a period.

The correlation between school libraries and test scores: A complete overview.

For web pages on websites: Same as above. The web page title is italicized.

Simmons, B. (2015, January 9). The tale of two Flaccos . Grantland. http://grantland.com/the-triangle/the-tale-of-two-flaccos/

For magazine, journal, and newspaper titles: Each important word should start with a capital letter.

The Boston Globe

If you believe that it will help the reader to understand the type of source, such as a brochure, lecture notes, or an audio podcast, place a description in brackets directly after the title. Only capitalize the first letter.

New World Punx. (2014, February 15). A state of trance 650 [Audio file]. https://soundcloud.com/newworldpunx/asot650utrecht

How to Structure Publication Information

Publisher Location

In previous editions of the publication manual, books and sources that were not periodicals indicated the city and state of publication. However, in the 7th edition, the location of publication is no longer given except “for works associated with specific locations, such as conference presentations” (p. 297).

For conference presentations, give the city, state/province/territory, and country. If in the US, abbreviate the state name using the two-letter abbreviation. Place a colon after the location.

• Philadelphia, PA:
• Rotterdam, Netherlands:

Periodical Volume and Number

For journals, magazines, newspapers, and other periodicals, place the volume number after the title. Italicize this information. Place the issue number in parentheses and do not italicize it. Afterwards, include page numbers.

Journal of Education for Library and Information Science, 57 (1), 79-82.

If you're citing a newspaper article, include p. or pp. before the page numbers.

How to Structure the Publisher

The names of publishers are not necessary to include for newspapers, magazines, journals, and other periodicals.

For books and other sources: It is not necessary to type out the name of the publisher exactly as it is shown on the source. Use a brief, but understandable form of the publisher's name. Exclude the terms publishers, company, and incorporated. Include Books and Press if it is part of the publisher's name. End this information with a period (See Section 9.29 in the Publication manual for more details).

Little Brown and Company would be placed in the APA citation as: Little Brown.

Oxford University Press would be placed in the citation as: Oxford University Press.

How to Structure Online Sources

For sources found online:

• include the URL at the end of the citation
• do not place a period after the URL

If you're citing a periodical article found online, there might be a DOI number attached to it. This stands for Direct Object Identifier. A DOI, or digital object identifier, is a unique string of numbers and letters assigned by a registration agency. The DOI is used to identify and provide a permanent link to its location on the Internet. The DOI is assigned when an article is published and made electronically. If your article does indeed have a DOI number, use this instead of the URL as the DOI number is static and never changes. If the source you're citing has a DOI number, after the publication information add a period and then http://dx.doi.org/10.xxxx/xxxxxx. The x's indicate where you should put the DOI number. Do not place a period after the DOI number. See sections 9.35-36 in the Publication manual for more details.

If you're using the automatic BibMe APA reference generator, you will see an area to type in the DOI number.

Lobo, F. (2017, February 23). Sony just launched the world's fastest SD card. http://mashable.com/2017/02/23/sony-sf-g-fastest-sd-card/?utm_cid=mash-prod-nav-sub-st#ErZKV8blqOqO

Citations and Examples

Citations for print books.

Finney, J. (1970). Time and again . Simon and Schuster.

Looking for an APA formatter? Don't forget that the BibMe APA citation generator creates citations quickly and easily.

Notes: When creating an APA book citation, keep these in mind:

• Capitalize the first letter of the first word of the title and any subtitles, as well as the first letter of any proper nouns.
• The full title of the book, including any subtitles, should be stated and italicized.

Citations for Edited Books

Most edited books state on the cover or title page that they are edited by an author or multiple authors. The format is the same as a print book, except the editor's name is in the author's position. Include a parentheses afterwards with the abbreviation (Ed.) for an edited book by one author or (Eds.) for an edited book with two or more authors.

Editor, F. M. (Ed.). (Year published). Title of edited book . Publisher.

Gupta, R. (Ed.). (2003). Remote sensing geology . Springer-Verlag.

Citations for Chapters in Edited Books

Some edited books contain chapters written by various authors. Use the format below to cite an author's individual chapter in an edited book.

Chapter author's Last name, F. M. (Year published). Title of chapter. In F. M. Last name of Editor (Ed.), Title of book (p. x or pp. x-x). Publisher.

Notice that for APA style, the title of the chapter is not italicized, while the title of the book is. In addition, the chapter author's name is reversed at the beginning of the reference, but the editor's name is written in standard order.

Longacre, W. A., & Ayres, J. E. (1968). Archeological lessons from an Apache wickiup. In S. R. Binford & L. R. Binford (Eds.), Archeology in cultural systems (pp. 151-160). https://books.google.com/books?id=vROM3JrrRa0C&lpg=PP1&dq=archeology&pg=PR9#v=onepage&q=archeology&f=false

In the above example, Longacre and Ayers are the authors of the individual chapter and Binford & Binford are the editors of the entire book.

