You might want to visit libraries which have collections of manuscripts, papers, organizational records, ephemera or other unpublished materials relating to the people, organizations and agencies involved in the events.  These are often original, one-of-a-kind materials.  Click on the link above for Hofstra University's Special Collections department.

Publications generated by a government body, public records, reports and statistics such as census records, laws, Supreme Court decisions and treaties are excellent sources of primary materials.  The John W. Wydler Government Information Depository of Hofstra University is a virtual depository designated by the U.S. Federal government.  Click the link above for information about the depository, guidance for using the collection, and contact information for additional help.

Please note:  Congressional Publications also provides access to many Congressional Research Service Reports (CRS).  These reports are published to provide non-partisan research to U.S. congress.  The reports are authored by experts and cover many topics.  They are especially useful to students.
