Author Guideline for APA styling

When writing academically, it is very important to properly cite and reference the materials used in your writing. Proper citation allows your readers to further explore your particular subject matter. Citing also protects you against plagiarism by clearly indicating and differentiating which information comes from other sources and which is your own work and writing. Following a uniform style, such as the APA style guide, helps display your facts, key points, and scientific findings simply and clearly for your readers. Finally, by following a uniform style, the publication process is more efficient for author and publisher alike, allowing for the swift and accurate typesetting of your work.

When using APA format, follow the author-date method of in-text citation. This means that the author’s last name and the year of publication for the source should appear in the text, for example, (Gershenkron, 1962).

Note: If you are referring to an idea from another work but not directly quoting the material, or making reference to an entire book, article, or other work, you only have to make reference to the author and year of publication and not the page number in your in-text citation. All sources that are cited in the text must appear in the reference list at the end of the paper.

APA Citation Basics

APA style specifies that major components of the paper (abstract, body, references, etc.) each begin on a new page with the heading centered at the top of the page. The body of the text is typically divided into sections with headings such as Method, Results, and Discussion. For an example of a paper properly formatted per the APA Manual, Sixth Edition, go to http://www.apastyle.org/manual/related/sample-experiment-paper-1.pdf Some papers have multiple studies in them so the body could have multiple sections and subsections within it.

Types of Citations

Integrated Citations

A work that is directly referenced within the text by the author’s, or multiple authors’, name is called an integrated citation. When there is an integrated citation for a work with multiple authors, separate the authors with the word “and.” For example:

Alm, Martinez-Vazquez, and Wallace (2009) questioned in their previous work validity of . . .

In an integrated citation that includes “et al.”, you would write the citation as such:

Kirchler et al. (2010) review the tax compliance decisions . . .

When writing an integrated citation for multiple citations, treat each citation as its own integrated citation. You would then separate the citations by a comma and an “and” between the last two citations.

The authors of Şenses (2015), Öniş (2016), Voyvoda and Yeldan (2016), and Taymaz et al. (2015) discuss in their research . . .


Parenthetical Citations

If the work is not directly referenced in the text but still needs to be cited, the citation will be moved to the end of the sentence, and the author’s name will be included along with the publication year, as in the following example: (Hobsbawm, 1991).

The page, or range of pages, where the information is found is identified by a “p.” for a single page or “pp.” for multiple pages. For example:

Although the APA style can seem difficult, it often is very easy to use once it has been practiced (Jones, 1998, pp. 24-32).

When you are citing an electronic, online material, or a source that doesn’t have a page number, use the paragraph number where the information is found. The paragraph number is indicated by “para.” An online source cited like this would look like this:

The APA style has shown a 25% increase in knowledge retention (Jones, 1998, para. 3).


If you are directly quoting from a work, you will need to include the author, year of publication, and the page number for the reference (preceded by “p.”). Introduce the quotation with a signal phrase that includes the author’s last name followed by the date of publication in parentheses, as in an integrated citation.

According to Jones (1998), “Students often had difficulty using APA style, especially when it was their first time” (p. 199).

If the author is not named in a signal phrase, place the author’s last name, the year of publication, and the page number in parentheses after the quotation, as in a parenthetical citation.

She stated, “Students often had difficulty using APA style” (Jones, 1998, p. 199), but she did not offer an explanation as to why.

The following section presents a more in-depth discussion of parenthetical and integrated in-text citations.

In-Text Citations: Author/Authors

In-text citations are used to show where you retrieved the information that you are using to make specific arguments in your writing.

Citing an Author or Authors

A basic citation will always use the author-date system. The pages the information is found on can also be included.

(Evans, 1992, pp. 139-140)

A Work by Two Authors

Name both authors in the parentheses each time you cite the work. Use the word “and” between the authors’ names within an integrated citation, and use an ampersand (&) in a parenthetical citation:

(Fine & Waeyenberge, 2013)

A Work by Three to Five Authors

List all the authors in parentheses the first time you cite the source. Include a serial comma before the ampersand.

