Four facts to get you started
First--Chicago Humanities (Turabian) is a system of scholarly citation that uses foot- or end-notes and an optional bibliography. You will need to ask you professor whether they prefer a bibliography.
Second--If you include a bibliography, and it includes all works you have included in your foot- or end-notes, then you can use a shortened form of citation within your foot- or end-notes (see examples below).
Third--If, however, you are not including a bibliography, then the first time you mention one of your sources in your foot- or end-notes will need to include all the elements that make up a complete citation (see examples below).
Fourth--Tip for Perkins students: some or our faculty have been known to ask for a full bibliography and a full first citation. Please be sure you understand which your professor prefers.
