What is a Primary Source?

Primary sources are original materials. They are from the time period involved and have not been filtered through interpretation or evaluation. Primary sources are original materials on which other research is based. They are usually the first formal appearance of results in physical, print or electronic format. They present original thinking, report a discovery, or share new information.

Examples of primary sources include: artifacts, audio recordings, diaries, interviews, letters, newspaper articles, original documents, photographs, records of organizations, speeches, video recordings, and works of art.
