This microfilm collection contains The first fifty-one years of the Union Signal, the official newspaper of the Woman's Christian Temperance Union.

The Union Signal issues are Series XXI of a twenty-one-series microfilming project done between 1975 and 1977 with the cooperation of three repositories holding significant papers relating to temperance and prohibition: the Michigan Historical Collections (Ann Arbor), the Ohio Historical Society (Columbus), and the Woman's Christian Temperance Union (Evanston, Illinois). The project resulted in 426 reels of microfilm, of which the Billy Graham Center Archives purchased 198. See also collections 64, 65, and 66, other series in the Papers.

The papers for this collection and their provenance are described in detail in the Guide to the Microfilm Edition of Temperance and Prohibition Papers (Ann Arbor, MI: The University of Michigan, 1977), pages 239-320.