Citing an E-book from an E-reader

E-book is short for "electronic book." It is a digital version of a book that can be read on a computer, e-reader (Kindle, Nook, etc.), or other electronic devices. Include the DOI or URL if one exists for the e-book.

Author's Last name, F. M. (Year published). Title of work . https://doi.org/10.xxxx/xxxxxx or URL

https://doi.org/10.xxxx/xxxxxx is used when a source has a DOI number. If the e-book you're citing has a DOI number, use it in the APA citation. DOIs are preferred over URLs.

How to cite in APA (an e-book example):

Eggers, D. (2008). The circle . https://www.amazon.com

Citing an E-book Found in a Database and Online

Use this format when citing an e-book that is either found on a website, or found on a subscription database. APA formatting for this is very similar to the structure of a print book. The only difference? Instead of the publisher information, include the DOI number or URL.

Author's Last name, F. M. (Year published). Title of work . https://doi.org/10.xxxx/xxxxxx OR URL

When citing an online book or e-book, keep in mind:

• A DOI (digital object identifier) is an assigned number that helps link content to its location on the Internet. It is therefore important, if one is provided, to use it when creating a citation. In place of the x's in the DOI format, place the 10 digit DOI number.
• Notice that for e-books, publication information is excluded from the citation.

Sayre, R. K., Devercelli, A. E., Neuman, M. J., & Wodon, Q. (2015). Investment in early childhood development: Review of the world bank's recent experience . https://doi.org/10.1596/978-1-4648-0403-8

Citations for Chapters in E-books

Need to cite a chapter in an e-book? No problem! Citing a chapter in an e-book is very similar to citing a chapter in a print book. Instead of including the publisher information, include a DOI number (if one is displayed) or the URL.

Chapter author's Last name, F. M. (Year published). Title of chapter. In F. M. Last name of Editor (Ed.), Title of book (p. x or pp. x-x). https://doi.org/10.xxxx/xxxxxx or URL

Epstein W. M. (1999). The ineffectiveness of psychotherapy. In C. Feltham (Ed.), Controversies in psychotherapy and counselling (pp. 65-73). https://doi.org/10.4135/9781446217801.n8

Citations for Websites

How to cite a web page on a website in APA:

Author's Last name, F. M. (Year, Month Day published). Title of article or page . Site Name. URL

APA website citation example:

Citing a web page with a group author:

Group Name. (Year, Month Date published). Title of wep page . Saite Name included if different from Group Name. URL

Centers for Disease Control and Prevention. (2020, February 3). Be prepared to stay safe and healthy in winter . https://www.cdc.gov/features/winterweather/index.html

National Park Service. (n.d.). Enchanting landscapes beneath the parks . https://www.nps.gov/subjects/caves/index.htm

Note: "n.d." stands for "no date" and is used when there is no publication date.

The above follows Section 10.16 of the Publication manual.

Citations for Journal Articles Found in Print

Today, most journal articles are found online, but you may be lucky enough to score a copy of a print version for your research project. If so, use the structure below for your reference:

Author's Last name, F. M. (Year published). Article title. Periodical Title, Volume (Issue), pp.-pp.

Notice that the article's title is only capitalized at the beginning. If there are any proper nouns or subtitles, capitalize the first letter for those words as well. The journal article's title and the volume number are both italicized. In addition, the title of the journal is in title case form (all important words are capitalized).

Nevin, A. (1990). The changing of teacher education special education. Teacher Education and Special Education: The Journal of the Teacher Education Division of the Council for Exceptional Children,13 (3-4), 147-148.

Citations for Journal Articles Found Online

Databases are a popular place to find high quality journal articles. These references are formatted the same way as the print versions, except the DOI or URL is included at the end. If the article has a corresponding DOI number, use it instead of the URL. No URL? Use the homepage of the journal's website for the URL. See Section 10.1 in the Publication manual for additional examples.

Author's Last name, F. M. (Year published). Title of article. Title of Journal, volume number (issue number), page range. https://doi.org/10.xxxx/xxxxxx OR URL

Spreer, P., & Rauschnabel, P. A. (2016). Selling with technology: Understanding the resistance to mobile sales assistant use in retailing. Journal of Personal Selling & Sales Management, 36 (3), 240-263. https://doi.org/10.1080/08853134.2016.1208100

Notes: When creating your online journal article citation, keep in mind:

• This citation style does NOT require you to include the date of access/retrieval date or database information for electronic sources.
• Use the URL of the journal homepage if there is no DOI assigned and the reference was retrieved online. * If the journal article has a DOI number assigned to it, include that number in the citation instead of a URL.
• Don't forget, our free BibMe APA generator is simple to use! Check out BibMe Plus while you're at it! If you have a noun , conjunction , or preposition out of place, we'll flag it and offer suggestions for quick writing fixes!

Citations for a Newspaper Article in Print

Similar to journal articles, most individuals use online newspaper articles for research projects. However, if you're able to get your hands on a print version, use this structure for your reference:

Author's Last name, F. M. (Year, Month Day of Publication). Article title. Newspaper Title, pp. xx-xx.

