The online catalog provides bibliographic information on the majority of holdings in the Duke University Libraries. Materials in the online catalog are cataloged using Library of Congress Subject headings. A listing of these headings is available through the multi-volume Library of Congress Subject Headings (commonly referred to as the "big red books"). Sets are available in both the Perkins Reference Department and Lilly Library. With subject searching, a good place to begin is with variations on the heading that begins with United States -- history. For example,
United States -- History -- Civil War, 1861-1865 -- Caricatures and cartoons
United States -- History -- Colonial period, ca. 1600-1775 – Bibliography
