The Test Collection in Ellis Library includes tests, assessment instruments, inventories and questionnaires covering a variety of subjects and disciplines. At the present time, the collection consists of some 2,000 items, primarily in microfiche format. Tests/instruments are also sometimes reproduced in books, dissertations and theses. In addition, citations and references about tests/instruments can be accessed by using various indexing sources. The approach that one takes will depend on the kind of information needed.
