In scholarship, a secondary source[1][2] is a document or recording that relates or discusses information originally presented elsewhere. A secondary source contrasts with a primary, or original, source of the information being discussed. A primary source can be a person with direct knowledge of a situation or it may be a document created by such a person.

A secondary source is one that gives information about a primary source. In a secondary source, the original information is selected, modified and arranged in a suitable format. Secondary sources involve generalization, analysis, interpretation, or evaluation of the original information.

The most accurate classification for any given source is not always obvious. Primary and secondary are relative terms, and some sources may be classified as primary or secondary, depending on how they are used.[3][4][5][6] A third level, the tertiary source, such as an encyclopedia or dictionary, resembles a secondary source in that it contains analysis, but a tertiary source has a different purpose; it aims to elaborate a broad introductory overview of the topic at hand.[1][7]

Since a source is only a source in a specific historical context, the same source object can be both a primary or secondary source according to what it is used for.
