In addition to print 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 a 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.
You can also search for an important historical figure as AUTHOR in the catalog. This will retrieve any published works or collections of papers written by that person.
