=The Standard Socialist Series.= This volume is a fair sample of the twenty-five socialist books already published in this library. In their selection, the object of the publishers has been in so far as possible to include all the greatest works by European and American socialists that could possibly be brought within the limits of a fifty-cent volume. Of course the series includes the =Communist Manifesto,= by Marx and Engels. This, by the way, is published in two editions, in one of which is also printed Liebknecht’s work on socialist tactics entitled =No Compromise=, while the other includes a version of the Manifesto in Esperanto, the new international language, as well as the English version. The Standard Socialist Series also includes Marx’s =Revolution and Counter-Revolution=, and three of the most important works of Frederick Engels, =Socialism: Utopian and Scientific=, =The Origin of the Family, Private Property and the State=, and =Feuerbach: The Roots of the Socialist Philosophy=. As for living socialist writers, France is represented in this library by Lafargue’s =Social and Philosophical Studies= and =The Right to Be Lazy and Other Studies=, Germany by Kautsky’s =The Social Revolution= and =Ethics and the Materialist Conception of History=, Italy by Ferri’s =The Positive School of Criminology=, Russia by Plechanoff’s =Anarchism and Socialism=, Belgium by Vandervelde’s =Collectivism and Industrial Evolution=, England by Blatchford’s =Britain for the British=, and America by the writings of Isador Ladoff, Roberts Rives LaMonte, A. M. Simons, John Spargo, Ernest Untermann, John M. Work and others. Full descriptions of all these books, together with an account of our other books at higher and lower prices and suggestions as to the choice of books, together with some interesting propaganda matter, will be found in the current issue of the Socialist Book Bulletin, mailed free to any one requesting it.
