Primary sources are materials that provide firsthand testimony to a subject under investigation. Researchers often use these firsthand accounts of specific events to understand events from the viewpoint of people living during that time period. Primary sources include letters, diaries, photographs, newspaper articles, and pamphlets. Primary sources also include writings and recordings by witnesses who experienced the events or conditions being documented. For example, oral histories, autobiographies, and memoirs are primary sources.
Primary source materials can be found in a variety of locations, including within books, newspapers, article bibliographies, and archives or manuscripts collections.
