The John Samuel Stamm Collection is comprised of two series. In the first series there are three typed manucript volumes which include lectures, Bible studies, and orientation messages delivered to Evangelical Seminary students in 1955. Other bound manuscript volumes include a commentary on I Thessalonians; an autobiobraphy; two volumes of sermons; letters of appreciation on the occasion of Stamm's retirement as well as a volume of Remembrances; and a history of the proceedings in the union of the Church of the United Brethren and the Evangelical Church. The second series is comprised of two scrapbooks containing clippings, articles, and expressions of appreciation at the time of his death.

Consists of manuscripts and clippings. Includes Commentary on the Discipline, from the Bishop S.C. Breyfogle Library. Bishop Breyfogel used this in the preparation of his Digest of Evangelical Church Law. There is also a journal/autobiography written by Yeakel between the years of 1853 to 1865. Another item of note is an oversized scrapbook full of clippings which reflect articles written by Yeakel, points of interest, and a history of "old-time Evangelical preaching."

The Cowden collection is a significant representation of family records and genealogy together with records of his work in developing the Sunday School work of the United Brethren Church. The materials regarding the Sunday School offer a window on the progress in developing the administrative and educational practices of the church. Cowden gave creative leadership in applying the Chautauqua format to the work of the Sunday School. The collection also includes Cowden's manuscript of his autobiography. It was published by the United Brethren Publishing House in 1915. Two items included are over-size and are packaged separately: a marked map of the Battle of Shiloh, and an architectural drawing of a tablet commemorating the life and work of Rev. John George Pfrimmerer, M.D., who established the first United Brethren Churches in Indiana and the first United Brethren Sunday School in 1820 on the site of this tablet.
