Citing Sources

Citation Examples in APA Format

Basic APA Reference Format

The basic APA format for a reference includes 4 elements: author, date, title, and source. The reference might also include a DOI or URL. In this tabbed box, there are specific examples for some of the most used types of references. See your instructor or the 7th Edition of the APA Manual for specific information on other types of resources that are not included in this reference guide.

Follow these guidelines for including DOIs or URLs:

  • If a print work has a DOI include it at the end of the reference. If it does not have a DOI, do not include a DOI or URL.
  • If an online work has a DOI include it at the end of the reference. If an online work has both a DOI and URL, only include the DOI. If an online work does not have a DOI, only include an URL if it leads the reader directly to the source. Do not use database URLs.
  • List DOIs and URLs as hyperlinks.
  • You can shorten a complex DOI at http://shortdoi.org

Other Examples

Generally, personal communications are indicated in the body of your writing and not in the reference list (because it is not a retrievable resource). However, if a professor requires that you include them in your reference list, check with that professor for the desired reference format. See the following examples for in-text citations for personal communications:

The interviewee explained his ideas (P.T. Samuels, personal communication, October 15, 2008). H. Matthews explained his ideas on the topic (personal communication, July 8, 2009).
