In order to understand the limits of recreational linguistics, and in order to identify unsuspected possibilities for research, it is often desirable to map parts of the territory. This was the purpose of "The Word Surgeon's Compendium" in the August 1976 issue and "Words Within Words" in the May 1978 one, and this is the purpose of the present article. In contrast, the ten-year topical index in February 1978 was a global map of wordplay, containing no descriptive detail to justify the taxonomy used.
