If you’re citing a research article or paper in APA style, you’ll need to use a specific citation format that varies depending on the source. Assess whether your source is an article or report published in an academic journal or book, or whether it is an unpublished research paper, such as a print-only thesis or dissertation. Either way, your in-text citations will need to include information about the author (if available) and the date when your source was published or written.

Sample Citations

Writing an In-Text Citation

• For example, you may write, “Gardener (2008) notes, ‘There are several factors to consider about lobsters’ (p. 199).”

• For example, you may write, “‘There are several factors to consider about lobsters’ (Gardner, 2008, p. 199).” Or, “The paper claims, ‘The fallen angel trope is common in religious and non-religious texts’ (Meek & Hill, 2015, p.13-14).”
• For articles with 3-5 authors, write out the names of all the authors the first time you cite the source. For example: (Hammett, Wooster, Smith, & Charles, 1928). In subsequent citations, write only the first author’s name, followed by et al.: (Hammett et al., 1928).
• If there are 6 or more authors for the paper, include the last name of the first author listed and then write "et al." to indicate that there are more than 5 authors.
• For example, you may write, "'This is a quote' (Minaj et al., 1997, p. 45)."

• For example, you may write, “‘The risk of cervical cancer in women is rising’ (American Cancer Society, 2012, p. 2).”

• For example, you may write, “‘Shakespeare may have been a woman’ (“Radical English Literature,” 2004, p. 45).” Or, “The paper notes, ‘There is a boom in Virgin Mary imagery’ (“Art History in Italy,” 2011, p. 32).”

• For example, you may write, “‘There are several factors to consider about lobsters’ (Gardner, 2008, p. 199).” Or, “The paper claims, ‘The fallen angel trope is common in religious and non-religious texts’ (“Iconography in Italian Frescos,” 2015, p.13-14).”

• For example, you may write, “‘There are several factors to consider about lobsters’ (Gardner, 2008, p. 199).” Or, “The paper claims, ‘The fallen angel trope is common in religious and non-religious texts’ (“Iconography in Italian Frescos,” 2015, p.145-146).”

• For example, you may write, “‘The effects of food deprivation are long-term’ (Mett, 2005, para. 18).”

Creating a Reference List Citation for a Published Source

• Material on websites is also considered “published,” even if it’s not peer-reviewed or associated with a formal publishing company.
• While academic dissertations or theses that are print-only are considered unpublished, these types of documents are considered published if they’re included in an online database (such as ProQuest) or incorporated into an institutional repository.

• For example, you may write, “Gardner, L. M.” Or, “Meek, P. Q., Kendrick, L. H., & Hill, R. W.”
• If there is no author, you can list the name of the organization that published the research paper. For example, you may write, “American Cancer Society” or “The Reading Room.”
• Formally published documents that don’t list an author or that have a corporate author are typically reports or white papers .

• For example, you may write, “Gardner, L. M. (2008).” Or, “American Cancer Society. (2015).”

• For example, you may write, “Gardner, L. M. (2008). Crustaceans: Research and data.” Or, “American Cancer Society. (2015). Cervical cancer rates in women ages 20-45.”

• For example, for a journal article, you may write, “Gardner, L. M. (2008). Crustaceans: Research and data. Modern Journal of Malacostracan Research, 25, 150-305.”
• For a book chapter, you could write: “Wooster, B. W. (1937). A comparative study of modern Dutch cow creamers. In T. E. Travers (Ed.), A Detailed History of Tea Serviceware (pp. 127-155). London: Wimble Press."

• For example, you may write, “Kotb, M. A., Kamal, A. M., Aldossary, N. M., & Bedewi, M. A. (2019). Effect of vitamin D replacement on depression in multiple sclerosis patients. Multiple Sclerosis and Related Disorders, 29, 111-117. Retrieved from PubMed, https://www.ncbi.nlm.nih.gov/pubmed/30708308.
• If you’re citing a paper or article that was published online but did not come from an academic journal or database, provide information about the author (if known), the date of publication (if available), and the website where you found the article. For example: “Hill, M. (n.d.). Egypt in the Ptolemaic Period. Retrieved from https://www.metmuseum.org/toah/hd/ptol/hd_ptol.htm”

Citing Unpublished Sources in Your Reference List

• Print-only dissertations or theses.
• Articles or book chapters that are in press or have been recently prepared or submitted for publication.
• Papers that have been rejected for publication or were never intended for publication (such as student research papers or unpublished conference papers).

• If the paper is currently being prepared for publication, include the author’s name, the year when the current draft was completed, and the title of the article in italics, followed by “Manuscript in preparation.” For example: Wooster, B. W. (1932). What the well-dressed man is wearing. Manuscript in preparation.
• If the paper has been submitted for publication, format the citation the same way as if it were in preparation, but instead follow the title with “Manuscript submitted for publication.” For example: Wooster, B. W. (1932). What the well-dressed man is wearing. Manuscript submitted for publication.
• If the paper has been accepted for publication but is not yet published, replace the date with “in press.” Do not italicize the paper title, but do include the title of the periodical or book in which it will be published and italicize that. For example: Wooster, B. W. (in press). What the well-dressed man is wearing. Milady’s Boudoir.

• If the paper was written for a conference but never published, your citation should look like this: Riker, W. T. (2019, March). Traditional methods for the preparation of spiny lobe-fish. Paper presented at the 325th Annual Intergalactic Culinary Conference, San Francisco, CA.
• For an unpublished paper written by a student for a class, include details about the institution where the paper was written. For example: Crusher, B. H. (2019). A typology of Cardassian skin diseases. Unpublished manuscript, Department of External Medicine, Starfleet Academy, San Francisco, CA.

• For example, you may write, “Pendlebottom, R. H. (2011). Iconography in Italian Frescos (Unpublished doctoral dissertation). New York University, New York, United States.”

