A primary source is an account of an event by a participant or eyewitness at the time. While often textual, primary sources may take other forms in various areas of research. Works of art, scientific or sociological data, archeological artifacts, and official government proceedings also constitute primary sources.
Examples of primary sources:
A secondary source interprets, discusses or analyzes. Secondary sources are usually texts. An author of a secondary source may be distant in time or geography from the primary source analyzed. Or a secondary source may be based on other secondary sources.
Examples of secondary sources:
Secondary sources are located by a key word search in one of the subject databases, such as Historical Abstracts, or by a key word or subject search in the Library Catalog. Sometimes secondary sources help in finding primary sources, since primary sources may be listed in the article’s footnotes or bibliography.
For finding primary sources, it is usually necessary to first gain some background about the research subject to know what kind of primary source is appropriate. Are statistics needed or a congressional hearing or a memoir? Then the appropriate database or catalog can be accessed. Please consult a reference librarian with any questions about working with primary and secondary sources.