(Johansson, Heady, Arnold, Brys, & Vartia, 2008)

In later citations, only use the first author’s last name followed by “et al.” (meaning “and others”) in parentheses. Note that in “et al.,” the “et” should not be followed by a period.

(Johansson et al., 2008)

Six or More Authors

Use the first author’s name followed by et al. for every citation, including the first.

(Kirchler et al., 2012)

Unknown Author

If there is no author listed for the source, cite the source by its title in the signal phrase, or use the first word or two in a parenthetical citation. Titles of books and reports are italicized or underlined; titles of articles, chapters, and web pages are placed in quotation marks.

A similar study was done of students learning to format research papers (“Using APA,” 2001).

In “Using APA” (2001), students learned to format research papers.

Note: In the rare case “Anonymous” is used for the author, treat it as the author’s name (Anonymous, 2001). In the reference list, use the name Anonymous as the author.

Organization as an Author

If the author is an organization or a government agency, write the organization’s full name in the signal phrase or in the parenthetical citation the first time you cite the source.

The purpose of the style was to give clarity and simplicity to the writing (American Psychological Association, 2000).

According to the American Psychological Association (2000), . . .

If the organization has a well-known abbreviation, include the abbreviation in brackets the first time the source is cited and then use only the abbreviation in later citations.

First citation: (Mothers Against Drunk Driving [MADD], 2000)

Second citation: (MADD, 2000)

Two or More Works Cited at the Same Time

When your parenthetical citation includes two or more works, order them the same way they appear in the reference list, separated by a semi-colon.

(Chang, 2006; Wade, 1990)

If multiple works by the same author or authors are cited simultaneously, use commas between the publication years, again, listing the sources in the same order that they appear in the reference list.

(Amsden, 1989, 1997)

Authors with the Same Last Name

To prevent confusion, use first initials when last names are the same. The first initial should appear before the last name of the authors.

(G. Johnson, 2001; P. Johnson, 1998)

Two or More Works by the Same Author in the Same Year

If you have two sources by the same author in the same year, use lower-case letters (a, b, c) with the year to order the entries in the reference list. Use the lower-case letters with the year in the in-text citation.

Research has shown (Allen, 2013a) that . . .

It was later discovered that these signs were indicative of a great underlying cause (Allen, 2013b).

Personal Communication

For interviews, letters, e-mails, and other person-to-person communication, cite the communicator’s name, the fact that it was personal communication, and the date of the communication. Do not include personal communication in the reference list.

Many students have difficulty with the APA style initially (E. Robbins, personal communication, January 4, 2001).

  1. P. Smith also claimed that many of her students had difficulties with APA style (personal communication, November 3, 2002).


Citing Indirect Sources

If you use a source that was cited in another source, name the original source (the source that was cited) in your signal phrase. List the secondary source (the source that cited the original source) in your reference list and cite the secondary source in parentheses.

Johnson argued that . . . (as cited in Smith, 2003, p. 102).

Unknown Date

If no date is given, use the abbreviation “n.d.” (meaning “no date”) in the place of a publication year.

Another study of students and research decisions discovered that students succeeded with tutoring (Sterling, n.d.).

Reference List

Unlike in-text citations, reference citations include additional details beyond author and date. Each reference citation is made up of four parts: Author, Date, Title, and Publication Data. This information will be listed at the end of your article under the subtitle “References.”

The following is a step-by-step guide to building a reference citation using each of these four parts.

Reference List: Author/Authors

The following rules for handling works by a single author or multiple authors apply to all APA-style references in your reference list, regardless of the type of work (book, article, electronic resource, etc.).

Single Author

List the author’s last name first, followed by the author’s initials. For example: Fowler, R. B.

Minns, J. (2001). Of miracles and models: The rise and decline of the developmental state in South Korea. Third World Quarterly, 22(6), 1025-1043.

Two Authors

List authors by their last names and initials. Use an ampersand (&) instead of “and,” and include a comma between them. For example: Musgrave, R. A., & Musgrave, P. B.

Musgrave, R. A., & Musgrave, P. B. (1989). Public Finance in Theory and Practice. New York: McGraw-Hill.

