The Hoarding Handbook is a timely, relevant, rich resource for human service professionals working with persons who have a hoarding problem. The book offers a comprehensive perspective about hoarding - including the features of hoarding, its challenges and complexities, and the hoarding task force model to support coordinated intervention. Beyond a basic knowledge of hoarding, the book introduces assessment tools to help gauge the severity of a hoarding problem. The topics of mental health service systems, housing impact, public safety implications, the role of protective services, animal hoarding, legal system stakeholders, medical providers, and professional organizers are thoroughly discussed. The Hoarding Handbook is a resource that can be relied upon for helpful, focused perspective. As a clinician, I highly recommend this book.
