Chicago Manual of Style is now in its 17th edition. We have updated our citation guides, check them out here - https://librarybestbets.fairfield.edu/citationguides
Some of the changes:
Notes-Bibilography:
-Ibid is no longer preferred in notes, instead the shortened citation should be used.
Example:
1. Barbie Zelizer, Remembering to Forget: Holocaust Memory through the Camera's Eye (Chicago: University of Chicago Press, 2003), 3.
2. Zelizer, Remembering to Forget, 11.
The title of the source could be removed if there are multiple notes of the same source but the page number must always be included.
3. Zelizer, 15
Author-Date:
-In a reference list, the year may be repeated for sources that are also identified by month and day.
Example:
Germano, William. 2017. “Futurist Shock.” Lingua Franca (blog). Chronicle of Higher Education, February 15, 2017. http://www.chronicle.com/blogs/linguafranca/2017/02/15/futurist-shock/.