Three to Seven Authors

List authors by their last names and initials. Use commas to separate author names, while the last author’s name is preceded again by an ampersand. For example: Kirchler, E., Muehlbacher, S., Gangl, K. Hofmann, E. Kogler, C., Pollai, M., & Alm, J.

Kirchler, E., Muehlbacher, S., Gangl, K. Hofmann, E. Kogler, C., Pollai, M., & Alm, J. (2012). Combining Psychology and Economics in the Analysis of Compliance: From Enforcement to Cooperation. Tulane University Economics Working Paper 1212.

More Than Seven Authors

List the last names and initials of the first six authors, separated by commas. An ellipsis (. . .) will then be used, followed by the final author’s last name and initials. Never use et al. in a reference citation. For example: Miller, F. H., Choi, M. J., Angeli, L. L., Harland, A. A., Stamos, J. A., Thomas, S. T., . . . Rubin, L. H.

Miller, F. H., Choi, M. J., Angeli, L. L., Harland, A. A., Stamos, J. A., Thomas, S. T., … Rubin, L. H. (2009). Web site usability for the blind and low-vision user. Technical Communication, 57, 323-335.

Author with a Suffix (Jr., Sr., etc.)

When an author has a suffix as part of their name, such as Jr. (junior) or Sr. (senior), the suffix will appear after the initials of the author. A comma separates the initials from the suffix. For example: Downey, R., Jr.

Downey, R., Jr. (Actor). (2013). Iron man 3. Marvel Studios.

Organization as Author

When a book or article is written by an organization, the organization’s name takes the place of the author’s. Do not abbreviate. For example: American Psychological Association.

American Psychological Association. (2010). Publication manual of the American Psychological Association (6th ed.). Washington, DC: Author.

Unknown Author

When the author’s name is unknown, the title of the source will take the place of the author’s name.

Merriam-Webster’s collegiate dictionary (10th ed.). (1993). Springfield, MA: Merriam-Webster.

NOTE: When your chapter or article includes parenthetical citations of sources with no author named, use a shortened version of the source’s title instead of an author’s name. Use quotation marks (for articles) and italics (for books) as appropriate. For example, parenthetical citations of the source above would appear as follows: (Merriam-Webster’s, 1993).

Reference List: Date

The date in a reference citation will always appear in parentheses following the authors. Always include a period after the closing parenthesis. The following are examples of dates used in various reference scenarios, which will demonstrate how to organize your sources in the reference list.

Two or More Works by the Same Author

Use the author’s name for all entries and order the entries by year (earliest comes first).

Öniş, Z. (1992). The East Asian Model of Development and the Turkish Case: A Comparative Analysis. METU Studies in Development, 19(4), 495-528.

Öniş, Z. (1995). The limits of neoliberalism: Toward a reformulation of development theory. Journal of Economic Issues, 29, 97-119.

When an author appears both as the only author and, in another citation, as the first author of a group, list the one-author entries first, regardless of publication date.

Evans, P. (1995). Embedded Autonomy: States & Industrial Transformation. Princeton: Princeton University Press.

Evans, P., Reuschemeyer, D., & Skocpol, T. (1985). The state and economic transformation: toward an analysis of the conditions underlying effective intervention. In P. Evans, D. Reuschemeyer, & T. Skocpol (Eds.), Bringing the State Back In. New York: Cambridge University Press.

References that have the same first author and different second and/or third authors are arranged alphabetically by the last name of the second author, or the last name of the third if the first and second authors are the same.

Kirchler, E., Hoelzl, E., & Wahl, I. (2008). Enforced versus Voluntary Tax Compliance: The “Slippery Slope Framework”. Journal of Economic Psychology, 29, 210-225.

Two or More Works by the Same Author in the Same Year

If there are multiple references by the same author in the same year, organize them in the reference list alphabetically by the title of the article or chapter. Lowercase letters are then added to each publication year, listed alphabetically. The same also applies to groups of writers. If you use more than one source by a group of authors from the same year, attach a letter (starting with a) to the publication year.

Sturridge, D., Owen, M., & Reina, J. M. (2004b). Human and non-human actors in ANT. Hershey, PA: IGI Global.

