For propaganda purposes, in addition to a big list of cheap pamphlets, many of them small enough to enclose in a letter to a friend, there are a number of cheap books. These have been specially written for beginners, most of them for workingmen. Here, for example, one picks out at a random shot Work's "What's So and What Isn't," a breezy little book in which all the common questions about Socialism are answered in simple language. Or here again we pick up Spargo's "The Socialists, Who They Are and What They Stand For," a little book which has attained considerable popularity as an easy statement of the essence of modern Socialism. For readers of a little more advanced type there is "Collectivism," by Emil Vandervelde, the eminent Belgian Socialist leader, a wonderful book. This and Engels' "Socialism Utopian and Scientific" will lead to books of a more advanced character, some of which we must mention. The four books mentioned in this paragraph cost fifty cents each, postpaid. They are well printed and neatly and durably bound in cloth. Going a little further, there are two admirable volumes by Antonio Labriola, expositions of the fundamental doctrine of Social philosophy, called the "Materialist Conception of History," and a volume by Austin Lewis, "The Rise of the American Proletarian," in which the theory is applied to a phase of American history. These books sell at a dollar each, and it would be very hard to find anything like the same value in book-making in any other publisher's catalogue. Only the co-operation of nearly 2000 Socialist men and women makes it possible. For the reader who has got so far, yet finds it impossible to undertake a study of the voluminous work of Marx, either for lack of leisure or, as often happens, lack of the necessary mental training and equipment, there are two splendid books, notable examples of the work which American Socialist writers are now putting out. While they will never entirely take the place of the great work of Marx, nevertheless, whoever has read them with care will have a comprehensive grasp of Marxism. They are: L.B. Boudin's "The Theoretical System of Karl Marx" and Ernest Untermann's "Marxian Economics." These also are published at a dollar a volume. Perhaps you know some man who declares that "There are no classes in America," who loudly boasts that we have no class struggles: just get a copy of A.M. Simon's "Class Struggles in America," with its startling array of historical references. It will convince him if it is possible to get an idea into his head. Or you want to get a good book to lend to your farmer friends who want to know how Socialism touches them: get another volume by Simons, called "The American Farmer." You will never regret it. Or perhaps you are troubled about the charge that Socialism and Anarchism are related. If so, get Plechanoff's "Anarchism and Socialism" and read it carefully. These three books are published at fifty cents each.
