What is a Primary Source?

      "Primary source is a term used in a number of disciplines to describe source material that is closest to the person, information, period, or idea being studied.  In the study of history as an academic discipline, a primary source (also called original source or evidence) is an artifact, a document, a recording, or other source of information that was created at the time under study. If created by a human source, then a source with direct personal knowledge of the events being described. It serves as an original source of information about the topic. Similar definitions are used in library science, and other areas of scholarship. In journalism, a primary source can be a person with direct knowledge of a situation, or a document created by such a person.      Primary sources are distinguished from secondary sources, which cite, comment on, or build upon primary sources, though the distinction is not a sharp one. "Primary" and "secondary" are relative terms, with sources judged primary or secondary according to specific historical contexts and what is being studied."
