Types of Documents

Where to search for a specific type of document?

Primary and Secondary Sources

Primary sources
First-hand information, original documents, raw evidence.
E.g., speeches, interviews, photographs, original literature, statistical data.

Secondary sources
Second-hand information, interpretations, commentary, analysis of primary sources, original research.
E.g., most books, journal articles that analyse previous research studies, reviews, literary criticisms.

Tertiary sources
Summaries or condensed versions of materials, usually with references to primary or secondary sources.
E.g., dictionaries, encyclopedias, Wikipedia, handbooks, databases, bibliographies.


Primary sources are more credible as evidence, but secondary sources show how your work relates to existing research. They complement each other to help you build a convincing argument.

Tertiary sources do not provide original ideas or analysis. Instead, they collect, index, and provide insight from primary and secondary sources. This means that while you can use them to learn more about a topic you are new to, you are unlikely to cite them.
