Primary Sources

What are primary sources?

Primary Sources provide first-hand accounts of the events, practices, or conditions you are researching.

These sources are usually created by someone who witnessed or experienced events and documented them at the time they happened. Primary sources can appear in may formats including pamphlets, manuscripts, data, dissertations, speeches, government documents, maps, objects and artifacts, sound recordings and visual materials.

Primary sources can also include first-hand accounts that were created later in items like autobiographies, memoirs, and oral histories.

  • sources
  • diaries
  • letters
  • personal narratives
  • speeches
