Since Webster’s dictionary (both printed [second edition, 1955] and on-line [http://www.m-w.com] versions) defines "handbook" as "capable of being conveniently carried as a ready reference," I was pleasantly surprised and delighted that this veritable cornucopia of psychological assessment data is not a pocket-size manual. At 3 lb, 12 oz, this book is heavier than the 2-lb, 4-oz weight of my treasured and highly valued copy of Psychodynamic Psychiatry in Clinical Practice(1). Professor Groth-Marnat of Pacifica Graduate Institute in Santa Barbara, Calif., achieves his objective of "integrating the best of science with the best of practice" (p. xiii).
