The Chicago Manual of Style (16th ed.) Chicago : The University of Chicago Press, 2010 REF Z253 .U69 2010 is kept in the Library's reference collection. Please ask for it at the Reference Desk if you should need information about proper citation that cannot be answered by the History Department's own "modified Chicago" style sheet.
Consider consulting OWL - the Online Writing Lab at Purdue University - for an online guide to Chicago style formatting for periodical article citations.