About This Article

To cite a research paper in-text in APA, name the author in the text to introduce the quote and put the publication date for the text in parentheses. At the end of your quote, put the page number in parentheses. If you don’t mention the author in your prose, include them in the citation. Start the citation, which should come at the end of the quote, by listing the author’s last name, the year of publication, and the page number. Make sure to put all of this information in parentheses. If there’s no author, use the name of the organization that published the paper or the first few words from the title.

What is APA Style?

APA style was created by social and behavioral scientists to standardize scientific writing. APA style is most often used in:

• psychology,
• social sciences (sociology, business), and

If you're taking courses in any of these areas, be prepared to use APA style.

For in-depth guidance on using this citation style, refer to Publication Manual of the American Psychological Association , 7th ed. We have several copies available at the MJC Library at the call number  BF 76.7 .P83 2020 .

APA Style, 7th ed.

In October 2019, the American Psychological Association made radical changes its style, especially with regard to the format and citation rules for students writing academic papers. Use this guide to learn how to format and cite your papers using APA Style, 7th edition.

You can start by viewing the  video tutorial .

For help on all aspects of formatting your paper in APA Style, see   The Essentials  page on the APA Style website.

• sans serif fonts such as 11-point Calibri, 11-point Arial, or 10-point Lucida Sans Unicode, or
• serif fonts such as 12-point Times New Roman, 11-point Georgia, or normal (10-point) Computer Modern (the default font for LaTeX)
• There are exceptions for the  title page ,  tables ,  figures ,  footnotes , and  displayed equations .
• Margins :  Use 1-in. margins on every side of the page.
• Align the text of an APA Style  paper to the left margin . Leave the right margin uneven, or “ragged.”
• Do not use full justification for student papers.
• Do not insert hyphens (manual breaks) in words at the end of line. However, it is acceptable if your word-processing program automatically inserts breaks in long hyperlinks (such as in a DOI or URL in a reference list entry).
• Indent the first line of each paragraph of text 0.5 in . from the left margin. Use the tab key or the automatic paragraph-formatting function of your word-processing program to achieve the indentation (the default setting is likely already 0.5 in.). Do not use the space bar to create indentation. 
• There are exceptions for the  title page ,  section labels ,  abstract ,  block quotations ,  headings ,  tables and figures ,  reference list , and  appendices .

Paper Elements

Student papers generally include, at a minimum: 

• Title Page (2.3)
• Text (2.11)
• References  (2.12)

Student papers may include additional elements such as tables and figures depending on the assignment. So, please check with your teacher!

Student papers generally  DO NOT  include the following unless your teacher specifically requests it:

• Running head
• Author note

For complete information on the  order of pages , see the APA Style website.

Number your pages consecutively starting with page 1. Each section begins on a new page. Put the pages in the following order:

• Page 1: Title page
• Page 2: Abstract (if your teacher requires an abstract)
• Page 3: Text 
• References begin on a new page after the last page of text
• Footnotes begin on a new page after the references (if your teacher requires footnotes)
• Tables begin each on a new page after the footnotes (if your teacher requires tables) 
• Figures begin on a new page after the tables (if your teacher requires figures)
• Appendices begin on a new page after the tables and/or figures (if your teacher requires appendices)

Sample Papers With Built-In Instructions

To see what your paper should look like, check out these sample papers with built-in instructions.

APA Style uses five (5) levels of headings to help you organize your paper and allow your audience to identify its key points easily. Levels of headings establish the hierarchy of your sections just like you did in your paper outline.

APA tells us to use "only the number of headings necessary to differentiate distinct section in your paper." Therefore, the number of heading levels you create depends on the length and complexity of your paper.

See the chart below for instructions on formatting your headings:

Use Word to Format Your Paper:

Use Google Docs to Format Your Paper:

Placement:  The reference list  appears at the end of the paper, on its own page(s). If your research paper ends on page 8, your References begin on page 9.

Heading:  Place the section label References  in bold at the top of the page, centered.

Arrangement:  Alphabetize entries by author's last name. If source has no named author, alphabetize by the title, ignoring A, An, or The. (9.44-9.48)

Spacing:  Like the rest of the APA paper, the reference list is double-spaced throughout. Be sure NOT to add extra spaces between citations.

Indentation:  To make citations easier to scan, add a  hanging indent  of 0.5 in. to any citation that runs more than one line. Use the paragraph-formatting function of your word processing program to create your hanging indent.  

See Sample References Page (from APA Sample Student Paper):

Elements of Reference List Entries: (Chapter 9)

References generally have four elements, each of which has a corresponding question for you to answer:

• Author:   Who is responsible for this work? (9.7-9.12)
• Date:   When was this work published? (9.13-9.17)
• Title:   What is this work called? (9.18-9.22)
• Source:   Where can I retrieve this work? (9.23-9.37)

By using these four elements and answering these four questions, you should be able to create a citation for any type of source.

For complete information on all of these elements, checkout the APA Style website.

This infographic shows the first page of a journal article. The locations of the reference elements are highlighted with different colors and callouts, and the same colors are used in the reference list entry to show how the entry corresponds to the source.

To create your references, you'll simple look for these elements in your source and put them together in your reference list entry.

Sometimes you won't be able to find all the elements required for your reference. In that case, see the  instructions in Table 9.1 of the APA style manual in section 9.4 or the APA Style website below:

• Direct Quotation of Material Without Page Numbers

The DOI or URL is the final component of a reference list entry. Because so much scholarship is available and/or retrieved online, most reference list entries end with either a DOI or a URL.

• A  DOI  is a unique alphanumeric string that identifies content and provides a persistent link to its location on the internet. DOIs can be found in database records and the reference lists of published works.
• A  URL  specifies the location of digital information on the internet and can be found in the address bar of your internet browser. URLs in references should link directly to the cited work when possible.

