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.
Secondary sources are works that analyze, interpret, or merely describe historical or scientific events. They’re written based on firsthand accounts without being firsthand accounts themselves. Secondary sources draw on the data and experiences from primary sources to reassess the information and draw conclusions by combining them with information from other sources.
