Tertiary Sources

Tertiary sources are reference materials like Encyclopedias, Dictionaries, Handbooks, and Tables. They are collections of primary sources and secondary sources, that categorize and index information. 

Cite your sources!

A primary source is an original research article, experiment, or set of data. It is someone else's discovery, idea, or intellectual property, so you MUST cite a primary source correctly to give those researchers credit.
