Introduction to Unpublished Primary Sources

Manuscripts, letters, diaries and other personal records that have not been published will only be available through an archive or special collection library. It will be difficult to include these materials in a one-semester project unless they are local. If you need to travel for a capstone or thesis project be sure to apply for grant funding.

The unpublished source of data is the records that are maintained by the private firms, business enterprises, research works, scholars, etc.
