Citing Sources: APA Citation Style

Learn how to cite your sources using a citation style.

What is it?

American Psychological Association (APA) is most commonly used to write papers and cite sources within the sciences and social sciences.

**If you are not sure which citation style to use, please ask your instructor.

 The purpose of documentation is to:

  • Identify (cite) other people’s ideas and information used within your essay, assignment or paper.
  • Indicate the authors or sources of these in a References list at the end of your paper.

This guide is based on the APA Manual (6th ed.) that was published in 2009.
