What is the Difference Between Primary and Secondary Sources?

Primary sources are the main source of data in the discipline of history. It is vital to learn how to access, evaluate, and incorporate them into your historical research.

 

Primary Sources:

  • Usually immediate, first hand accounts created by people who have a direct connection to the events and issues involved
  • Can be in any format - text, video, audio, image, etc.
  • May be digital or physical, but  are often rare or unique items of which there may be only 1 copy 

Examples: health records, meeting minutes and agendas, letters, laws, court rulings, newspapers

Secondary Sources:

  • Created by people removed from the events and individuals they discuss
  • Draw on primary sources to reconstruct and reflect on past events and personalities
  • May also be in any format, but usually they are available in many copies and produced on a mass scale by publishers.

Examples: journal articles, encyclopedias, conference proceedings, academic books
