Primary Sources
Hans Weingartz Leonce49
"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."

Tertiary sources are similar to secondary sources in that they both interpret primary sources of information. Tertiary sources, however, are usually condensed summaries and are useful as general reference material, offering definitions and overviews when you are starting on your research. Examples include;
