None of the Above
Q. I’m doing a report on typographic systems and thought it would be great to analyze the guide that everyone uses. I can’t find anything on who designed your style guide, what typeface was used, and why. Is there a resource you can point me to or provide the information?
A. Our guide is designed by the in-house design staff at the University of Chicago Press. The book’s colophon (p.  of the print edition) gives the other information you’re looking for, including information on the fonts (“Composed in Mitja Miklavčič’s FF Tisa and Hoefler & Frere-Jones’s Whitney”). You can also find the colophon at CMOS Online.
