In the 1950s and 1960s, many publishers including Simon & Schuster turned toward educational publishing due to the baby boom market. Pocket Books focused on paperbacks for the educational market instead of textbooks and started the Washington Square Press imprint in 1959. By 1964 it had published over 200 titles and was expected to put out another 400 by the end of that year. Books published under the imprint included classic reprints such as "Lorna Doone", "Ivanhoe", "Tom Sawyer", "Huckleberry Finn", and "Robinson Crusoe".
