Primary, Seconday & Tertiary Sources: Home

Explains the differences between these sources.

Welcome!

             

Most materials one finds in a library, such as books, documents, journals, and media, may be divided into either Primary or Secondary Source materials. They may be either print or electronic. Primary Source materials are quite often the “building blocks” upon which Secondary Source materials are based.
