Primary sources are materials that provide firsthand testimony or the closest evidence to a subject under investigation. Researchers often use these firsthand accounts of specific events, or direct investigations to understand events from the viewpoint of people living during that time period. Primary sources include letters, diaries, photographs, newspaper articles, and pamphlets. For more information, check out the Primary Sources Guide.
