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.
