What’s New in the Chicago Manual of Style, 17th Edition


The 17th edition of the Chicago Manual of Style is here! The 17th edition, released by the University of Chicago, replaces replaces the 16th edition as the most current Chicago Manual of Style guide. It’s been seven years since the previous edition was released.

Now available on Citation Machine, the updated citation style has a few important changes from its predecessor. Let’s take a look at what’s new.

Main Changes in Notes-Bibliography Style

Titles for Websites

The treatment of titles of websites has changed slightly. 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. Here are a few examples.

New York Times
The Washington Post

Use of “ibid” 

In a departure from previous editions, Chicago Manual of Style 17 discourages the use of ibid. Instead, include a shortened footnote citation. To avoid repetition, the title of a work just cited may be omitted.

  1. Brown, Tokyo Cyberpunk, 401–2.
  2. Brown, 433.
  3. Christensen, Seeing What is Next, 37–38.
  4. Christensen, 201–2.

Main Changes in Author-Date Style

Repeating the Year in Certain Author-Date Citations

In an author-date reference list entry, the year may be repeated for sources that are also identified by month and day.
