This book is an anthology of nine short articles written by Tom O'Lincoln over a 30 year period. It includes five popular presentations of basic Marxist theory and two articles on the topic of the nature of the system in Russia and state capitalism. The other two chapters are on trade unionism - one on the development of the Marxist theory of trade unions from Marx to the Communist International and the other outlines the history of the Communist-led Minority Movement in Australia during the early 1930s.
