Note on Tests & Instruments: The Medical Library does not have a collection of tests. Many of the following sources are indexes to tests and reviews of tests. Here are some additional guidelines for locating tests.

• Many tests are owned by, and must be purchased directly from, the author or publisher.

• Using the resources in this guide can help identify the publisher and/or author. The library does not purchase individual tests.

• Tests may also appear online, with or without a fee, or appear in print or electronic books or journals.
