Das Kapital (Volume II)

“'Capital,' Volume II: The Process of Circulation of Capital. Having shown in Volume I how surplus-value is produced, Marx follows capital out of the factory and into circulation — the changing shapes it takes as money, production and commodities, the time and costs of its turnover, and finally the great exchange between the two departments of social production by which a whole economy reproduces itself, year after year, on the same or an expanding scale.”
