Q. I am writing a long research paper, and in almost every page the footnotes take up nearly half the page. Most of my sources have URLs with them; am I allowed to take out all of the URLs in the footnotes if they are included in my bibliography?
A. You should ask your instructor what’s allowed, but as far as Chicago is concerned, footnotes may consist of short citations (author, short title, page number) when there’s a bibliography to provide full citations. Please see CMOS 14.23.
