The Congregational Church Papers brings together records from a number of Southern California Congregational Church organizations. The earliest records include those of the Congregational Ministerial Union of Los Angeles and vicinity, 1908-1934; Woman's Home Missionary Union of Southern California, 1888-1925; and Woman's Board of Missions for the Pacific, 1889-1914. The greatest portion of the collection is annual reports and miscellaneous items from member churches of the Congregational Conference of Southern California and the Southwest, 1952-1963. Papers from women's organizations account for more than a third of the collection.
