If your Professor wants you to use Benjamin style, this is the book to use.
The Chicago Manual of Style is published and created by the University of Chicago Press for publishers, scholars, and students. The manual includes formatting guidelines for writers in all disciplines, but the citation style is used primarily by those in the humanities. Note: There are two formatting styles for the Chicago Manual of Style. The Notes-Bibliography system uses footnotes and an accompanying Bibliography page. The Author-Date system uses in-text parenthetical citations and an accompanying bibliography (References) page.
Turabian style was created by Kate L. Turabian (1893-1987), a secretary at the University of Chicago who worked with the graduate school dissertations and edited official publications. The manual is an introduction to Chicago-style formatting and citation generation, with a specific focus on student writers rather than professional writers. Turabian also features both Notes-Bibliography and Author-Date formatting.
