This compilation of symposium papers on community power structure research focuses on the theme that community power structure research must shift away from case study methods and move toward aggregate data analysis. Advocating comparative analysis, seven authors present their views under the following topics: (1) Charles R. Adrian, "Several Loose Ends in Theory Building"; (2) Charles M. Bonjean, "Dimensions of Power Structure: Some Problems in Conceptualization and Measurement"; (3) Terry N. Clark, "Community Structure, Decisionmaking, Budget Expenditures, and Urban Renewal in 51 American Communities"; (4) Floyd Hunter, "The Application of Computers to Community Power Study"; (5) Harry M. Scoble, "Where the Pluralists Went Wrong"; (6) G. Ross Stephens, "The Power Grid of the Metropolis"; (7) John Walton, "Why Study Power Structures? A Critique and a Theoretical Proposal" and "An Exploratory Study of Decisionmaking and Development in a Mexican City". Discussion sessions are also included. (JF)
