Research Essentials

Primary vs Secondary Sources

Primary Sources provide direct or first-hand evidence about an event, object, person or work of art.

  • Usually contemporary to the events and people described
  • May be written and non-written
  • Examples include:
    • diaries
    • works of art and literature
    • speeches
    • audio and video recordings
    • photographs and posters
    • newspaper ads and stories
    • laws and legislative hearings
    • plant and animal specimens
    • original research studies

Secondary Sources lack the immediacy of a primary record.

  • Produced sometime after an event happened
  • Contain information that has been interpreted, analyzed or processed
  • Often based on primary sources
  • Examples:
    • history textbooks
    • interpretive journal articles
    • book reviews 

Search Tips for Primary Sources

1. Choose a relevant database or digital collection to search. 

2. Enter relevant keywords.

3. If possible, limit search by publication date and format (e.g., book reviews, photographs).
(Many databases have this option.)

4. Consult a librarian for recommended databases and resources.