Rosenberg, G. (1997, March 31). Electronic discovery proves an effective legal weapon. The New York Times, p. D5.

Notes: When creating your newspaper citation, keep in mind:

• Begin page numbers with p. (for a single page) or pp. (for multiple pages).
• Even if the article appears on non-consecutive pages, include all page numbers, and use a comma to separate them. Example: pp. C2, C5, C7-C9.
• Include the full date of publication, not just the year like in most references.

Citations for Newspapers found Online

Use this structure when referencing a newspaper article found on a website or database:

Author's Last name, F. M. (Year, Month Day of Publication). Title of article. Title of Newspaper. URL of newspaper's homepage

Rosenberg, G. (1997, March 31). Electronic discovery proves an effective legal weapon. The New York Times. http://www.nytimes.com

Notes: When citing a newspaper, keep in mind:

• If the article was found on the newspaper's website, include the URL for the newspaper's homepage. For databases, include whatever URL is provided.
• Multiple lines: If the URL runs onto a second line, only break URL before punctuation (except for http://).
• This style does NOT require you to include the date of access for electronic sources. If you discovered a newspaper article via an online database, the database's information is NOT required for the citation either. If you're using the BibMe APA formatter, we make it easy for you by only including what you need in your references!

Citations for Magazines

Citing a magazine article in print:

Author's Last name, F. M. (Year, Month of publication). Article title. Magazine Title, Volume (Issue), page range.

APA format citation:

Tumulty, K. (2006, April). Should they stay or should they go? Time, 167 (15), 3-40.

Notes: When citing a magazine, keep in mind:

• You can find the volume number with the other publication information of the magazine.
• You can typically find page numbers at the bottom corners of a magazine article.
• If you cannot locate an issue number, simply don't include it in the citation.

Citing a magazine article found online:

Author's Last name, F. M. (Year, Month of publication). Article title. Magazine Title, Volume (Issue). URL

Tumulty, K. (2006, April). Should they stay or should they go? Time, 167 (15). http://content.time.com/time/magazine/article/0,9171,1179361,00.html

Notes: When creating an online magazine citation, keep in mind:

*The volume and issue number aren't always on the same page as the article. Check out the other parts of the website before leaving it out of the citation.

Citations for Blogs

Blogs are found on websites and display continuously updated content and posts by a single author, group, or company. A blog shows news updates, ideas, information, and many other types of entries. Similar to journal entries, a blog begins with the date the information was added followed by the content.

If you’re wondering how to cite a blog entry, look no further! Citing a blog is very similar to citing a website.

Citing a blog post:

Last name of Author, First initial. Middle initial. (Year, Month Day blog post was published). Title of blog post. Title of Blog . URL

Citations for Encyclopedia and Dictionary Entries

Encyclopedia/Dictionary in print:

Author's Last name, F. M. (Publication Year). Entry title. In F. M. Last name of Editor (Ed.), Title of encyclopedia or dictionary (pp. xx-xx). Publisher.

Kammen, C., & Wilson, A. H. (2012). Monuments. Encyclopedia of local history . (pp. 363-364). AltaMira Press.

Encyclopedia/Dictionary online with author(s) :

Author’s Last name, F. M. (Publication Year or n.d.). Entry title. In F. M. Last name of Editor (Ed.), Title of encyclopedia or dictionary . Publisher. Retrieved date, from URL

Encyclopedia/Dictionary online with group author:

Publisher or group name (Publication Year or n.d.). Entry title. In Title of encyclopedia or dictionary . Retrieved date, from URL

Merriam-Webster. (n.d.). Taciturn. In Merriam-Webster.com dictionary . Retrieved February 10, 2020, from https://www.merriam-webster.com/dictionary/taciturn

If an entry looks like it goes through many updates, use “n.d.” as the publication date and show the date you retrieved it. If using an archived version, no retrieval date is needed.

How to Reference a Lecture

This style of reference would be used if you were citing a set of notes from a lecture (e.g., PowerPoint or Google slides provided by your instructor).

Citing online lecture notes or presentation slides:

Author's Last name, F. M. (Publication year). Name or title of lecture [Lectures notes or PowerPoint slides]. URL

Saito, T. (2012). Technology and me: A personal timeline of educational technology [PowerPoint slides]. http://www.slideshare.net/Bclari25/educational-technology-ppt

Tip: If you want to cite information from your own personal notes from a lecture, this is considered personal communication. The notes may not be available online for others outside of the class to access. Refer to it only in the body of your essay or project. You can follow the style guide for personal communication available in the Interview section.

Citing Social Media

Social media is everywhere, even in research projects. Many influencers post thoughts, inspirational quotes, and intriguing stories in their profiles.

