A primary source is a document, recording or other source of information created at the time being studied, by an authoritative source, usually one with direct personal knowledge of the events being described.
Primary sources include diaries, letters, family records, statistics, speeches, interviews, autobiographies, film, government documents, or original scientific research.
You can find many primary source materials via Library Search. Primary sources can also be found in Rose Library.
