This style is documented in Kate L. Turabian’s Manual for Writers of Research Papers, Theses, and Dissertations. Now in the 7th edition, it presents two basic documentation systems, notes-bibliography style (or simply bibliography style) and parenthetical citations–reference list style (or reference list style). These styles are essentially the same as those presented in The Chicago Manual of Style, 15th edition, with slight modifications for the needs of student writers. This style is designed for college students and business researchers.