If you need to cite a post from a social media platform, use this structure:

Last name, F. M. or Group Name who posted the content [@Username]. (Year, Month Day posted). First 20 words of the post [Format]. Social Media Site Name. URL

A retrieval date (date you saw the page) is needed for profile pages since the contents are likely to change over time (e.g., Instagram profile, Facebook page etc.). The structure for that is:

Last name, F. M. or Group Name who posted the content [@Username]. (n.d.). Tweets or Home [Format]. Social Media Site Name. Retrieved from month day, year, URL

Some things to keep in mind:

• If the name of the individual or group is unknown, begin the citation with the handle and remove the brackets.
• If the post only includes an image or video without any text, instead of including the first 40 words of the post provide a description of the post and place it in brackets: [video of a NASA rocket leaving the atmosphere].
• The format, in brackets, can be [Tweet], [Facebook status update], [Facebook page], [Instagram photo], [Instagram video], or for a Reddit post, use [Online forum comment].

Since this citation style is commonly used in science-related disciplines, it makes sense that many students and scholars include tables in their projects.

It's a good idea to include a table in your project when:

• There is a good amount of quantitative information
• A table would promote understanding

Do not write out the information from the table in the text of your paper. Including the same information in two spots is repetitive. Either type out the quantitative information in your paper or use a table.

If you choose to include a table, make sure to:

• Refer to it in the text and provide a brief overview or snapshot of its contents.
• Refer to the table in the text using numbers. For example, "Table 3 shows the countries with the highest amount of spending per pupil."
• Every table should be numbered. The table mentioned closest to the beginning of the paper should be Table 1. The next table referred to in the paper is Table 2.
• If you're submitting your project for publication in a journal or elsewhere, place all of your tables, in number order, at the end of your project, after the reference list. If you're submitting your project for a class, most professors prefer tables to be situated close to mentions in text. Ask your teacher or professor which one they prefer.
• Each table needs a title. The title of the table should match the content displayed in it. Create a name for your table that is easy to understand. Italicize the title and capitalize the first letter of all major key words.
• Capitalize the first letter of every important word.
• Your table can either be single or double spaced. Keep the spacing in tables consistent throughout your project.
• A general note provides an overview of any information related to the table as well as an explanation of any abbreviations or unique characters. If you reproduced any portion of the table, include that information in the general note as well. Begin your general note with "Note." in italics and ending with period.
• A specific note explains information in a row, column, or individual cell. Place a tiny letter in the top right corner of the area to specify, and include information regarding it in the note below.
• A probability note displays the number of possibilities in the table. Use an asterisk symbol in the table, and show the probability in the notes.

Sample Table:

Prior to adding your table into your paper, use this handy checklist to confirm you have all of the requirements:

__ Is it necessary to include the table?

__ Are only horizontal lines included?

__ Did you include a simple, straightforward title? Is it in italics?

__ Did you use either single spaces or double spaces? APA paper format requires you to keep your tables consistent across your project.

__ Are column headings included?

__ Are notes included below the table to provide understanding? Are the notes in the proper order? Start with general notes, then include specific notes, and end with probability notes.

__ Did you refer to the table in the written portion of your paper?

Still have questions? See Chapter 7 of the Publication manual .

In-Text and Parenthetical Citations

What is an in-text citation or parenthetical citation.

The purpose of in-text and parenthetical citations is to give the reader a brief idea as to where you found your information, while they're in the middle of reading or viewing your project. You may include direct quotes in the body of your project, which are word-for-word quotes from another source. Or, you may include a piece of information that you paraphrased in your own words. These are called parenthetical citations. Both direct quotes and paraphrased information include a citation next to it. You also need to include the full citation for the source in the reference list, which is usually the last item in a project.

In-Text Citations for Direct Quotes

In-text and parenthetical citations are found immediately following any direct quotes or paraphrases. They should include the page number or section information to help the reader locate the quote themselves.

Buck needed to adjust rather quickly upon his arrival in Canada. He stated, "no lazy, sun-kissed life was this, with nothing to do but loaf and be bored. Here was neither peace, nor rest, nor a moment's safety" (London, 1903, p. 25).

Paraphrased Information

When taking an idea from another source and placing it in your own words (a paraphrase), it is not necessary to include the page number, but you can add it if the source is large and you want to direct readers right to the information.

At the time, papyrus was used to create paper, but it was only grown and available in mass quantities in Egypt. This posed a problem for the Greeks and Romans, but they managed to have it exported to their civilizations. Papyrus thus remained the material of choice for paper creation (Casson, 2001).

How to Format In-Text and Parenthetical Citations

An in-text citation in APA displays the author's name directly in the sentence, or text, of the paper. Always place the year directly after the author's name. Authors and dates stick together like peanut butter and jelly! If you're citing a direct quote, place the page number at the end of the quote.

Parenthetical citations display the author's name and year in parentheses after a quote or paraphrase. If you're citing a direct quote, include the page number as well. If you're paraphrasing, it is up to you whether or not you'd like to include a page number.

