The successor to a volume on concepts and issues in urban citizen participation, this work documents selected patterns of participation, issues that trigger participation (school decentralization, housing needs, a proposed highway, and other crisis situations), and outside assistance as embodied in urban planning advocates, community development catalysts, and the training of community leaders, policemen, and others for participation. Newer forms of participation (the civil rights movement, people's organizations, inner city ministries, detached agencies, neighborhood law firms) are discussed. These are followed by accounts of community organizations at work in such localities as East Harlem, South Chicago, and Boston; the role of black caucuses in generating minority power; issues of participation in the Model Cities program; urban renewal efforts in New Haven, Philadelphia, and Cincinnati; pressure for greater local control of schools in Ocean Hill-Brownsville and elsewhere in New York City; successful protest and action in lower Manhattan and Cambridge, Massachusetts; attempts at dialogue in the Detroit ghetto; and examples of community development in Puerto Rico and India.
