This collection contains sermons, notes, news clippings, articles, speeches, and photographs which document the ministerial career of I. F. Bergstresser. The bulk of this collection is comprised of sermons. A few sermons are in German. Articles Bergstressed used in preparing the sermons are included. Topics in his sermons include temperance, patriotism, Labor Day, Easter, Thanksgiving, Rally Days, Sunday School, and missions. In addition, there are several funeral sermons including those given on the deaths of Matilda A. Yeager, Lewis D. Krause, Louise E. Wentz, and Mrs. Wesley Bowman. Some of the addresses Bergstresser gave while he was a minister are included in this collection. Other items in this collection are mission materials (including two booklets by Walter Haller), a book on the first commemorative historical marker in the Evangelical Church, religious tracts, and a pastor's funeral book. There are also several large black and white panoramic photographs of conference meetings and conventions held in the Evangelical Church.

Record types within this collection include sermons, addresses, clippings, notes, note cards, orders of worship, and program materials. Most of the collection consists of sermons and addresses delivered by Arnold to a wide variety of community and church groups. These are mostly handwritten and in outline form, although a few are complete typewritten manuscripts. Topics include Biblical themes, challenges of Christian living, national and patriotic subjects, liturgical and secular holidays, and Sunday School lessons. Many were delivered to church services and church groups in Ohio and neighboring states; others were addressed to a wide variety of community groups. Among the organizations that benefited from Reverend Arnold's wit were the Ohio Farm Bureau, 4-H Club, Rotary Club, General Conference of 1933, and the Otterbein Guild. The clippings and notes are closely related to Arnold's sermons and addresses. Also included in this collection are some program materials relating to Arnold's work with the Evangelical United Brethren Sunday school publications, as well as a few orders of worship from his ministerial and speaking career.
