Primary sources are generally defined as first-hand accounts of events. They may be published (in books or articles) or unpublished manuscripts. A primary source is an original work, not derived from other sources, and include first-person accounts, such as diaries, letters or interviews, official government records and court records. Visual records, such as painting or photographs, as well as films, television programs and even advertisements are also primary sources.
Look for primary sources in the MSU Catalog by utlizing the following terms in a Keyword search. For example, primary sources for the Central American revolutions and civil wars may include terms like these in the Subject headings, but start by using them in keyword searches.

For example, try using the above terms combined with "revolution*," "coup," "nationalism," etc., and with a place name, like Cuba, Southern Cone or Latin America.
