A primary source is a record or artifact produced during or shortly after a particular event, experience or time period by those who participated in or witnessed the event.
Examples include speeches, interviews, letters, census records, diaries, newspaper articles, government documents, clothing, photographs, posters, paintings, maps, court records, poems, plays, television and radio broadcasts.
To locate primary source materials in the library catalogue, conduct a keyword search and add sources, documents, diaries, or personal narratives or correspondence to other relevant search terms. For example, "cold war" (sources or diaries or documents)
You can find primary documents on the Web using similar keywords like those used to locate sources in the library catalogue and keywords such as eyewitness, first-hand accounts, oral history, autobiography, digital exhibition, digital collection, and primary sources.
Remember to critically evaluate all of your primary documents before you use them for your history paper.
