This new handbook builds on The Handbook of Community Movements and Local Organizations published in 2007, and is the only resource defining the field of study related to small nonprofit organizations and to studying communities from the standpoint of associations that make up communities. It explores the history and conceptualizations of community, theoretical concepts in community organizations, social movements ranging from health to crime, and community practice methods. Further it provides authoritative statements of major theory areas, gives examples of different sub areas of the field, provides guidance to people working as practitioners in the field, and nicely coincides with the increasing interest in clinical sociology. This handbook is of great interest to academics, students and practitioners with an interdisciplinary resource to understand and collaborate in work with contemporary communities.
