None of the existing English editions of Marx’s Capital, Vol I, including the new Ben Fowkes translation published by Penguin in 1976, fully incorporate the text as revised by the author for his 1872-75 French edition. These omitted or alternate texts cover the subjects of the role of private property in capitalism, alienation and unskilled factory work, capitalist crises, unemployment, and imperialism. Finally, the French edition of Capital is viewed briefly in the overall context of the writings of Marx’s last decade, 1873-1883.