Example of various ways to cite in the body of a project:

Smith (2014) states that, "the Museum Effect is concerned with how individuals look at a work of art, but only in the context of looking at that work along with a number of other works" (p. 82). "The Museum Effect is concerned with how individuals look at a work of art, but only in the context of looking at that work along with a number of other works" (Smith, 2014, p. 82).

If your source has two authors, always include both names in each in-text or parenthetical citation.

Example: (Franks & Beans, 2019)

If your source has three or more authors, only include the first author's name and follow it with et al.

Example: (Gilley et al., 2015)

If your source was written by a company, organization, government agency, or other type of group, include the group's name in full in the first in text or parenthetical citation. In any APA citations following it, it is acceptable to shorten the group name to something that is simple and understandable.

1st citation:

(American Eagle Outfitters /[AEO/], 2017)

2nd and subsequent citations:

(AEO, 2017)

Your Reference List

The listing of all sources used in your project are found in the reference list, which is the last page or part of a project. Included in this reference list are all of the sources you quoted or paraphrased in the body of your paper. This means that every reference found in the reference list should have a matching in-text or parenthetical citation in your project. Where there is one, there has to be the other. Here are general guidelines:

• Your reference page in APA should be titled "References"
• Place the title in the center of the page and bold it.
• It is not necessary to include personal communications in the reference list, such as personal emails or letters. These specific sources only need in-text citations, which are found in the body of your project.
• All references are listed in alphabetical order by the author's last name.
• The entire page should be double spaced.
• Use a hanging indent for all citations. The first line of each citation needs to be flush against the left margin. Any additional lines are indented in a half inch.
• If you have two sources by the same author, place them in order by the year of publication.
• Refer to the section titled, "How to Structure the Title," for rules regarding capitalization of source titles.

Thompson, H. S. (1971). Fear and loathing in Las Vegas: A savage journey to the heart of the American dream . Random House.

Thompson, H. S. (1998). The rum diary . Simon & Schuster.

If there are multiple sources with the same author AND same publication date, place them in alphabetical order by the title.

Dr. Seuss. (1958). The cat in the hat comes back . Random House.

Dr. Seuss. (1958). Yertle the turtle . Random House.

If a source does not have an author, place the source in alphabetical order by the first main word of the title.

How to Format Your Paper in APA:

Need to create APA format papers? Follow these guidelines:

In an APA style paper, the font used throughout your document should be in Times New Roman, 12 point font size. The entire document should be double spaced, even between titles and APA headings. Margins should be 1 inch around the entire document and indent every new paragraph using the tab button on your keyboard. See Chapter 2 of the Publication manual for more details on paper formatting.

Place the pages in the following order:

• Title page (Page 1)
• Abstract page (page 2)
• Text or body of research paper (start on page 3)
• Reference list
• Page for tables (if necessary)
• Page for figures (if necessary)
• Appendices page (if necessary)

Page numbers: The title page counts as page 1. Number subsequent pages using Arabic numbers (1, 2, 3, 4...).

Title Page in APA

Your title page should grace the front cover of your paper. It's sometimes called an APA cover page. Included on this page are seven items:

• Page number
• Title of paper
• Name of authors
• Affiliation; name of your school or institution
• Course name
• Instructor's name
• Date paper is due

What is a running head?

The running head shows the title of your paper. It is only required for professional papers (e.g., dissertations, journal submissions, etc.).

Student papers do not need a running head (but do need the page number).

If you use one, place the running head in the top left corner of your project and place it in capital letters. Use your word processor's "header" option. It will automatically place your running head in the appropriate position, against the left margin.

Across from the running head, against the right margin, include the page number. The APA title page is 1.

Title page example:

• QUALITY LIBRARY PROGRAMS

Microsoft Word, Google Docs, and many other word processing programs allow you to set up page numbers and a repeated running head. Use these tools to make this addition easier for you!

Need help determining the title of your paper? Keep it simple and straight to the point. Exclude unnecessary terms such as "An Analysis of...." or "A Study of..." If your paper ends up being digitized and added to your school's research collection or a research database, a simple and effective title will help researchers locate it. It is recommended to keep it under 12 words and avoid abbreviations.

Order | Element | Format & Notes --- | --- | --- 0 | All elements, except page number | Centered, double-spaced lines 1 | Page number | Place “1” in the upper right corner of the page. Professional papers only: Include a running head. 2 | Title of paper | 3-4 lines from the top of the page; bolded, and title case 3 | Name of author(s) | Two double-spaced lines under the title. No font formatting (no bold italics, underline). Exclude any titles (such as Dr. or Ms.) and degrees (such as PhD). List all contributors; if there is more than one include the word “and” between the second to last and last names. 4 | Affiliation (school, department, etc.) | No font formatting. Usually includes the name of your department and university. 5 | Course name | No font formatting. Write the course name and number on your class materials: ENG 102, JPN301. 6 | Instructor | No font formatting. Show their name as they prefer, including titles and degrees. 7 | Date paper is due | Month Day, Year. Example: February 14, 2020

Levels of Headings:

There are a lot of rules to follow when it comes to styling the header and title page, but there are even more rules when it comes to styling the various headings and sections in your research paper.

