In addition to manuscript archives and digitized collections, primary sources can also be found in book form, published as collected documents or as appendices in a secondary source. When searching the catalog for books, keep an eye out for published primary sources in the stacks.
In combination with a subject term or keyword on your topic, the following search terms can help you focus in on primary sources in the catalog:
"Personal narratives" - used to designate memoirs or autobiographical accounts of a war or event.
"Diaries" - a less commonly used catalog term, but still valuable.
"Correspondence" - used to describe personal letters or the collected correspondence of an individual or class of persons (e.g. soldiers).
"Interviews" - often used to describe oral histories in print, audio, and video formats.
"Sources" or "Archives" - describes collected documents of all kinds.
