"The works collected here are but a small part of what Engel's wrote in connection with Marx's Capital. For over half a century, Engel's creative activity was closely interwoven with that of Marx....The first part of the collection consists of three reviews of the first volume of Capital. After the publication of the first volume in 1862, one of the tasks of Marx and Engels was to break the conspiracy of silence by which the bourgeoisie hoped to strangle at birth the doctrine of the hated....The second part of the collection consists of the synopsis of the first volume of Capital, written by Engels...The third part of the collection is an essay intended as a supplement to the third part of Capital, written by Engels in the last year of his life and published after his death." -- from the foreword.

"The reviews and the synopsis made by Engels are inestimable aids to the study of Capital. The contents of Capital are given for the greater part in Marx's own words.The centre of gravity, in the synopsis, as well as in the reviews, lies in the theory of surplus-value, the corner-stone of Marx's economic doctrine. Engels summarized Marx's theory of surplus-value with special care, characterizing in detail the historical circumstances in which the relations of capital exploitation spread, the working class made its first steps in the struggle and the first skirmishes took place between labor and capital. Engels' synopsis that the transition from one category to another is not a freak of reason but the reflection of the real historic process of development. Keeping to the order of Marx's exposition, he shows how, in the course of historic development, capital emerged on the basis of commodity production, how it subordinated to itself the whole of production, how simple co-operation was replaced by manufacture and this, in turn, by machine production." -- online