There are five sizes and styles, and they follow a top down approach.

In most cases, science-related papers and case studies have three sections: Method, Results, and Discussion. These three sections are considered “Level 1” and are aligned in the center of the page and in bold. Additional sections of the paper are styled as follows:

Overview of Levels

Level | Formatting --- | --- 1 | Center and bold. Use title case. 2 | Against the left margin and in bold. Use title case. Begin the next sentence on the next line, indented half an inch from the left margin. 3 | Against the left margin in bold and italics. Use title case. Begin your next sentence on the next line, and indented half an inch from the left margin. 4 | Indented half an inch from the left. Is in bold. Use title case. Begin your next sentence on the same line and immediately following the heading. 5 | Indented half an inch from the left. Is in bold and italics. Use title case. Begin your next sentence on the same line and immediately following the heading.

We’ve included a visual below to help you make sense of the five headings. Keep in mind, you do not need to have all five headings in your paper. You may only use the top two or three. It depends on the types of sections your paper includes.

Background Information and History of APA:

The American Psychological Association was founded in 1892 at Clark University in Worcester, Massachusetts. APA style format was developed in 1929 by scholars from a number of different scientific fields and backgrounds. Their overall goal was to develop a standard way to document scientific writing and research.

Since its inception, the Style Manual has been updated numerous times and it is now in its 7th edition (2020). The previous 6th edition was released in 2009. In 2012, APA published an addition to their 6th edition manual, which was a guide for creating an APA style citation for any type of electronic resource.

Today, there are close to 118,000 members. There is an annual convention, numerous databases, and journal publications. Some of their more popular resources include the database, PsycINFO, and the publications, Journal of Applied Psychology and Health Psychology .

Changes Between the 6th and 7th Editions

Below is a selection of notable citing differences between the two editions.

For journal articles with a DOI number , include the DOI as a URL.

6th edition example:

Lee, C.-H., & Mackinnon, R. (2019). Voltage sensor movements during Hyperpolarization in the HCN Channel. Cell Studies . doi: 10.1016/j.cell.2019.11.006

7th edition example:

Lee, C.-H., & Mackinnon, R. (2019). Voltage sensor movements during Hyperpolarization in the HCN Channel. Cell Studies . https://doi.org/10.1016/j.cell.2019.11.006

For ebooks , you no longer need to identify the format.

Murakami, H. (2014). Kafka on the shore [Kindle].

Murakami, H. (2014). Kafka on the shore .

Full book references no longer need to show where the publisher is located.

Murakami, H. (2014). Kafka on the shore . London: Vintage Publishing.

Murakami, H. (2014). Kafka on the shore . Vintage Publishing.

In-text citations for sources with more than 3 authors can use the notation “et al.” for brevity.

(first author’s name et al., year published)

(Anaydike, Braga, Talfah, Gonzalez, 1980)

(Anaydike et al., 1980)

When including a website URL , do not include the words “Retrieved from” before the URL cited.

Elan, P. (2019, December 6). 'A reflection of inner life': show explores history of the hoodie. The Guardian . Retrieved from https://www.theguardian.com/fashion/2019/dec/06/a-reflection-of-inner-life-show-explores-history-of-the-hoodie

The citing format for tables and figures are now the same. For both, indicate a table number and name at the top, and a note at the bottom.

Here are a few important paper formatting changes: * Running head is only required for professional (not student) papers * Only a single space should be placed after punctuation. * The new style version endorses the use of the singular “they” as an option for a gender neutral pronoun. * The 7th edition promotes the use of “they” as a singular, gender-neutral pronoun. * In addition to the paper title, author name, and institutional affiliation, a cover page for a student paper should also have the course, instructor name, and due date

Appropriate Level of Citation

The number of sources you cite in your paper depends on the purpose of your work. For most papers, cite one or two of the most representative sources for each key point. Literature review papers, however, typically include a more exhaustive list of references.

Provide appropriate credit to the source (e.g., by using an in-text citation) whenever you do the following:

• paraphrase (i.e., state in your own words) the ideas of others
• directly quote the words of others
• refer to data or data sets
• reprint or adapt a table or figure, even images from the internet that are free or licensed in the Creative Commons
• reprint a long text passage or commercially copyrighted test item

Avoid both undercitation and overcitation. Undercitation can lead to plagiarism and/or self-plagiarism . Overcitation can be distracting and is unnecessary.

For example, it is considered overcitation to repeat the same citation in every sentence when the source and topic have not changed. Instead, when paraphrasing a key point in more than one sentence within a paragraph, cite the source in the first sentence in which it is relevant and do not repeat the citation in subsequent sentences as long as the source remains clear and unchanged.

