What is a primary source? video from Shmoop
Primary sources are materials created at the time of the topic you are researching, or by an eyewitness to the topic. Primary sources enable the researcher to get as close as possible to what actually happened during a historical event or time period. They are not a commentary about your topic but are the topic you are commenting about.
Primary sources may include:
