The Christian Literature Society (C.L.S.) is purely a religious one. The Society as it stands now, is an amalgamation of several societies which made their appearance as publishers and distributors of Christian literature in India. In 1818, the Madras Religious Tract Association was formed as an auxiliary of the London Religious Tract and Book Society imported tracts which were zealously distributed from the Association depository. The London Religious Tract Society itself originated in 1799 to promote the circulation of religious books and treatises in England and other countries.
