Abstract: Records, mainly 1950-1962, of the American Council of Christian Laymen (ACCL), a national conservative organization (1949-1964) based in Madison, Wisconsin, that published and distributed literature concerning communist influence within American Protestant churches (especially within the National Council of Churches) and (after 1953) communist propaganda in school textbooks. The bulk of the collection consists of the extensive correspondence of its founder and president Verne P. Kaub. Prominent correspondents include William F. Buckley, James J. Kilpatrick, Joseph R. McCarthy, and many other conservative leaders. Also included are an incomplete run of “Challenge,” the ACCL newsletter; a copy of Kaub's book, Communist-Socialist Propaganda in Our Schools; and other records.
