Primary vs Secondary Sources

When evaluating the quality of the information you are using, it is useful to identify if you are using a Primary, Secondary, or Tertiary source. By doing so, you will be able recognize if the author is reporting on his/her own first hand experiences, or relying on the views of others.

Source Type Examples

Primary
A primary source is a first person account by someone who experienced or witnessed an event. This original document has not been previously published or interpreted by anyone else.

 

  • Diaries
  • Letters
  • Photographs
  • Art
  • Maps
  • Video and film
  • Sound recordings
  • Interviews
  • Newspapers
  • Magazines
  • Published first-hand accounts, or stories                                        

Secondary

  • Newspaper reporting on a scientific study
  • Review of a music CD or art show
  • Biography
Tertiary
A tertiary source is further removed from primary source. It leads the researcher to a secondary source, rather than to the primary source.
