APA Citations: Full Citations

This guide will help with APA formatting citations

APA Basics

In APA, you must cite the sources that you have paraphrased, quoted, or otherwise used to write your research paper.  Cite your sources in two places:

  1. At the end of your paper, you will provide a full citation for each source in a reference list.
  2. Within the text of your paper, you will provide an abbreviated in-text citation whenever you use information taken from a source.

Where Do I Find the DOI Link?

DOI Links

If your citation requires a link, try first to locate a DOI (Digital Object Identifier) for your source.  A DOI may be listed as a link or as a string of numbers and letters (for example: 10.1007/s12021-021-09517-8).  If the DOI appears as a string of numbers and letters, convert it to a link by adding https://doi.org/ to the beginning.  A DOI link is the best type of link to use in your APA citations.

Example: https://doi.org/10.1007/s12021-021-09517-8
