Diagnostic and Statistical Manual, 5th ed.
The UML Library does not own an eBook version of the DSM-5 but there is a copy in the Internet Archive, (link below.) To access the book create an account in the Internet Archive. The button says you can only check the title out for an hour but once you log in you will see a drop down allowing other check out periods. You can download the book if you have Adobe Digital Editions on your computer. Once you have borrowed the book and read the parts you need, be sure to click the "Return Now" button even if you plan to use the book again.
