Citation, Documentation of Sources

Q. I am editing a document in notes/bibliography style where the author has wordy footnotes rather than straight-up citations. For example: “There are a number of excellent biographies of Jane Austen and the outlines of her life story are nearly always rehearsed in articles on her work. Jane Doe, her friend, wrote the first authoritative biography. Joe Blogg’s Her Life Story is perhaps now the definitive. And John Doe’s short biography for the Penguin Lives Series has circulated widest.” And it goes on with several more. Since these sources are all in the bibliography, do I need to include all of the publishing info in the footnotes? We’re trying to keep them short.

A. You’re in luck: shortened note citations are actually preferred when there is a bibliography. Please see CMOS 14.29.
