Part of a multi-volume collection of over 450 primary source documents relating to Mormon origins in Vermont, New Hampshire, New York, and Pennsylvania. As such, it is essentially a documentary history of the Joseph Smith, Sr., family and the infant Church of Christ (later The Church of Jesus Christ of Latter-day Saints), beginning with the early lives of Joseph Smith Sr. and Lucy Mack Smith and ending with Joseph Smith Jr.'s move to Ohio in January 1831 and removal of most of the church later that spring.
