The Duke University Libraries contain a wealth of primary materials for the researcher in U.S. history. The collections housed in the David M. Rubenstein Rare Book & Manuscript Library should not be overlooked. The holdings on the American South are particularly strong.
There are also many resources outside of the materials in the Rubenstein Rare Book & Manuscript Library. In the collections of the libraries outside of the Rubenstein Rare Book & Manuscript Library, primary resources take the form of published letters, diaries, and papers. To identify these resources in the online catalog (books and media), look for the subdivisions, correspondence, interviews, sources, diaries and personal narratives. Any of these terms can be used in the keyword search mode; for example, united states revolution sources.
