Library:Guide to Finding Primary Sources/Preamble
What are Primary Sources?
Primary Sources are the direct evidence or first hand accounts of events without secondary analysis or interpretation. A primary source is a work that was written or created at a time that is contemporary or nearly contemporary with the period or subject being studied.
The definition of a primary source can change depending upon the academic discipline and the context in which it is used - Humanities, Social Sciences and Sciences have unique types of materials which qualify as primary sources.
