Research Processes: Tertiary Sources

Role of Tertiary Sources

Tertiary Sources

Tertiary sources are introductory resources such as dictionaries and encyclopedias. These resources give students an introduction to their subject, to various subtopics within a larger topic if they are trying to narrow their topic, to the major voices on a topic, and (often) a bibliography with helpful secondary sources. Students should not spend a significant amount of time evaluating tertiary sources, but they should spend enough time on the tertiary sources to feel comfortable with their topic before moving forward to primary and secondary sources.
