Q. Hello. I’m organizing a bibliography with multiple sources from the same author, including several introductions she’s written. Would all the introductions be alphabetized under I for Introduction?
A. Yes, and then all the introductions should be sorted into alphabetical order by book or article title. See CMOS 14.110 for how to style a bibliography entry for a book introduction.
