Primary and Secondary Sources

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.

  • First person account of an event
  • First publication of a scientific study
  • Speech or lecture
  • Original artwork
  • Novel (fiction) or film
  • Handwritten manuscript
  • Letters between two people
  • A diary
  • Historical documents, e.g. Bill of Rights

Secondary

A secondary source is one step removed from the primary original source. The author is reexamining, interpreting and forming conclusions based on the information that is conveyed in the primary source.

 

  • Journal article reporting on a scientific study
  • Newspaper and Magazine articles
  • Review of a music CD or art show
  • Critique of a work of fiction or film
  • 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.

  • Indexes and Bibliography
  • Encyclopedias and Dictionaries
  • Library catalog
  • Most textbooks
  • Guidebooks