When to Include DOIs and URLs:

• Include a DOI for all works that have a DOI, regardless of whether you used the online version or the print version.
• If an online work has both a DOI and a URL, include only the DOI.
• For works without DOIs from websites (not including academic research databases), provide a URL in the reference (as long as the URL will work for readers).
• For works without DOIs from most academic research databases, do not include a URL or database information in the reference because these works are widely available. The reference should be the same as the reference for a print version of the work.
• For works from databases that publish original, proprietary material available only in that database (such as the UpToDate database) or for works of limited circulation in databases (such as monographs in the ERIC database), include the name of the database or archive and the URL of the work. If the URL requires a login or is session-specific (meaning it will not resolve for readers), provide the URL of the database or archive home page or login page instead of the URL for the work. (See APA Section 9.30 for more information). 
• If the URL is no longer working or no longer provides readers access to the content you intend to cite, try to find an archived version using the Internet Archive , then use the archived URL. If there is no archived URL, do not use that resource.

Format of DOIs and URLs:

Your DOI should look like this: 

https://doi.org/10.1037/a0040251

Follow these guidelines from the APA Style website.

APA Style uses the  author–date citation system , in which a brief in-text citation points your reader to the full reference list entry at the end of your paper. The in-text citation appears within the body of the paper and briefly identifies the cited work by its author and date of publication. This method enables your reader to locate the corresponding entry in the alphabetical reference list at the end of your paper.

Each work you cite  must  appear in the reference list, and each work in the reference list must be cited in the text (or in a table, figure, footnote, or appendix) except for the following (See APA, 8.4):

• Personal communications (8.9)
• General mentions of entire websites, whole periodicals (8.22), and common software and apps (10.10) in the text do not require a citation or reference list entry.
• The source of an epigraph does not usually appear in the reference list (8.35)
• Quotations from your research participants do not need citations or reference list entries (8.36)
• References included in a statistical meta-analysis, which are marked with an asterisk in the reference list, may be cited in the text (or not) at the author’s discretion. This exception is relevant only to authors who are conducting a meta-analysis (9.52).

Formatting Your In-Text Citations

Parenthetical and Narrative Citations: ( See APA Section  8.11)

In APA style you use the author-date citation system for citing references within your paper. You incorporate these references using either a  parenthetical   or a  narrative  style.

Parenthetical Citations

• In parenthetical citations, the author name and publication date appear in parentheses, separated by a comma. (Jones, 2018)
• A parenthetical citation can appear within or at the end of a sentence.
• When the parenthetical citation is at the end of the sentence, put the period or other end punctuation after the closing parenthesis.
• If there is no author, use the first few words of the reference list entry, usually the "Title" of the source: ("Autism," 2008) See APA 8.14
• When quoting, always provide the author, year, and specific page citation or paragraph number for nonpaginated materials in the text (Santa Barbara, 2010, p. 243).  See APA 8.13
• For most citations, the parenthetical reference is placed BEFORE the punctuation: Magnesium can be effective in treating PMS (Haggerty, 2012).

Narrative Citations 

In narrative citations, the author name or title of your source appears within your text and the publication date appears in parentheses immediately after the author name. 

• Santa Barbara (2010) noted a decline in the approval of disciplinary spanking of 26 percentage points from 1968 to 1994.

Fundamentals of APA

American Psychological Association (APA) style includes  parenthetical in-text citations  and a  reference list . 

APA uses  parenthetical citations  as its form of in-text citation. Provide a parenthetical citation  before the period  directly following the information you are citing. These citations should correspond to a more detailed citation in the reference list but only need to specify a page number if directly quoting or borrowing from the source material. The essential elements for this in-text citation are the author's last name and the date for the specific publications. The last name may be omitted if the sentence states or makes clear the source material.

APA uses a  reference list ,  an alphabetized list of sources following the end of the book or paper,  for its complete list of sources referenced. This list should be titled "References" in bold and alphabetized by the first item in the citation, which, in most cases, is the author's last name. Each reference from this list must be cited in your paper and vice versa.

Basic Format

Author Last Name, Author First Initial. (Year of publication). Title . Publisher Name.

Print Articles

Author Last Name, Author First Initial, & Author Last Name, Author First Initial. (Year). Article Title. Periodical Title , volume number(issue number), pages.

Electronic Articles

Author Last Name, Author First Initial. (Year). Article Title. Periodical Title , volume number(issue number), pages. doi or static url.

Physical Images/Artwork

Artist Last Name, Artist First Initial. (Year). Artwork Title [medium]. Host Institution Name, City, State, Country. URL of institution.

Electronic Images/Artwork

Artist Last Name, Artist First Initial. (Year). Image Title [medium]. Source Title. URL of image.

In-text Citation Examples

Standard case :

"Lorem   ipsum  dolor sit  amet ,  consectetur   adipiscing   elit" (Last name, 2000, p.10).

If the author is not available , the title of the source may be used:

Lorem   ipsum  dolor sit  amet ,  consectetur   adipiscing   elit ("Source title", 2000, pp.10-11).

If multiple authors cited have the same last name , use the author's first initial along with their last name:

"Lorem   ipsum  dolor sit  amet ,  consectetur   adipiscing   elit" (E. Bronte, 1847, p.10).

Lorem   ipsum  dolor sit  amet ,  consectetur   adipiscing   elit (C. Bronte, 1847, p.10).

Being responsible while researching

When you’re writing a research paper or creating a research project, you will probably use another individual’s work to help develop your own assignment. A good researcher or scholar uses another individual’s work in a responsible way. This involves indicating that the work of other individuals is included in your project (i.e., citing), which is one way to prevent plagiarism.

Plagiarism? What is it?

