I use this book consistantly as a reference. I find the straightforward uncomplicated prose makes this book one of the more readable of the genre. As a graduate student in psychology I find this a ready reference when writing papers. When I am in a professional position I am certain this book will be in my office within easy reach.
This book is a systemic version of the DSM. It looks at each disorder from a systemic perspective. This text is excellent. Everyone should read it, but it is a must for any systemic/family practitioners.
