CMM 676 - Qualitative Research Methods: Evaluating Primary Sources

This guide emphasizes the use of primary sources in research

It is a primary source?

 

Primary sources can include:  artifacts, audio recordings, diaries, internet communication, interview, letters, peer-reviewed journal articles, original documents, patents, photos, proceedings, records of organizations, speeches, videos, survey results, works of art, web sites.

Secondary sources are sources and information that is produced "after the fact" and are often interpretive in nature.  Examples of secondary sources include:  bibliographies, biographies, criticisms, commentaries, dictionaries, encyclopedias, histories, journal articles, monographs (except fiction and autobiographies), textbooks, websites.

Tertiary sources combine elements of primary and secondary sources. Examples of tertiary sources include:  almanacs, bibliographies, dictionaries, encyclopedias, factbooks, guidebooks, manuals, textbooks.