The word plagiarism is derived from the Latin word, plagiare , which means “to kidnap.” The term has evolved over the years to now mean the act of taking another individual’s work and using it as your own, without acknowledging the original author (American Psychological Association, 2020 p. 21). Plagiarism can be illegal and there can be serious ramifications for plagiarizing someone else’s work. Thankfully, plagiarism can be prevented. One way it can be prevented is by including citations and references in your research project. Want to make them quickly and easily? Try the Citation Machine citation generator, which is found on our homepage.

All about citations & references

Citations and references should be included anytime you use another individual’s work in your own assignment. When including a quote, paraphrased information, images, or any other piece of information from another’s work, you need to show where you found it by including a citation and a reference. This guide explains how to make them.

APA style citations are added in the body of a research paper or project and references are added to the last page.

Citations , which are called in-text citations, are included when you’re adding information from another individual’s work into your own project. When you add text word-for-word from another source into your project, or take information from another source and place it in your own words and writing style (known as paraphrasing), you create an in-text citation. These citations are short in length and are placed in the main part of your project, directly after the borrowed information.

References are found at the end of your research project, usually on the last page. Included on this reference list page is the full information for any in-text citations found in the body of the project. These references are listed in alphabetical order by the author's last name.

An APA in-text citation includes only three items: the last name(s) of the author(s), the year the source was published, and sometimes the page or location of the information. References include more information such as the name of the author(s), the year the source was published, the full title of the source, and the URL or page range.

Why is it important to include citations & references

Including APA citations and references in your research projects is a very important component of the research process. When you include citations, you’re being a responsible researcher. You’re showing readers that you were able to find valuable, high-quality information from other sources, place them into your project where appropriate, all while acknowledging the original authors and their work.

Common ways students and scholars accidentally plagiarize

Believe it or not, there are instances when you could attempt to include in-text and full references in the appropriate places, but still accidentally plagiarize. Here are some common mistakes to be aware of:

Mistake #1 - Misquoting sources: If you plan to use a direct quote, make sure you copy it exactly as is. Sure, you can use part of the full quote or sentence, but if you decide to put quotation marks around any words, those words should match exactly what was found in the original source. Here’s a line from The Little Prince , by Antoine de Saint-Exupéry:

“Grown-ups never understand anything by themselves, and it is tiresome for children to be always and forever explaining things to them.”

Here’s an acceptable option:

“Grown-ups never understand anything by themselves,” stated de Saint-Exupéry (1943, p. 3).

Here’s a misquote:

“Grown-ups barely ever understand anything by themselves,” stated de Saint-Exupéry (1943, p. 3).

Notice the slight change in the words. The incorrect phrasing is an instance of accidental plagiarism.

Mistake #2 - Problems with paraphrasing: When we paraphrase, we restate information using our own words and writing style. It’s not acceptable to substitute words from the original source with synonyms.

Let’s use the same sentence from The Little Prince .

A correct paraphrase could be:

de Saint-Exupéry (1943) shares various ways adults frustrate children. One of the biggest being that kids have to explain everything. It’s too bad adults are unable to comprehend anything on their own (p. 3).

An incorrect paraphrase would be:

de Saint-Exupéry (1943) shares that adults never understand anything by themselves, and it is exhausting for kids to be always and forever clarifying things to them (p.3).

Notice how close the incorrect paraphrase is from the original. This is an instance of accidental plagiarism.

Make sure you quote and paraphrase properly in order to prevent accidental plagiarism.

If you’re having a difficult time paraphrasing properly, it is acceptable to paraphrase part of the text AND use a direct quote. Here’s an example:

de Saint-Exupery (1943) shares various ways adults frustrate children. One of the biggest being that kids have to explain everything, and “it is tiresome for children to be always and forever explaining things to them” (p. 3).

Information About APA

Who created it.

The American Psychological Association is an organization created for individuals in the psychology field. With close to 121,000 members, they provide educational opportunities, funding, guidance, and research information for everything psychology-related. They also have numerous high-quality databases, peer-reviewed journals, and books that revolve around mental health.

The American Psychological Association is also credited with creating their own specific citation and reference style. Today, this format is used by individuals not only in the psychology field, but many other subject areas as well. Education, economics, business, and social sciences also use APA style quite frequently. Click here for more information . This guide covers general information about the style, but is not affiliated with the American Psychological Association.

Why was this style created?

This format was first developed in 1929 to form a standardized way for researchers in science fields to document their sources. Prior to the inception of these standards and guidelines, individuals were recognizing the work of other authors by including bits and pieces of information in random order. There wasn’t a set way to format citations and references. You can probably imagine how difficult it was to understand the sources that were used for research projects!

Having a standard format for citing sources allows readers to glance at a citation or APA reference and easily locate the title, author, year published, and other critical pieces of information needed to understand a source.

The evolution of this style

The guide below is based on APA style 7th edition, which was released in 2020. In previous versions of APA format, researchers and scholars were required to include the publisher location for books and the date that an electronic resource was accessed. Both are no longer required to be included.

Details on the differences between the 6th and 7th editions is addressed later in this guide.

Citations & References

The appearance of citations & references.

The format for references varies, but most use this general format:

%%Author’s Last name, First initial. (Date published). Title . URL

Researchers and scholars must look up the proper format for the source that they’re attempting to cite. Books have a certain format, websites have a different format, periodicals have a different format, and so on. Scroll down to find the proper format for the source you’re citing or referencing.

• Journal articles

In-text citations

An APA in-text citation is included in research projects in three instances: When using a direct quote, paraphrasing information, or simply referring to a piece of information from another source.

Quite often, researchers and scholars use a small amount of text, word for word, from another source and include it in their own research projects. This is done for many reasons. Sometimes, another author’s words are so eloquently written that there isn’t a better way to rephrase it yourself. Other times, the author’s words can help prove a point or establish an understanding for something in your research project. When using another author’s exact words in your research project, include an APA in-text citation directly following it.

