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.

This collection contains materials relating to Clymer's life after his college days at Asbury. The earliest records are correspondence, addresses/sermons, and the graduate papers from the 1940's. Clymer's correspondence, the largest quantity of the record types in the collection, covers every year from 1942 through 1993, except for about ten years between the mid-1950's and 1967. Clymer's collection of addresses, sermons, and lectures is the next largest group of records, and dates from the early 1940's through the late 1980's. The collection also contains copies of some of Clymer's publications. The original accession contained copies of his books and books in which he was a contributor, as well as articles in widely circulated journals. These have been removed and transferred to the Methodist Library, Drew University, Madison, New Jersey. The collection also contains various clippings, programs, pamphlets, reports, and photographs.