Figure 8.1 in Chapter 8 of the Publication Manual provides an example of an appropriate level of citation.

Determining the appropriate level of citation is covered in the seventh edition APA Style manuals in the Publication Manual Section 8.1 and the Concise Guide Section 8.1

Research Paper Citation

Research paper citation refers to the act of acknowledging and referencing a previously published work in a scholarly or academic paper . When citing sources, researchers provide information that allows readers to locate the original source, validate the claims or arguments made in the paper, and give credit to the original author(s) for their work.

The citation may include the author’s name, title of the publication, year of publication, publisher, and other relevant details that allow readers to trace the source of the information. Proper citation is a crucial component of academic writing, as it helps to ensure accuracy, credibility, and transparency in research.

How to Cite Research Paper

Title: scalable diffusion models with transformers.

Abstract: We explore a new class of diffusion models based on the transformer architecture. We train latent diffusion models of images, replacing the commonly-used U-Net backbone with a transformer that operates on latent patches. We analyze the scalability of our Diffusion Transformers (DiTs) through the lens of forward pass complexity as measured by Gflops. We find that DiTs with higher Gflops -- through increased transformer depth/width or increased number of input tokens -- consistently have lower FID. In addition to possessing good scalability properties, our largest DiT-XL/2 models outperform all prior diffusion models on the class-conditional ImageNet 512x512 and 256x256 benchmarks, achieving a state-of-the-art FID of 2.27 on the latter.

OpenAI Offers a Peek Inside the Guts of ChatGPT

ChatGPT developer OpenAI’s approach to building artificial intelligence came under fire this week from former employees who accuse the company of taking unnecessary risks with technology that could become harmful.

Today, OpenAI released a new research paper apparently aimed at showing it is serious about tackling AI risk by making its models more explainable. In the paper , researchers from the company lay out a way to peer inside the AI model that powers ChatGPT. They devise a method of identifying how the model stores certain concepts—including those that might cause an AI system to misbehave.

Although the research makes OpenAI’s work on keeping AI in check more visible, it also highlights recent turmoil at the company. The new research was performed by the recently disbanded “superalignment” team at OpenAI that was dedicated to studying the technology’s long-term risks.

The former group’s coleads, Ilya Sutskever and Jan Leike—both of whom have left OpenAI —are named as coauthors. Sutskever, a cofounder of OpenAI and formerly chief scientist, was among the board members who voted to fire CEO Sam Altman last November, triggering a chaotic few days that culminated in Altman’s return as leader.

ChatGPT is powered by a family of so-called large language models called GPT, based on an approach to machine learning known as artificial neural networks. These mathematical networks have shown great power to learn useful tasks by analyzing example data, but their workings cannot be easily scrutinized as conventional computer programs can. The complex interplay between the layers of “neurons” within an artificial neural network makes reverse engineering why a system like ChatGPT came up with a particular response hugely challenging.

“Unlike with most human creations, we don’t really understand the inner workings of neural networks,” the researchers behind the work wrote in an accompanying blog post . Some prominent AI researchers believe that the most powerful AI models, including ChatGPT, could perhaps be used to design chemical or biological weapons and coordinate cyberattacks. A longer-term concern is that AI models may choose to hide information or act in harmful ways in order to achieve their goals.

OpenAI’s new paper outlines a technique that lessens the mystery a little, by identifying patterns that represent specific concepts inside a machine learning system with help from an additional machine learning model. The key innovation is in refining the network used to peer inside the system of interest by identifying concepts, to make it more efficient.

OpenAI proved out the approach by identifying patterns that represent concepts inside GPT-4, one of its largest AI models. The company released code related to the interpretability work, as well as a visualization tool that can be used to see how words in different sentences activate concepts, including profanity and erotic content, in GPT-4 and another model. Knowing how a model represents certain concepts could be a step toward being able to dial down those associated with unwanted behavior, to keep an AI system on the rails. It could also make it possible to tune an AI system to favor certain topics or ideas.

Even though LLMs defy easy interrogation, a growing body of research suggests they can be poked and prodded in ways that reveal useful information. Anthropic, an OpenAI competitor backed by Amazon and Google, published similar work on AI interpretability last month. To demonstrate how the behavior of AI systems might be tuned, the company's researchers created a chatbot obsessed with San Francisco's Golden Gate Bridge . And simply asking an LLM to explain its reasoning can sometimes yield insights .

“It’s exciting progress,” says David Bau , a professor at Northeastern University who works on AI explainability, of the new OpenAI research. “As a field, we need to be learning how to understand and scrutinize these large models much better.”

Bau says the OpenAI team’s main innovation is in showing a more efficient way to configure a small neural network that can be used to understand the components of a larger one. But he also notes that the technique needs to be refined to make it more reliable. “There’s still a lot of work ahead in using these methods to create fully understandable explanations,” Bau says.

