Which Bibliographic Style to Use? I’m a nonfiction writer and am sometimes required to provide a bibliography with the final submission … be it a magazine article or a book … but not a dissertation. I’ve come across several bibliographic styles including: - University of Chicago … MLA … APA … and Turabian. Why the differences I wondered… and which style should I use? Or doesn’t it really matter that much for my purposes. Comments welcomed. Thanks.
