Sunday School Periodicals, 1818-1885 The Sunday School Periodicals, 1818-1885 collection features a broad cross-section of Sunday school literature that was read in churches and at home.

The collection also contains training and preparation materials for teachers. Subjects covered in these publications include Bible and catechism lessons, music, and poetry from a broad range of religious groups across every region of the expanding nation. Church communities represented here include Baptist, Methodist, Episcopal, Presbyterian, United Brethren, Unitarian, Lutheran, Church of God, Mormon, and various Sunday School Unions.
