In 2005 the library at PTS was selected as the recipient of an alumnus' hymnody collection, comprised of over 1,100 titles, gifted by his widow, Mrs. Dagmar Merrick. The Rev. Daniel Merrick’s collection includes monographs, journals, and ephemera. Of particular note are his records from his tenure as the editor of the Chalice Hymnal for the Christian Church (Disciples of Christ). This resource is an invaluable addition to the Disciples research materials of the library. The collection is housed in the Charles W. and Helen L. Edwards Special Collections Room.
