Except for a few minor differences, the overall style promulgated by Turabian is the same as The Chicago Manual of Style. While The Chicago Manual of Style is focused on giving style guidelines for publishing in general, Turabian is focused on student papers, dissertations, and theses (from Wikipedia).
The BU Writing Centre has created a summary of The Chicago Manual of Style footnote/endnote format and in-text citations (in Moodle).
A copy of the Turabian guide is available on reserve: A manual for writers of term papers, theses, and dissertations (Turabian) - Reserve LB2369.T8
The University of Wisconsin - Madison has created a good overview of Chicago style.
