This is a long, heavy book. It consists of 51 chapters providing comprehensive reviews by respected, mostly North American authors. Each chapter presents the phenomenology, epidemiology and approaches to understanding, assessing and treating anxiety and related disorders, both psychologically and pharmaceutically. If you are a busy clinician I would not recommend buying this book, although that is not to say that it would not be interesting or useful. However, if you are a (clinical) researcher this book is likely to be very useful. If you are a mental health librarian I would advise buying this book, if you have not already done so.
