ID 230: Assignment #3 - Distinguishing & Selecting Between Primary, Secondary, & Tertiary Sources

What is a Primary Source?

Primary Sources are created as close to the original event or phenomenon as it is possible to be. For example, a photograph or video of an event is a primary source. Data from an experiment is a primary source. Primary sources provide raw data. Primary sources allow researchers to get as close as possible to original ideas, events, and empirical studies as possible. 

Use primary sources when you want to make claims or criticisms, as evidence for theories, or to gain timely perspectives on a topic.

Some examples of primary sources are:

  • Artifacts 
  • Empirical Paper
  • Poems
  • letters
  • diaries
  • original paintings
  • interviews
  • speeches 
  • photographs 
  • oral histories 
  • films
  • government publications 
  • plays

 

EXAMPLES OF PRIMARY SOURCES
