Tertiary Sources

Tertiary sources are sources that identify and locate primary and secondary sources. These can include bibliographies, indexes, abstracts, encyclopedias, and other reference resources; available in multiple formats, i.e. some are online, others only in print.

It is important to note that these categories, i.e. secondary and tertiary, are not mutually exclusive. A single item may be primary or secondary (or even tertiary) depending on your research topic and the use you make of that item.
