A primary source is a document used in research that provides first-hand, direct evidence of a particular time period or event. These sources are either recorded directly at the time the event took place, or chronicled at a later date.
Some examples of primary sources are journals written at the time of an event, old newspapers detailing the event directly after it happened, minutes from meetings or gatherings and documented speeches. Other examples, in which events may have been recorded at a later date, include autobiographies, memoirs or other accounts written after the event by a person who was present at the time. Verified artifacts from the time period under research are also considered primary sources.
