Is the author's full name used in the reference page entry?

The usual advice is to take the information from the title page of the book or article. So if the author's name appears on the title page as Jim Y. Jones the name should appear in the references and bibliography as: Jones, Jim Y. Obviously, if the author has also published work under another name this should appear in square brackets after the name in the bibliography. (Do not include nicknames or facetious names).
