Books in the Background information category below will give you definitions and helpful background information that will help you understand tests and measures as well as the research articles where you find them referenced.
The books in the Directories and Special Topics categories below will help you find reviews of tests by topic to help you find the test you need for your project. Many of these books even include contact information for the authors so that you can ask for permission to use their work.
Remember, our online database Mental Measurements Yearbook (in Step 1 of this guide) will also help you to find reviews and information about tests.
