What is a primary source?
A source created by people who actually saw or participated in an event and recorded that event or their reactions to it immediately after the event. Examples: Original manuscripts, photographs, newspaper, oral histories, documentaries, historic sites, and artifacts are among the numerous and varied "eyewitness accounts" that can provide students with a richer and more descriptive explanation of the past than those found in traditional textbooks.
