The Diagnostic and Statistical Manual of Mental Disorders (DSM) is an American handbook that lists different categories of mental disorders and the criteria for diagnosing them, and is widely used by mental health professionals worldwide, including "clinicians and researchers as well as insurance companies, pharmaceutical companies and policy makers" (wikipedia). To say that it's something of an influential document is a bit of an understatement.
