Augmentative and alternative communication (AAC) is a field which crosses many disciplinary boundaries. It is a rapidly changing field that uses the latest innovations and technologies to aid the language-disabled, and requires fluency not only in the hands-on technological aspect, but the service-delivery side as well. This well-written handbook addresses that need and is filled with practical information and extensive referencing. A valuable text for graduate students studying communication disorders and special education, the book would be a useful addition to the professional library of anyone working with AAC users, most especially for those working with children.TEXTBOOK
