Citing Sources: APA

Currently APA 6th Edition

The information on this page is based on APA 6th edition.  We will update the examples to the 7th edition as soon as possible.

Key Points to Remember

APA requires in-text citations and a reference list.  References are cited in-text with author-date system and are listed alphabetically by author name in the Reference List.

Author names are inverted.  Example: Smith, J.D.

Reference lists should be double-spaced and in hanging indent format (indented 5 spaces).

Book titles and journal titles are italicized.  Article titles are not italicized.

Full journal titles are used rather than journal title abbreviations.

Include DOIs for online articles.  If DOI isn't available, include journal homepage URL.

Locating DOIs

If you have an article citation without a DOI, you can look up the DOI at CrossRef.org.

Likewise, if you have a DOI but not the citation information, you can look up the citation at DOI.org.

Some articles and journals do not provide DOIs--it is the publisher's preference to include or not to include a DOI. When citing an article without a DOI, check the style manual (AMA, APA, etc.) for guidance.

Examples of Journal Articles

Provide the DOI when it is available.  If the DOI is not available, provide the URL of the journal's homepage.  Do not list a retrieval date.  Do not put a period at the end of the URL or DOI.

Print articles are cited exactly like online articles except there is no DOI or URL included.

Reference List:

When there are 1-7 authors, list all authors in the reference list.  When there are 8 or more authors, list the first 6 authors, insert 3 ellipses, and add the last author.

In-text Citations:

For 1-5 authors, list all authors for the first in-text citation.  For all subsequent citations list only the first author followed by "et al."  For 6 or more authors, list only the first author followed by "et al."
