When to Cite Sources

The purpose of using citations is to let the reader know where you obtained your information so sources can easily be located and consulted. You must document your sources when you provide information that you ordinarily would not have known before conducting your research.

You must cite when you:

  • Discuss or paraphrase someone else's ideas
  • Provide a direct quotation
  • Use statistical or other data


 The Chicago Manual of Style Online provides some brief information and examples of this form of citation. 

The OWL at Purdue provides useful resources and sample citations in Chicago Style. 

You can also find information about Chicago Style at the University of Wisconsin - Madison Writing Center.
