Citing sources in APA style

Crediting sources and formatting references according to the style of the American Psychological Association (APA). Based on the 6th edition of the Publication Manual of the APA.

Journal article references: general form

The general form of a journal article reference is:

Author, A. A., Author, B. B., & Author, C. C. (year). Title of article. Title of Periodical, Volume number, pages. https://doi.org/xx.xxxxxxxx

Most journals have both volume numbers and issue numbers for the issues within a volume. You include the volume number. Only include the issue number if each issue starts again at page number 1.

If the author is not known, the title of the article moves to the author position.

Finish with the DOI if there is one. Also when you have consulted the printed version of the article.

Journal articles: printed and electronic form

Journal article published in printed form only

Hemels, J. (1987). Abonneeverzekering en oplagemarketing. Massacommunicatie, 15, 207-220.

You only include the issue number if the journal is paginated by issue. If that is the case, include it in parentheses after the volume number, f.i.15(6), 2-12. This is not common practice in scholarly journals. Most are paginated by volume: issue 2 begins where issue 1 ended etc.

 

Journal article with DOI

Koopmans, R., & Muis, J. (2009). The rise of right-wing populist Pim Fortuyn in the Netherlands: A discursive opportunity approach. European Journal of Political Research, 48, 642-664. https://doi.org/10.1111/j.1475-6765.2009.00846.x

  • If an article has page numbers, include these preceding the DOI.
  • If an article has an article number, the article number should be omitted, but page numbers should be included. You can find the page numbers after opening the PDF version of the article.
    If page numbers are missing (article is only available as web text), just leave off this part of the reference and place the DOI directly after the volume number.

 

Journal article with DOI, more than seven authors

Berry, T. R., Spence, J. C., Plotnikoff, R. C., Bauman, A., McCargar, L., Witcher, C., . . . Stolp, S. (2009). A mixed methods evaluation of televised health promotion advertisements targeted at older adults. Evaluation and Program Planning, 32, 278-288. https://doi.org/10.1016/j.evalprogplan.2009.05.001

  • If an article has more than seven authors, include the first six, then three periods (with spaces) and then the last author.
  • In text the citation is: (Berry et al., 2009)
  • If an article has seven authors or less, include all authors in the reference list.

  • This is an advance online publication. After a period of time it is replaced by a final version.
  • The advance online article has a DOI, but not yet a volume number, issue number and page numbers.
  • If there is no DOI, include the URL of the journal.
  • Before publishing your own work or handing in your paper, check if there is a final version that you can use for referencing,

 

Article that is difficult to access via the journal: reference via a database

  • Sometimes you have to deal with older articles from journals that no longer exist and which have been digitalized but are only accessible through databases such as JSTOR or ERIC. Then you can reference via the database.

Magazine article

A magazine is a special kind of journal: a popular or professional journal with illustrations and advertisements. Most of the scholarly journals are not magazines and can be seen as proper journals (see the examples above).

Magazine article
