What is APA?

APA style was created by the American Psychological Association. It is a set of rules for publications, including research papers.

In APA, you must cite sources that you have referenced, 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 References list at the end of your paper.

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.
