APA 7th Edition

This guide reflects the latest version (7th edition) of the Publication Manual of the American Psychological Association.

What Is APA?

APA stands for American Psychological Association and is a common formatting style for publications, including research papers, in the social sciences. APA style has unique formats for in-text citations and reference pages. Its style and guidelines increase the ease of reading comprehension for viewers as well as ensure consistent presentation of content and written material.

In APA, you must cite sources that you have paraphrased, quoted, or otherwise refer to in your research paper.

Cite your sources in two places:

  1. In the body of your paper with an in-text citation.
  2. In the Reference list at the end of your paper.

Formatting

All citations should be double-spaced and have a hanging indent in a Reference list. A "hanging indent" means that each subsequent line after the first line of your citation should be indented by 0.5 inches.

DOIs and Permalinks

For sources found using OneSearch or a database, use the DOI (Digital Object Identifier), which is a type of permalink assigned to journal articles published online. If you have both a permalink and a DOI for an article, use the DOI.

The "Permalink" button in OneSearch is indicated by an icon made of two connected, gray links. With the large number of sources available online, it is common for citations to include a URL. It is important to note, however, that the URL you include for any of your citations should be a permanent URL (or permalink), one that will stay active past the time that you are on that webpage.
