Martis, Kenneth C. and Ruth Anderson Rowles (eds.). The Historical Atlas of United States Congressional Districts: 1789 - 1983. New York: The Free Press, 1982. xii + 302pp. (Book Review)
The history of this massive volume dates to 1936 when it was initiated as a long-range WPA project. After a desultory beginning, it was eventually abandoned and the files housed at Columbia University. Professor Martis inherited the task when circumstances again required transferral of the records to the University of Michigan. In essence, it consists of numerous maps depicting yea-and-nay roll call votes in both houses of Congress, much expanded and updated from its antecedents in The Atlas of Congressional Roll Calls published in 1943.
