The following index has been designed to help the reader locate specific types of wordplay published in 26 issues of Word Ways from February 1978 through May 1984; it updates a similar index for 40 issues of Word Ways from February 1968 through November 1977 appearing in the February 1978 issue. Both indices use the same format: a logological core consisting of (1) letter-patterns in words, (2) operations upon letters in words, and (3) relationships between letters and sounds, and a periphery (the intersection of logology with other branches of wordplay) consisting of (1) literary wordplay and games, (2) academic language studies, and (3) word games and puzzles. Wordplay involving special sets of words (presidents, statenames, -cide words, etc.) is separately indexed.
