History: Primary Sources

Primary vs Secondary Sources

Primary sources provide direct or firsthand evidence about an event, person, or object. These sources are contemporary to the events and people described. In the context of historical research, primary sources are sources that were created during the specific time period being studied. 

Identifying primary sources

Determining if a source is a primary sources depends on your topic, the time period, and the context. Think who, what, when, where, and why.

Try to think about what your research question is. Who or what are you investigating? What time period? What area?

If the sources is a first hand or direct account about your topic, then it is a primary source!

Common examples of primary sources include:

  • Newspaper articles
  • Interviews
  • Letters
  • Diaries
  • Memoirs and autobiographies
  • Speeches
  • Pictures
  • Official documentation

  • Textbooks
  • General history books
