A guide to the major citation styles


Why cite?  Citing your sources:

  • Supports your claims and helps readers understand your viewpoints.
  • Shows readers how you arrived at your positions on issues.
  • Gives credit to the authors whose works you use.
  • Helps your readers find other works on the same topic.
  • Allows your readers to check your sources if they have any questions.

This guide is designed to help you understand and use the major citation style guides.  Click on the tabs above or the links below to navigate this site.
