The American Army was a reading and thinking army and that one of the seven great big-brothering organizations which undertook to supply it with reading matter, the American Library Association, was kept busy. The Library War Service of the Association had in each of forty-eight large army and navy training camps and in seventy hospitals in the United States a central library building, or library quarters, with branches and stations radiating all over the camp or hospital area to render its volumes easy of access. It had collections of books in nearly two hundred hospitals and Red Cross Houses. It equipped with these collections over five hundred military camps and posts and aviation fields, schools and repair depots. It supplied with libraries 260 naval and marine stations and 750 vessels. It had nearly 2,000 branches and stations placed in Y. M. C. A. and K. of C. huts, barracks and mess halls. It shipped overseas 2,000,000 books and 64,000 magazines and distributed 5,000,000 magazines donated by the public through the mails. In its war service libraries there were over 5,000,000 volumes. Three hundred and forty trained librarians supervised its service. Accepted books to the number of 4,000,000 were given by the American people, who provided also the money with which were bought 1,300,000 more. Book donations were well sifted before the books were accepted for war service and the authorities of the association estimated that probably twice as many were given as were finally used. But even these enormous quantities of books and magazines were no more than sufficient to meet the desire for reading shown throughout the Army and the Navy. The Library War Service of the Association did its best to supply to every fighting man in the training camps at home, on the transports, on the cruisers and battleships, in the stations overseas, in the camps and rest billets, the book he needed when he wanted it, whether it was light fiction, or a technical treatise, or a work of history, economics, philosophy or travel. It supplied books in practically all the modern languages--about forty were represented in each of the large camps--for both study and reading and its lists were filled with titles of scientific, technical and other works that covered the whole range of modern knowledge and activity, philosophy, literature, history, biography, poetry, art, music, fiction, drama, economics, sociology, business, travel. There was demand for them all. Toward the end of the war and after the armistice the Library War Service bent its energies to meeting the greatly increased call for vocational books that would enable the fighting man to become more efficient in his special job or to get a better one when he should presently be returned to civil life.
