"If you frequently read contemporary psychiatric, psychological, or sociologic literature, you should own this dictionary. That it has continued into a seventh edition is probably more convincing praise than I can give. If you own the sixth edition, you should consider buying the new one: Campbell has added more than 2000 new terms and has taken pains to incorporate new terms and diagnostic criteria from the Diagnostic and Statistical Manual IV of the American Psychiatric Association. And for a book of this size and content, its price is eminently fair."--Annals of Internal Medicine
