TAN Books was founded in 1967 to keep books that taught the traditional Catholic faith in print. Over the next 40 years, TAN published hundreds of new and classic titles on theology, Scripture, Church history, traditional devotions (including St. Louis de Montfort’s Secret of the Rosary, which was printed in more than 4 million copies), and the lives of saints, many of which were reprints of titles from noteworthy American Catholic publishers such as Benziger Brothers and B. Herder Book Company. A number of original works were also published by TAN defending the teachings of the Catholic Church regarding contemporary social issues, such as abortion, compulsory sex education, and Freemasonry.
