A primary source is an original object or document – the raw, source material or first-hand information – that was created during the time being studied.
This type of evidence varies by discipline and can include historical and legal documents, eyewitness accounts, results of an experiment, statistical data, pieces of creative writing, and art objects, to name a few. They are usually factual, rather than interpretive or critical.
Some examples of the difference between a primary source and a secondary source include:
The Diary of a Young Girl (primary) vs. ``The American History of Anne Frank`s diary`` (secondary)
``Sir Gawain and the Green Knight`` (primary) vs. ``Twentieth century interpretations of Sir Gawain and the Green Knight: a collection of critical essays`` (secondary)
A decorative amphora (primary) vs. a photograph of this ancient Greek vase (secondary)
