EDITOR'S NOTE TO THE FIRST AMERICAN EDITION.
The original plan of Marx, as outlined in his preface to the first German edition of Capital, in 1867, was to divide his work into three volumes. Volume I was to contain Book I, The Process of Capitalist Production. Volume II was scheduled to comprise both Book II, The Process of Capitalist Circulation, and Book III, The Process of Capitalist Production as a Whole. The work was to close with volume III, containing Book IV, A History of Theories of Surplus-Value.
When Marx proceeded to elaborate his work for publication, he had the essential portions of all three volumes, with a few exceptions, worked out in their main analyses and conclusions, but in a very loose and unfinished form. Owing to ill health, he completed only volume I. He died on March 14, 1883, just when a third German edition of this volume was being prepared for the printer.
Frederick Engels, the intimate friend and co-operator of Marx, stepped into the place of his dead comrade and proceeded to complete the work. In the course of the elaboration of volume II it was found that it would be wholly taken up with Book II, The Process of Capitalist Circulation. Its first German edition did not appear until May, 1885, almost 18 years after the first volume.
The publication of the third volume was delayed still longer. When the second German edition of Volume II appeared, in July 1893, Engels was still working on volume
