Use Chicago Manual format for the “title” of the secondary source analysis (and for footnotes and bibliographies of all history papers). (Instructions for the secondary source analysis explain the “title.”)
There are two easy ways to find the correct format, both through Simpson Library’s “How do I . . . ?”:
1) Go to “Find a Database,” then “C,” and then Chicago Manual of Style Online. From there you can use the “Search” box, or you can use the table of contents: chapter 14, Notes and Bibliography.
2) Go to “Cite Sources,” then “Chicago/Turabian,” and then “Chicago/Turabian Print Sources.”
(Note: if you use a PDF, you are using an exact “copy” (vs. a non-print version which can vary significantly in font, spacing, pagination, even content ). Thus, use the documentation form for a print article. As Mr. Bales explains on page 8 of the guide to non-print sources, Important point: Because articles in PDF form look just like the original published articles, these types of works may be cited as print resources rather than non-print ones. When he meets with the class about documentation, Mr. Bales will emphasize the use of print format for PDFs.
