    Letters from the Feb. 14, 2004, issue of Science News

    Revealing words “Bookish Math: Statistical tests are unraveling knotty literary mysteries” (SN: 12/20&27/03, p. 392: Bookish Math) skipped one of the most significant methods for analyzing text for authorship. On March 11, 1887, Thomas Corwin Mendenhall reported in Science a straightforward method of plotting word length versus frequency. The beauty of this method is that […]