Bau is part of a US government-funded effort called the National Deep Inference Fabric , which will make cloud computing resources available to academic researchers so that they too can probe especially powerful AI models. “We need to figure out how we can enable scientists to do this work even if they are not working at these large companies,” he says.

OpenAI’s researchers acknowledge in their paper that further work needs to be done to improve their method, but also say they hope it will lead to practical ways to control AI models. “We hope that one day, interpretability can provide us with new ways to reason about model safety and robustness, and significantly increase our trust in powerful AI models by giving strong assurances about their behavior,” they write.

MLA General Format 

Welcome to the Purdue OWL

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

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

MLA Style specifies guidelines for formatting manuscripts and citing research in writing. MLA Style also provides writers with a system for referencing their sources through parenthetical citation in their essays and Works Cited pages. 

Writers who properly use MLA also build their credibility by demonstrating accountability to their source material. Most importantly, the use of MLA style can protect writers from accusations of plagiarism, which is the purposeful or accidental uncredited use of source material produced by other writers. 

If you are asked to use MLA format, be sure to consult the  MLA Handbook  (9th edition). Publishing scholars and graduate students should also consult the  MLA Style Manual and Guide to Scholarly Publishing  (3rd edition). The  MLA Handbook  is available in most writing centers and reference libraries. It is also widely available in bookstores, libraries, and at the MLA web site. See the Additional Resources section of this page for a list of helpful books and sites about using MLA Style.

Paper Format

The preparation of papers and manuscripts in MLA Style is covered in part four of the  MLA Style Manual . Below are some basic guidelines for formatting a paper in  MLA Style :

General Guidelines

• Type your paper on a computer and print it out on standard, white 8.5 x 11-inch paper.
• Double-space the text of your paper and use a legible font (e.g. Times New Roman). Whatever font you choose, MLA recommends that the regular and italics type styles contrast enough that they are each distinct from one another. The font size should be 12 pt.
• Leave only one space after periods or other punctuation marks (unless otherwise prompted by your instructor).
• Set the margins of your document to 1 inch on all sides.
• Indent the first line of each paragraph one half-inch from the left margin. MLA recommends that you use the “Tab” key as opposed to pushing the space bar five times.
• Create a header that numbers all pages consecutively in the upper right-hand corner, one-half inch from the top and flush with the right margin. (Note: Your instructor may ask that you omit the number on your first page. Always follow your instructor's guidelines.)
• Use italics throughout your essay to indicate the titles of longer works and, only when absolutely necessary, provide emphasis.
• If you have any endnotes, include them on a separate page before your Works Cited page. Entitle the section Notes (centered, unformatted).

Formatting the First Page of Your Paper

• Do not make a title page for your paper unless specifically requested or the paper is assigned as a group project. In the case of a group project, list all names of the contributors, giving each name its own line in the header, followed by the remaining MLA header requirements as described below. Format the remainder of the page as requested by the instructor.
• In the upper left-hand corner of the first page, list your name, your instructor's name, the course, and the date. Again, be sure to use double-spaced text.
• Double space again and center the title. Do not underline, italicize, or place your title in quotation marks. Write the title in Title Case (standard capitalization), not in all capital letters.
• Use quotation marks and/or italics when referring to other works in your title, just as you would in your text. For example:  Fear and Loathing in Las Vegas  as Morality Play; Human Weariness in "After Apple Picking"
• Double space between the title and the first line of the text.
• Create a header in the upper right-hand corner that includes your last name, followed by a space with a page number. Number all pages consecutively with Arabic numerals (1, 2, 3, 4, etc.), one-half inch from the top and flush with the right margin. (Note: Your instructor or other readers may ask that you omit the last name/page number header on your first page. Always follow instructor guidelines.)

Here is a sample of the first page of a paper in MLA style:

The First Page of an MLA Paper

Section Headings

Writers sometimes use section headings to improve a document’s readability. These sections may include individual chapters or other named parts of a book or essay.

MLA recommends that when dividing an essay into sections you number those sections with an Arabic number and a period followed by a space and the section name.

MLA does not have a prescribed system of headings for books (for more information on headings, please see page 146 in the MLA Style Manual and Guide to Scholarly Publishing , 3rd edition). If you are only using one level of headings, meaning that all of the sections are distinct and parallel and have no additional sections that fit within them, MLA recommends that these sections resemble one another grammatically. For instance, if your headings are typically short phrases, make all of the headings short phrases (and not, for example, full sentences). Otherwise, the formatting is up to you. It should, however, be consistent throughout the document.

If you employ multiple levels of headings (some of your sections have sections within sections), you may want to provide a key of your chosen level headings and their formatting to your instructor or editor.

Sample Section Headings

The following sample headings are meant to be used only as a reference. You may employ whatever system of formatting that works best for you so long as it remains consistent throughout the document.

Formatted, unnumbered:

Level 1 Heading: bold, flush left

Level 2 Heading: italics, flush left

Level 3 Heading: centered, bold

Level 4 Heading: centered, italics

Level 5 Heading: underlined, flush left
