Primary vs. Secondary vs. Tertiary Sources

When evaluating the quality of the information you are using, it is useful to identify if you are using a primary or secondary source. By doing so, you will be able recognize if the author is reporting on his/her own firsthand 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
  • Handwritten manuscript
  • Letters between two people
  • 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  • Historical documents, e.g. Bill of Rights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.
  • 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.
  • Bibliography
  • Index to articles
  • Library catalog
