Citing Correctly and Avoiding Plagiarism

This is a guide to resources about avoiding plagiarism and citing sources correctly.

Examples of Chicago Style, 17th ed., Author-Date

Below are examples of common Chicago style citation formats. For the most authoritative guide to Chicago style, please consult the style manual.

Please note that this is the author-date format used in a reference list. Your professor will specify which format you should use for your citations.

A note about online sources: For any article or material you find online you will need the item's DOI or URL. A DOI is preferable to a URL when available. 

To create correct citations, ask yourself:

  1. Did I find the full text of this in print? If yes, no URL is needed.
  2. Did I find the full text of this in a database or on the open web? If yes, the DOI or URL is needed.
