Primary, Seconday & Tertiary Sources: Secondary Sources & Tertiary Sources

Explains the differences between these sources.

What is a Secondary Source?

 

        

Secondary Sources - most often interpretations or analyses of primary source information. Mostly in the form of books, journal articles, and reference materials.

The disctinction between primary and secondary sources is not solely based on book vs. article format. A book of interviews would be a primary source about that person; a book of scholarly criticism of that person's work would be a secondary source. 

 

secondary source of information is one that was created later by someone who did not experience first-hand or participate in the events or conditions you're researching. For the purposes of a historical research project, secondary sources are generally scholarly books and articles. Aug. 23, 2006 Definition of secondary source - University of Illinois Library.  www.library.illinois.edu/village/primarysource/mod1/pg2.htm
