The A.H. Unruh fonds reflects Unruh's life as a preacher, teacher, and writer. It consists of sermons, some typed, many handwritten in the Gothic script. Most of Unruh's sermons are undated but his later sermons are recognizable by larger writing because his eye-sight was failing. Some sermons are in published form, cut out from various periodicals, many from The Voice, the MBBC periodical. In the fonds are Unruh's lecture notes from his teaching career at Pniel Bible School and at Mennonite Brethren Bible College. Records that document his writing are early Bible School textbooks, pamphlets, many articles, and his manuscript of Die Geschichte der Mennoniten-Bruedergemeinde. The book itself is in the J.A. Toews library. The CMBS audio-collection holds 46 casette tapes and 7 reel to reel tapes of Unruh's sermons. Also included are tapes of special occasions such as ordinations, the Unruhs' Golden Anniversary, and wedding sermons, and Unruh's funeral. Some of the records in this fonds are dated after Unruh's death because A.A. Unruh (son) seems to have added to the collection.
