Searching for Primary Sources

What Is a Primary Source? A primary source is a resource that is an original, first-hand, or direct account or record from a time period, place, or people. It is usually created, written, or made during or close to an event, time period or by the person. A secondary source provides information that restates, examines, or interprets information from primary sources.
