An advertisement for books published by Emanuel and Marcet Haldeman-Julius, Girard, Kansas. The Little Blue Books were 3 ½ by 5-inch reprints of classical, educational, biographical, and other literature with heavy-paper covers. Originally the books were 25 cents each, but with mass advertising and greater volume, the price was reduced to a dime, later to a nickel. Haldeman-Julius devoted his life to crusading against "bigotry and bunk. prejudices and fanaticism." He believed that the life of the average American was harmed by political, economic, and religious restriction designed to promote inequality. One of his purposes for publishing the Little Blue Books was to inform people about things those in power did not want them to know--self-improvement, birth control, the hypocrisy of religion, and similar topics.
