A primary source is firsthand testimony or direct evidence concerning a topic under investigation. Primary sources in history are generally created by people during the time period you are studying. Note: Instructors often have specific definitions for individual classes. If in doubt, ask.
Primary sources may include such things as ads, diaries, speeches, autobiographies, interviews, letters, photographs, government documents, newspaper stories, television and radio broadcasts, and even everyday items of all kinds, such as clothing, toys and furniture.
Consult Going to the Sources (REF D16 .B893) for advice and suggestions on doing historical research and writing.