Works with No Date of Publication

Some sources have no defined date of publication. In this case, write “n.d.” (no date) in place of the date.

O’Keefe, E. (n.d.). Egoism & the crisis in Western values. Retrieved from http://www.onlineoriginals.com/showitem.asp?itemID=135

Forthcoming Works

Use “in press” in the place of a date to cite a work that has yet to be formally published.

Öniş, Z., & Kutlay, M. (in press). The Dynamics of Emerging Middle Power Influence in Regional and Global Governance: The Paradoxical Case of Turkey. Australian Journal of International Affairs.

Reference List: Title and Publication Data

Reference List: Articles in Periodicals

Basic Form

APA style dictates that after the author and publication date information, described above, the title of the article is written in sentence case, meaning only the first word and proper nouns in the title are capitalized. The periodical title is written in title case (all words upper case except for articles, prepositions, and conjunctions), and is followed by the volume number, issue number and page numbers. The title of the periodical and the volume number will always be italicized.

Author, A. A., Author, B. B., & Author, C. C. (Year). Title of article. Title of Periodical, volume number (issue number), pages.

Article in a Journal Paginated by Volume

Journals that are paginated by volume begin with page one in issue one and continue numbering issue two where issue one ended. In this case, only the volume number and the page number are necessary.

Erdoğdu, M. M. (2001). The role of the state in national technological capability building, Review of Asian and Pacific Studies, 22, 17-41.

Article in a Journal Paginated by Issue

Journals paginated by issue begin with page one in every issue; therefore, the issue number is indicated in parentheses after the volume. The parentheses and issue number are not italicized or underlined.

Alm, J., Martinez-Vazquez, J., & Wallace, S. (2009). Do tax amnesties work? The revenue effects of tax amnesties during the transition in the Russian federation. Economic Analysis & Policy, 39(2), 235-253.

Article in a Magazine

Articles in works published more frequently, such as weekly magazines, will include the month and date of publication.

Henry, W. A., III. (1990, April 9). Making the grade in today’s schools. Time, 135, 28-31.


Article in a Newspaper

Unlike other periodicals, p. or pp. precedes page numbers for a newspaper reference in APA style. Use “p.” to denote a single page (e.g., p. B2) and “pp.” to denote multiple pages (e.g., pp. B2, B4 or pp. C1, C3-C4).

Schultz, S. (2005, December 28). Calls made to strengthen state energy policies. The Country Today, pp. 1A, 2A.

Letter to the Editor

For works other than articles, such as an editorial preface or letter to the editor, label the work in brackets following its title.

Moller, G. (2002, August). Ripples versus rumbles [Letter to the editor]. Scientific American, 287(2), 12.


For reviews, label the work as above, but also include the title and authors of the work being reviewed.

Erdoğdu, M. M. (2001). Review of the book State and Market: The Political Economy of Turkey in Comparative Perspective, by Z. Öniş, Turkish Studies, 2(2), 152-154.

Reference List: Books

Basic Form

In APA style, after the author names and the year of publication, the title of the book is written in sentence case and italicized (note that this is different from a journal reference). After the title, list the location of the publisher, followed by a colon and then the name of the book’s publisher.

Author, A. A. (Year of publication). Title of work: Capital letter also for subtitle. Location: Publisher.

Online Scholarly Journal Article: Citing DOIs

Because online materials can potentially change URLs, APA recommends providing a Digital Object Identifier (DOI) in your reference, if it is available, as opposed to the URL. DOIs can provide stable, long-lasting links for online articles, and are unique to their documents. Many, but not all, publishers will provide an article’s DOI on the first page of the document. Some online bibliographies will provide an article’s DOI but may “hide” the code under a button which may read “Article” or may be an abbreviation of a vendor’s name like “CrossRef” or “PubMed.” This button will usually lead to the full article which will include the DOI. A DOI from a print publication or one with a dead link can be found with CrossRef.org’s “DOI Resolver” (http://www.crossref.org/guestquery/).

Article from an Online Periodical with no DOI Assigned

Online scholarly journal articles without a DOI require the URL of the journal home page. Since one of the goals of citations is to provide your readers with enough information to find the article, providing the journal home page aids readers in this process.
