Division TEACCH, located in the School of Medicine at the University of North Carolina at Chapel Hill, was one of the first programs in the country to understand that autism was an organic rather than a biologic condition. We were also one of the earliest programs to recognize the enormous variability in characteristics and behaviors of children described as autistic. For these reasons, the processes of diagnosis and assessment have always been important and central to our program. We are therefore extremely pleased to have a volume representing the most current thinking of the field's leaders in these important areas. As with the preceding books in our series, Current Issues in Autism, this volume is based on one of the annual TEACCH conferences held in Chapel Hill each May. The books are not simply published proceedings of the conference papers, however. Rather, conference participants are asked to develop a full chapter around their presentations. Other international experts whose work is beyond the scope of the conference, but related to the major theme, are asked to contribute chapters as well. These volumes are designed to provide the most current knowledge in research and professional practice available on the most important issues defining and clarifying autism.

Hidden Treasure is a follow up to Oaklander's first book, Windows To Our Children. Most of the books available in working with this population are written from a traditional 'play therapy' point of view. The Gestalt Therapy-based approach provides a more effective method for psychotherapeutic work with children of all ages. The focus is on the relationship between the therapist and client, rather than observation and interpretation. It is a vigorous, dynamic approach.Violet Oaklander uses a wide variety of creative, expressive and projective techniques in her work, and each chapter reflects and exemplifies the use of this work in the service of therapy. The approach is applicable to a wide variety of ages, as well as individual, family and group settings. The book will interest child and adolescent psychotherapists, psychologists, social workers, counselors, interns, school personnel as well as graduate-level students. Parents may also find it helpful, as well as adults who are interested in the child within.
