This bibliography provides annotations on over 165 testing sources in the collection of the Humboldt State University (California) Library. Focus is on psychological and educational tests. Information resources are grouped according to information need, including sources of tests or information about tests, and by subject.

The section on test location contains a list of compilations or non-commercial tests and a section on national test information systems. The bibliography also contains sections on background information, strategy for use of appropriate indexes and abstracts, useful subject headings in the card catalog, a review of online resources, and groupings of evaluative testing sources listed by academic discipline.
