Primary Sources: What are they?
Primary sources are the raw materials of history, providing a window into the past and unfiltered access to the historical record. They are the first-hand accounts, in a range of formats, which were produced by people who lived during that period. In an archive of primary source materials, you’ll find a record of the cultural, social, economic, political, and scientific inquiries of the time.
For a more detailed explanation of the variety of different types of formats, visit the “Primary Sources at Yale” page.

Secondary sources help build your background knowledge about your topic. They are used to interpret primary sources, so you can think of them as report that is at least one step removed from the event or issue you are studying. In this sense, secondary sources are like second-hand accounts…
- If I tell you something, then I am the primary source.
- If you tell someone else what I told you, then you are the secondary source.
