Below is a few videos and links intended to provide you with help using the Chicago (Tirubian) method of citation. You are expected to follow the guidelines presented in these videos. If multiple drafts are assigned, only the final draft need this completely done. My suggestion is to format informally while writing the essay, and formalizing them after completing the final draft.
(These videos were created by Amarillo College. Feel free to skip past the sections of the videos that are relevant only to students attenting that university).
