Primary Source vs. Secondary Source
A primary source is a document that shows direct, immediate or firsthand knowledge of a subject or event. It is a document written at the time or on the scene where an event occurred.
Secondary sources are those writings without direct knowledge of a topic or event. These include biographies, monographs, and general periodical articles.
