Turabian Style refers to "A Manual of Style" written by Kate Turabian, and is based on the Chicago Manual of Style. However, whereas the Chicago style is designed for professional publications, Turabian style is designed for students of college-level research papers, theses, and dissertations.
Turabian Style offers two different methods for formatting papers: Notes/Bibliography and Author/Date.
Be sure to check with your course instructor, and pick one style to use consistently throughout your paper. If your professor mentions using Footnotes, they are referring the Notes/Bibliography format.
You can use these Paper Templates to get you started with Turabian Style formatting. Or, if you would like to start from scratch in your preferred word processing program, you can use the guidelines in the Note/Bibliography and Author/Date pages of this Guide (hover over the Turabian tab up top to access them).