In addition to using the exact words from another source and placing them into your project, these citations are also added anytime you paraphrase information. Paraphrasing is when you take information from another source and rephrase it, in your own words.

When simply referring to another piece of information from another source, also include a citation directly following it.

Citations in the text are found near a direct quote, paraphrased information, or next to a mention of another source. To see examples of some narrative/ parenthetical citations in action, look at the image above, under “All About Citations & References.”

Note: *Only include the page or paragraph number when using a direct quote or paraphrase. Page numbers have a p. before the number, pp. before the page range, and para. before the paragraph number. This information is included to help the reader locate the exact portion of text themselves. It is unnecessary to include this information when you’re simply referring to another source.

Examples of APA in-text citations:

“Well, you’re about to enter the land of the free and the brave. And I don’t know how you got that stamp on your passport. The priest must know someone” (Tóibín, 2009, p. 52).

Student teachers who use technology in their lessons tend to continue using technology tools throughout their teaching careers (Kent & Giles, 2017, p. 12).

If including the author’s name in the sentence, place the year in the parentheses directly next to his or her name. Add the page number at the end, unless it’s a source without any pages or paragraph numbers (See Section 8.10 of the Publication manual for more details).

In-text citation APA example:

According to a study done by Kent and Giles (2017), student teachers who use technology in their lessons tend to continue using technology tools throughout their teaching careers.

The full references, or citations, for these sources can be found on the last part of a research project, titled the “References.”

Here’s how to create in-text citations for specific amounts of authors:

APA citation with no author

When the source lacks an author’s name, place the title, year, and page number (if available) in the text. The title should be in italics if it sits alone (such as a movie, brochure, or report). If the source is part of a whole (as many web pages and articles are), place the title in quotation marks without italics (See Section 8.14 of the Publication manual ).

Structure of an APA format citation in the text narratively, with the author's name missing:

Title of Source (Year) or “Title of Source” (Year)

Structure of an APA style format citation, in parentheses at the end of the sentence, with the author’s name missing: (Title of Source, Year) or (“Title of Source,” Year)

Structure for one author

In the text, narratively: Last name of Author (Year)...(page number).

In parentheses, at the end of the sentence: (Last name of Author, Year, page number).

Structure for two authors

Place the authors in the order they appear on the source. Only use the ampersand in the parenthetical citations (see Section 8.17 of the Publication manual ). Use ‘and’ to separate the author names if they’re in the text of the sentence.

In the text, narratively: Last name of Author 1 and Last name of Author 2 (Year)....(page number).

In parentheses, at the end of the sentence: (Last name of Author 1 & Last name of Author 2, Year, page number).

Structure for three or more authors

Only include the first listed author’s name in the first and any subsequent citations. Follow it with et al.

(Last name Author 1 et al., Year, page number)

(Agbayani et al., 2020, p. 99)

Last name of Author 1 et al. (Year)...(page).

Agbayani et al. (2020)...(p. 99)

One author, multiple works, same year

What do you do when you want to cite multiple works by an author, and the sources all written in the same year?

Include the letters ‘a’ ‘b’ ‘c’ and so on after the year in the citation.

(Jackson, 2013a)

Jackson (2013a)

Writers can even lump dates together.

Example: Jackson often studied mammals while in Africa (2013a, 2013b).

On the APA reference page, include the same letters in the full references.

Groups and organizations

Write out the full name of the group or organization in the first citation and place the abbreviation next to it in brackets. If the group or organization is cited again, only include the abbreviation. If it doesn’t have an abbreviation associated with it, write out the entire organization’s name each and every time (see Section 8.21 of the Publication manual ).

First APA citation for an organization with an abbreviation: (World Health Organization [WHO], Year)

World Health Organization (WHO, Year)

Notice in the example directly above, the name of the organization is written out in full in the text of the sentence, and the abbreviation is placed in parentheses next to it.

Subsequent APA citations in the text for an organization with an abbreviation: (WHO, Year) OR WHO (Year)

All citations in the text for an organization without an abbreviation: (Citation Machine, Year) or Citation Machine (Year)

One in-text citation, multiple works

Sometimes you’ll need to cite more than one work within an in-text citation. Follow the same format (author, year) format but place semicolons between works (p. 263).

(Obama, 2016; Monroe et al., 1820; Hoover & Coolidge, 1928)

Reference list citation components

References display the full information for all the citations found in the body of a research project.

Some things to keep in mind when it comes to the references:

• All references sit together on their own page, which is usually the last page(s) of a paper.
• Title the page ‘References’
• Place ‘References’ in the center of the page and bold it. Keep the title in the same font and size as the references. Do not italicize, underline, place the title in quotation marks, or increase the font size.
• The entire page is double spaced.
• All references are listed in alphabetical order by the first word in the reference, which is usually the author’s last name. If the source lacks an author, alphabetize the source by the title (ignore A, An, or The)
• All references have a hanging indent, meaning that the second line of text is indented in half an inch. See examples throughout this guide.
• Remember, each and every citation in the text of the paper MUST have a full reference displayed in the reference list. The citations in the text provide the reader with a quick glimpse about the sources used, but the references in the reference list provide the reader with all the information needed to seek out the source themselves.

Learn more about each component of the reference citation and how to format it in the sections that follow. See an APA sample paper reference list at the end of this entire section.

Author’s names

The names of authors are written in reverse order. Include the initials for the first and middle names. End this information with a period (see Section 9.8 of the Publication manual ).

Format: Last name, F. M.

• Angelou, M.
• Doyle, A. C.

Two or more authors

When two or more authors work together on a source, write them in the order in which they appear on the source. You can name up to 20 authors in the reference. For sources with 2 to 20 authors, place an ampersand (&) before the final author. Use this format:

Last name, F. M., & Last name, F. M.

Last name, F. M., Last name, F. M., Last name, F. M., Last name, F. M., & Last name, F. M.

