Changes to Chicago Manual of Style Citations in the 17th Edition

Powered by Chegg

Earlier this year, The University of Chicago officially launched the 17th edition of the Chicago Manual of Style which provides some new guidelines for creating citations in research papers. We took a look at their updates and selected what we feel are the most important changes, which we have listed below. To help you keep up-to-date and understand these changes, we’ve also provided a few examples for each change.

Before we dive in, keep in mind that Chicago Manual of Style has two distinct types of citation formatting rules: Author-Date and Note-Bibliography. Be sure of which type you are using before you begin citing. Always check with your instructor if you are unsure of which type to use in your paper.

Changes in Author-Date Style

The publication year can now be repeated in some types of citations.

The year can now be repeated in citations that include the publication month and day.

Example:

Sutherland, Eleanor. 2012. “Do Bees Have Feelings?” Scientific American, February 15, 2012. Accessed April 4, 2012. http://www.scientificamerican.com/article.cfm?id=do-bees-have-feelings

Changes in Notes-Bibliography Style

The treatment of the title in website citations now depends on the website.

If the website has a print counterpart, such as the website for a newspaper, the title should be in italics. If it does not, it should not be in italics.

Examples:

  • The Daily News
  • The Wall Street Journal
  • Buzzfeed

 

Use of “ibid.” is no longer encouraged.

Instead, include a shortened footnote citation. To avoid repetition, the title of a work that has just been cited may be left out.

  1. Middlekauff, Glorious Revolution, 401–2.
  2. Middlekauff, 433.
  3. Jacobs, Women in Africa, 37–38.
  4. Jacobs, 201–2.
