Primary sources provide first-hand testimony or direct evidence concerning a topic under investigation. They are created by witnesses or recorders who experienced the events or conditions being documented.
Often these sources are created at the time when the events or conditions are occurring, but primary sources can also include autobiographies, memoirs, and oral histories recorded later.
The medium of the primary source can be anything, including written texts, statistics, objects, buildings, films, paintings, cartoons, etc. What makes the source a primary source is when it was made, not what it is.

Examples of secondary sources include:
