No database provides free, full-text copies of all tests and measurements.
The person who creates the test decides if, when, and how it will be published. Some publish their tests in books and journal articles. Others have sold the “rights” to their tests to a publishing company, and now the publisher distributes (sells) the test.
Sometimes you can find a complete test in these sources, but most times they just provide you with information about the test or a shortened version of the test.

I would like to thank Bernadette Lear, Librarian at Penn State Harrisburg Library, for allowing me to borrow elements of her PSYC 571: Tests and Measures Library Guide and use them in this Library Guide. And also give credit to the American Library Association, Association of College and Research Libraries’, Social Work Liaison's Toolkit : Tests and Measures for assistance as well.
