By World War I, the "Social Register" had expanded into a multi-volume annual which included listings of Society members in 26 U.S. cities. Following Keller's death in 1924, the "Social Register" passed to several of his heirs. In 1926, a single city edition cost $6.00 and the full set of American editions cost $50.00; this when many Americans were still making do on a few dollars a day.
