"The books offer less experienced readers a broad understanding of the issues and also routes to particular topics. More advanced scholars can quickly update themselves on an entire field. And scholars and practitioners can fill in gaps in their experience and perspective by reviewing the chapters in their own fields...The writing is lively, which is unusual for a weighty handbook, and the reader comes away with a real sense of the continuum of research to practice...Summing up: Highly recommended. Upper-division undergraduates through faculty and professionals."
—J.F. Heberle, Albright College (Choice, April 2007)

"Overall, the volume is clear, comprehensive, and extremely well-written." (PsycCritiques, April 18, 2007)

"…is an internationally known, classic work spanning 75 years of research." (American Reference Books Annual, March 2007)