Kent, A. G., Giles, R. M., Thorpe, A., Lukes, R., Bever, D. J., & He, Y.

If there are 21 or more authors listed on a source, only include the first 19 authors, add three ellipses, and then add the last author’s name.

Roberts, A., Johnson, M. C., Klein, J., Cheng, E. V., Sherman, A., Levin, K. K. , ...Lopez, G. S.

If you plan on using a free APA citation tool, like the one at CitationMachine.com, the names of the authors will format properly for you.

###No authors

If the source lacks an author, place the title in the first position in the reference (Section 9.12 of the Publication manual ). When the source’s title begins with a number (Such as 101 Dalmatians ), place the reference alphabetically as if the number was spelled out. 101 Dalmatians would be placed in the spot where ‘One hundred’ would go, but keep the numbers in their place.

Additionally, if the title begins with the words ‘A’, ‘An,’ or ‘The,’ ignore these words and place the title alphabetically according to the next word.

See the “Titles” section below for more information on formatting the title of sources.

###Corporate/Organization authors

On an APA reference page, corporate authors are always written out in full. In the text of your paper, you may have some abbreviations (such as UN for United Nations), but in the full references, always include the full names of the corporation or organization (following Section 9.11 of the official Publication manual ).

%%United Nations. (2019). Libya: $202 million needed to bring life-saving aid to half a million people hit by humanitarian crisis. https://news.un.org/en/story/2019/02/1031981

Publication date & retrieval date

Directly after the author’s name is the date the source was published. Include the full date for newspapers and magazine articles, and only the year for journals and all other sources. If no date is found on the source, include the initials, n.d. for “no date.”

%% Narducci, M. (2017, May 19). City renames part of 11th Street Ed Snider Way to honor Flyers founder. The Philadelphia Inquirer . http://www.philly.com/

If using our APA Citation Machine, our citation generator will add the correct format for you automatically.

Giving a retrieval date is not needed unless the online content is likely to be frequently updated and changed (e.g., encyclopedia article, dictionary entry, Twitter profile, etc.).

%%Citation Machine [@CiteMachine]. (n.d.). Tweets [Twitter profile]. Twitter. Retrieved October 10, 2019, from https://twitter.com/CiteMachine

When writing out titles for books, articles, chapters, or other non-periodical sources, only capitalize the first word of the title and the first word of the subtitle. Names of people, places, organizations, and other proper nouns also have the first letter capitalized. For books and reports, italicize the title in the APA citation.

Strange case of Dr. Jekyll and Mr. Hyde.

Roots: The saga of an American family.

For articles and chapters in APA referencing, do not italicize the title.

Wake up the nation: Public libraries, policy making, and political discourse.

For newspapers, magazines, journals, newsletters, and other periodicals, capitalize the first letter in each word and italicize the title.

The Seattle Times.

A common question is whether to underline your title or place it in italics or quotation marks in the reference list. Here’s a good general rule: When a source sits alone and is not part of a larger whole, place the title in italics. If the source does not sit alone and is part of a larger whole, do not place it in italics.

Books, movies, journals, and television shows are placed in italics since they stand alone. Songs on an album, episodes of television shows, chapters in books, and articles in journals are not placed in italics since they are smaller pieces of larger wholes.

The Citation Machine citation generator will format the title in your citations automatically.

Additional information about the title

If you feel it would be helpful to include additional information about the source type, include a descriptive noun or two in brackets immediately following the title. Capitalize the first letter.

%%Kennedy, K., & Molen, G. R. (Producers), & Spielberg, S. (Director). (1993). Jurassic Park [Film]. USA: Universal.

Besides [Film], other common notations include:

• [Audio podcast]
• [Letter to the editor]
• [Television series episode]
• [Facebook page]
• [Blog post]
• [Lecture notes]
• [PowerPoint presentation]
• [Video file]

If you are using Citation Machine citing tools, additional information about the title is automatically added for you.

Publisher information

For books and reports, include the publisher name but not the location (see Section 9.29 of the Publication manual ). Older editions of the style required the city, state and/or country, but this hasn't been the case since the 7th edition was released.

It is not necessary to include the entire name of the publisher. It is acceptable to use a brief, intelligible form. However, if Books or Press are part of the publisher’s names, keep these words in the reference. Other common terms, such as Inc., Co., Publishers, and others can be omitted.

For newspapers, journals, magazines, and other periodicals, include the volume and issue number after the title. The volume number is listed first, by itself, in italics. The issue number is in parentheses immediately after it, not italicized. There is no space after the closing parenthesis and before the volume number.

%%Giannoukos, G., Besas, G., Hictour, V., & Georgas, T. (2016). A study on the role of computers in adult education. Educational Research and Reviews , 11 (9), 907-923. https://doi.org/10.5897/ERR2016.2688

After including the publisher information, end this section with a period.

Perseus Books.

Electronic source information:

For online sources, the URL or DOI (Direct Object Identifier) are included at the end of an APA citation.

DOI numbers are often created by publishers for journal articles and other periodical sources. They were created in response to the problem of broken or outdated links and URLs. When a journal article is assigned a DOI number, it is static and will never change. Because of its permanent characteristic, DOIs are the preferred type of electronic information to include in APA citations. When a DOI number is not available, include the source’s URL (see Section 9.34 in the Publication manual ).

For DOIs, include the number in this format:

http://doi.org/xxxx

For URLs, type them in this format:

http:// or https://

Other information about electronic sources:

• If the URL is longer than a line, break it up before a punctuation mark.
• Do not place a period at the end of the citation/URL.
• It is unnecessary to include retrieval dates, unless the source changes often over time (like in a Wikipedia article).
• It is not necessary to include the names of databases

If using the Citation Machine APA citation website autocite features, the online publication information will be automatically replaced by the DOI. The Citation Machine APA template will properly cite your online sources for you.

