This work is a study of power and control in industry, and focusses upon the possibility of radical democratic innovations in control. In particular the problems of producer co-operatives in market systems are examined. Volume I presents a detailed analysis of the Scottish Daily News workers' Co-operative, and seeks to isolate the reasons for the abrupt failure of the enterprise. Volume II examines the political economy of the press, and the difficulties to be encountered by any attempt to launch a noncommercial newspaper committed to radical politics. Volume III presents a review of the historical development of producer co-operatives, case studies of the two other co-operatives launched with the assistance of Department of Industry funds in 1975, KME and Triumph Meriden, discusses contemporary co-operative theory, and considers the extent of current co-operative development.
