Q. I’m wondering how to style a webinar series name and the title of an episode in that series. Should the series name be italicized and the episode title be in quotes?

A. CMOS is silent on webinar titles, but your suggestion is one possibility. Or you could put the series title in regular text (but without quotation marks), like book series titles and titles of academic courses.

[This answer relies on the 17th edition of CMOS (2017) unless otherwise noted.]
