There are a number of databases that provide extensive information about tests and measures, though not the actual instruments themselves. One of these is the Mental Measurements Yearbook; another is Health and Psychosocial Instruments (HaPI). Both of these resources are accessible from the library's Databases list, and both are available through Ovid and use that platform's search protocols. The Database Field Guide for each of these files provides extensive information on database characteristics, content, and features.
It is also possible to search ERIC and PsycINFO by specific test name, since an instrument is sometimes introduced or included in a journal article, or occasionally made available as an ERIC document. It is worth checking Digital Dissertations as well, since a dissertation will sometimes include as an appendix an instrument used in its research study.
The College's Dean Hope Center for Educational and Psychological Services (CEPS) maintains a test collection, but access is restricted to authorized users. Please consult the website for further information.
