Q. I would like to document, in a bibliography, information received in an academic class. Please send me the format for this application. Thank you for this service.
A. A live lecture could be cited like a paper presented at a meeting (CMOS 14.115). Accordingly, you would do something like this:
D’Erasmo, Stacy. “The Craft and Career of Writing.” Lecture, Northwestern University, Evanston, IL, April 26, 2000.
