Primary & Secondary Sources

A primary source is first-hand information from a person who witnessed or participated in an event. It may also be scientific data, statistics, or an official transcript of a government proceeding. A secondary source is a description by a person usually not present at the event and relying on primary source documents for information. Secondary sources usually analyze and interpret.

The distinctions between primary and secondary sources can be ambiguous. An individual document may be a primary source in one context and a secondary source in another. Time is a defining element. For example, a recent newspaper article is not usually a primary source; but a newspaper article from the 1860's may be a primary source for civil war research.

Some examples of primary sources:

Diaries, memoirs, letters
Official documents and records
Original manuscripts
Period newspapers
Legal cases, transcripts, minutes, hearings
Interviews, oral histories, personal narratives
Research data and reports
Statistics
