American Sunday-School Union
"The First Day Society," a society to reform the use of Sunday (and other days) by teaching from the Bible, began in 1790. Many Sunday-school societies were formed and the "Sunday and Adult School Union," changed its name to the "American Sunday school Union" in 1824. Their main job was to establish schools, but they became a very active publisher as well.
Policy of The American Sunday-School Union:
No books are published by the American Sunday-School Union without the sanction of the Committee of Publication, consisting of fourteen members, from the following denominations of Christians, viz. Baptist, Methodist, Congregationalist, Episcopal, Presbyterian, Lutheran and Reformed Dutch. Not more than three of the members can be of the same denomination, and no book can be published to which any member of the Committee shall object.
Interesting people involved in this work:
Edwin Wilbur Rice, The Sunday-School Movement, 1780–1917, and the American Sunday-School Union, 1817–1917. (Philadelphia: American Sunday School Union, 1917).