Make sure you run your completed paper through the Citation Machine Plus smart proofreader, which scans for grammar, spelling, and plagiarism. Whether it’s an adjective , verb , or pronoun out-of-place, our technology helps edits your paper for you!

Annotated bibliographies:

An APA annotated bibliography is a full bibliography that includes a small note for each reference citation. Each note should be short (1-2 paragraphs) and contain a summary or your evaluation about each source. When creating your citations on CitationMachine.net, there is a field at the bottom of each form to add your own annotations.

Follow the publication manual guidelines on paper format and writing style. Let your instructor guide other details about your annotations. Still confused? Read our guide on annotated bibliographies .

These types of projects look different depending on the style you’re using. Use the link at the top of the page to access resources related to the Modern Language Association’s style. Here’s information related to Chicago citation style .

Page formatting

Need help with the design and formatting of your paper? Look no further! This section provides the ins and outs of properly displaying the information in your APA essay.

• Times New Roman, 12-point size.
• Calibri, Arial, or Georgia, 11-point size
• Lucida, Sans Unicode, or Computer Modern, 10-point size
• Indents = Every paragraph should start with an indent.
• Margins = 1 inch around the entire document
• Spacing = Double space everything!

Arrange your pages in this order:

• Page 1 - APA Title Page (see below for information on the title page)
• Page 2 - Abstract (If your professor requests one)
• Page 3 - First page of text
• References begin on their own page. Include the list of references on the page after the text.
• Tables and figures

Keep in mind that the order above is the recommendation for papers being submitted for peer review. If you’re writing an APA style paper for a class, your professor may be more lenient about the requirements. Also, if you’re submitting your paper for a specific journal, check the requirements on the journal’s website. Each journal has different rules and procedures.

Just a little nudge to remind you about the Citation Machine Plus smart proofreader. Whether it’s a conjunction or interjection out of place, a misspelled word, or an out of place citation, we’ll offer suggestions for improvement! Don’t forget to check out our APA citation maker while you’re at it!

Running heads

In older editions of APA, running heads were required for all papers. Since the 7th edition, that’s changed.

• Student paper: No running head
• Professional paper: Include a running head

The running head displays the title of the paper and the page number on all pages of the paper. This header is found on every page of a professional paper (not a student paper), even on the title page (sometimes called an APA cover page) and reference list (taken from Section 2.8 of the Publication manual ).

It's displayed all in capital letters at the top of the page. Across from the running head, along the right margin, is the page number.

• Use the header feature in your word processor. Both Google Docs and Word have these features available.
• Use one for the recommended fonts mentioned under "Page formatting."

Title pages

A title page, sometimes called an APA cover page, graces the cover of an essay or paper. An APA title page should follow rules from Section 2.3 of the official Publication manual and include:

• Page number, which is page 1
• Use title case and bold font
• The title should be under 12 words in length
• The title should be a direct explanation of the focus of the paper. Do not include any unnecessary descriptors such as “An Analysis of…” or “A Study of…”
• Exclude any labels such as Mr., Ms., Dr, PhD...
• Name of the school or institution
• Course number and/or class name
• Name of your instructor, including their preferred honorifics (e.g., PhD, Dr., etc.)
• Paper’s due date
• If this is a professional paper, also include a running head. If this is a student paper, do not include one.

Follow the directions for the running head and page number in the section above. Below the running head, a few lines beneath, and centered in the middle of the page, should be the title. The next line below is the author’s name(s), followed by the name of the school or institution, the class or course name, your instructor’s name, and the paper’s due date.

All components on this page should be written in the same font and size as the rest of your paper. Double space the title, names, name of school or institution, and all other information on the page (except for the running head and page number).

Example - Student Title Page APA:

Example - Professional Title Page APA:

If you’re submitting your paper to a journal for publication, check the journal’s website for exact requirements. Each journal is different and some may request a different type of APA format cover page.

An abstract briefly but thoroughly summarizes dissertation contents. It’s found in the beginning of a professional paper, right after the title page. Abstracts are meant to help readers determine whether to continue reading the entire document. With that in mind, try to craft the lead sentence to entice the reader to continue reading.

Here are a few tips:

• Be factual and keep your opinions out. An abstract should accurately reflect the paper or dissertation and should not involve information or commentary not in the thesis.
• Communicate your main thesis. What was the examined problem or hypothesis? A reader should know this from reading your abstract.
• Keep it brief. Stick to the main points and don’t add unnecessary words or facts. It should not exceed 250 words.
• Consider your paper’s purpose. It’s important to cater your abstract to your paper type and think about what information the target audience for that paper type would want. For example, an empirical article may mention methodology or participant description. A quantitative or qualitative meta-analysis would mention the different variables considered and how information was synthesized.
• Use verbs over noun equivalents, and active voice. Example: “There was research into…” becomes “We researched…”

Formatting guidelines:

• The abstract goes after the title page.
• It should have the same font (size and type) as the rest of the paper.
• It should stick to one page.
• Double-space all page text.
• Center and bold the word “Abstract” at the top of the paper.
• Don’t indent the first line of the abstract body. The body should also be in plain text.
• For the keywords, place it on the line after the abstract and indent the first line (but not subsequent lines). The word “Keywords:” is capitalized, italicized, and followed by a colon. The actual keywords are sentence case and in plan font.
• List each keyword one after the other, and separate them by a comma.
• After the last keyword, no ending punctuation is needed.

Tables & Figures

If your paper includes a lot of numerical information or data, you may want to consider placing it into a table or a figure, rather than typing it all out. A visual figure or simple, organized table filled with numerical data is often easier for readers to digest and comprehend than tons of paragraphs filled with numbers. Chapter 7 of the Publication manual outlines formatting for tables and figures. Let's cover the basics below.

