Manuscript Preparation, Copyediting, and Proofreading
Q. In a book manuscript how much of the citation/location information for an image should I put into the image caption, and how much should go in the bibliography? Do images even need bibliography entries?
A. Image sources do not traditionally appear in the bibliography. The permission letter from the source of the image will specify which information must appear in the credit, but it’s usually an editorial decision whether to put the source credit in the caption or collect all the credits into a single section of the book.
