Learning About Primary Sources

“Nothing can be believed but what one sees, or has from an eye witness.” —Thomas Jefferson, July 19, 1789

What are Primary Sources?

"Primary sources are the raw materials of history — original documents and objects which were created at the time under study. They are different from secondary sources, accounts or interpretations of events created by someone without firsthand experience." - Library of Congress
