History Day Research @ the MNHS Library: Step 2: Online Primary Sources

Online Primary Sources Links

Useful Terms

Primary Source - Materials from the time of the person or event being researched.  (Letters, diaries artifacts, photographs, and other types of first-hand accounts and records, as well as reminiscences and oral histories. Stories from newspapers of the time may also be primary sources.)

Secondary Source - Materials that were created at a later time.  They analyze and interpret primary sources; footnotes or bibliographies can lead to primary sources.
