Citing Sources

APA Style Guides

When to Cite Sources

You must cite a source in all of the following situations:

  • Using a direct quote from another author
  • Paraphrasing the words of another author
  • Including another author's ideas, even if you disagree with them
  • Whenever you're not sure whether or not you need to cite a source

How to Cite Sources in APA Style

There are two steps involved in citing your sources correctly:

  • Include a short version of the citation in the text of the paper when you use the source. In APA style, the short version includes the author's last name and the publication date.
  • Include the full version of the citation in a list of references at the end of your paper.

You only need to include each source in the reference list once. But you must include an in-text citation every time you use a quote, idea, opinion, or fact from a source, even if you are paraphrasing or summarizing the source in your own words.
