APA Overview
Tools for Formatting Your Citations
When searching library databases for your sources, use the Cite tool and select APA to copy and paste the citation for that source.

APA In-Text Citations

An in-text citation allows your reader to track down a specific source you use in your paper. The in-text citation should provide enough information to point your reader to the full citation in your reference list. An in-text citation must be included when you quote or paraphrase information from one of your sources.

In APA Style, an in-text citation typically includes the author's last name and the date of publication, in parenthesis. If you use a direct quote, include the page number for the reference. For three or more authors, include the first author followed by et al. (Smith et al., 2009, p. 16).

Examples from OWL at Purdue and APA Style Blog:

  • Double-space all reference entries.
  • Use a hanging indent (instructions for Word or Google Docs) where the first line of the reference is left-justified and all subsequent lines are indented.
