Day Missions Collection, Yale University Divinity School Library. Microfilm. Evanston, IL: American Theological Library Association. (202 reels; 1285 titles)
The collection was begun by Professor George Edward Day at Yale in 1891, and named for him after his death. Professor Day envisioned a Library of Foreign Missions containing six types of material: the history of missions in various countries, missionary biography, the annual reports of missionary societies, periodicals, works prepared by missionaries for the use of the peoples of mission fields, and literature relating to Jewish missions. These titles constitute approximately one fourth of the Day Missions Collections. Criteria for microfilming were 1) subject area, 2) date of publication, and 3) physical condition. Selected were documentation of mission work in Asia and Oceania, published between 1800 and 1920, not previously filmed but showing physical deterioration.
