Are there mystery novels where librarians have a prominent role?
Yes, and the best source of information is Marsha McCurley’s Bibliomysteries page, http://www.bibliomysteries.com/ . Besides an extensive bibliography, McCurley includes lists of librarian detectives, staff victims, reference works, links to other listings, and a collection of quotes: “…People just don’t get murdered in public libraries. It’s not done.” — Police Chief, in Murder in a Library by Charles J. Dutton Continuing in the literary mode: Don’t miss the Great Librarian-Poets, at Roth Publishing, http://www.rothpoem.com/poetlib.html.