If you’d like to include a table or figure in your paper, here are a few key pieces of information to keep in mind:

• At the end of the paper after the APA reference page
• In the text after it is first mentioned
• The table first mentioned in the text should be titled ‘Table 1.’ The next table mentioned in the text is ‘Table 2,’ and so on. For figures, it would be 'Figure 1,' 'Figure 2,' and so forth.

• Even though every table and figure is numbered, also create a title for each that describes the information it contains. Capitalize all important words in the title.
• For tables, do not use any vertical lines, only use horizontal to break up information and headings.
• Single spacing is acceptable to use in tables and figures. If you prefer double spacing your information, that is okay too.
• Do not include extra information or “fluff.” Keep it simple!
• Do not include the same exact information in the paper. Only include the complete information in one area—the table or the text.
• All tables and figures must be referenced in the text. It is unacceptable to throw a table or figure into the back of the paper without first providing a brief summary or explanation of its relevance.

Publication Manual 6th Edition vs 7th Edition

The 6th edition of the Publication Manual of the American Psychological Association was released in 2009. The current 7th edition came out in the fall of 2019 and was designed to be more student focused, provide more guidance on accessibility, and address changes that have developed over the last 10 years.

Below, we’ve listed what we feel are the most relevant changes related to APA format.

Journals and DOIs

DOI stands for “digital object identifier.” Many journal articles use and have a unique DOI that should be included in a full citation.

When including a DOI in a citation, format it as a URL. Do not label it “DOI.” Articles without DOIs from databases are treated as print works. For example:

6th edition:

%%Gänsicke, B. T., Schreiber, M. R., Toloza, O., Fusillo, N. P. G., Koester, D., & Manser, C. J. (2019). Accretion of a giant planet onto a white dwarf star. Nature, 576 (7785), 61–64. doi: 10.1038/s41586-019-1789-8

7th edition:

%%Gänsicke, B. T., Schreiber, M. R., Toloza, O., Fusillo, N. P. G., Koester, D., & Manser, C. J. (2019). Accretion of a giant planet onto a white dwarf star. Nature, 576 (7785), 61–64. https://doi.org/10.1038/s41586-019-1789-8

Citing Books

There are few new guidelines when you are citing a book. First, the publisher location no longer needs to be indicated.

%%Zack, P. O. (2001). The shoals of time. Bloomington, IN: First Books Library.

%%Zack, P. O. (2001). The shoals of time. First Books Library.

Second, the format of an ebook (e.g., Kindle, etc.) no longer needs to be indicated.

%%Niven, J. (2012). Ada Blackjack: A true story of survival in the Arctic [Kindle].

%%Niven, J. (2012). Ada Blackjack: A true story of survival in the Arctic .

Lastly, books from research databases without DOIs are treated the same as print works.

When using a URL in a citation, you no longer need to include the term “Retrieved from” before URLs (except with retrieval dates). The font should be blue and underlined, or black and not underlined.

Within a full APA citation, you may spell out up to 20 author names. For two to 20 authors, include an ampersand (&) before the name of the last author. For sources with 21 or more authors, structure it as follows:

Structure: First 19 authors’ names, . . . Last author’s name.

7th edition example: Washington, G., Adams, J., Jefferson, T., Madison, J., Monroe, J., Adams, J. Q., Jackson, A., Van Buren, M., Harrison, W. H., Tyler, J., Polk, J. K., Taylor, Z., Filmore, M., Pierce, F., Buchanan, J., Lincoln, A., Johnson, A., Grant, U. S., Hayes, R. B., Garfield, . . . Trump, D.

When creating an in-text citation for a source with 3 or more authors, use “et al.” after the first author’s name. This helps abbreviate the mention.

Generate citations in APA format quickly and automatically, with MyBib!

🤔 What is an APA Citation Generator?

An APA citation generator is a software tool that will automatically format academic citations in the American Psychological Association (APA) style.

It will usually request vital details about a source -- like the authors, title, and publish date -- and will output these details with the correct punctuation and layout required by the official APA style guide.

Formatted citations created by a generator can be copied into the bibliography of an academic paper as a way to give credit to the sources referenced in the main body of the paper.

👩‍🎓 Who uses an APA Citation Generator?

College-level and post-graduate students are most likely to use an APA citation generator, because APA style is the most favored style at these learning levels. Before college, in middle and high school, MLA style is more likely to be used. In other parts of the world styles such as Harvard (UK and Australia) and DIN 1505 (Europe) are used more often.

🙌 Why should I use a Citation Generator?

Like almost every other citation style, APA style can be cryptic and hard to understand when formatting citations. Citations can take an unreasonable amount of time to format manually, and it is easy to accidentally include errors. By using a citation generator to do this work you will:

• Save a considerable amount of time
• Ensure that your citations are consistent and formatted correctly
• Be rewarded with a higher grade

In academia, bibliographies are graded on their accuracy against the official APA rulebook, so it is important for students to ensure their citations are formatted correctly. Special attention should also be given to ensure the entire document (including main body) is structured according to the APA guidelines. Our complete APA format guide has everything you need know to make sure you get it right (including examples and diagrams).

⚙️ How do I use MyBib's APA Citation Generator?

Our APA generator was built with a focus on simplicity and speed. To generate a formatted reference list or bibliography just follow these steps:

• Start by searching for the source you want to cite in the search box at the top of the page.
• MyBib will automatically locate all the required information. If any is missing you can add it yourself.
• Your citation will be generated correctly with the information provided and added to your bibliography.
• Repeat for each citation, then download the formatted list and append it to the end of your paper.

MyBib supports the following for APA style:

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 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:

• 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 to one 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, 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.

Exercise \(\PageIndex{1}\)

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.

Exercise \(\PageIndex{2}\)

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 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”.

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.

Exercise \(\PageIndex{3}\)

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, 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. Section 13.2 and Section 13.3 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. (Section 13.3 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.
