Point your Internet browser to the Criss Library website at http://library.unomaha.edu, look for the Research Tools column on the left side of the homepage, and click into the All Databases A-Z directory:
Once in All Databases A-Z, click on the alphabetical navigation or scroll down to find the link to the PsycTests database, which serves as a "repository for the full text (when available) of psychological tests and measures as well as a source of structured information about tests of relevance to psychologists and professionals in related fields such as psychiatry, management, business, education, social science, neuroscience, law, medicine, and social work."
The Mental Measurements Yearbook with Tests in Print database may also prove helpful in identifying instruments, but it focuses on commercially-published tests which typically must be purchased from the publisher(s), and the database rarely includes actual copies.
