The collection consists of the scrap book of Alec Crosby, a lay worker at St. Mary's Mission, Ovamboland, from 1924-1931.

It includes manuscript notes, press clippings, photographs and printed reports, describing the early days of St. Mary's Mission in Ovamboland which was started by the Rev. George Tobias (later Bishop of Damaraland). Crosby was the brother-in-law of Tobias and worked as an agricultural and industrial instructor at the Mission.
