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 to 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 an original object or document or 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 Creative works, e.g. poetry, drama, novels, music, art Handwritten manuscript Letters between two people A diary Historical documents, e.g. Bill of Rights Relics or artifacts, e.g. pottery, furniture, clothing, buildings
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 Literary criticism analyzing a novel, poem or play 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 catalogue
