My first contributions to Word Ways were on word ladders and networks. In "Word Network Spans in the OSPD" in Feb 1989, I analyzed 4-letter, 5-letter and 6-letter word lists; in "More Network SPans in the OSPD" in AUgust 1990 I briefly studied 7-letter and 8-letter words. This was the limit of my computer capabilities at the time. Since then I have doubled the side of my lists, mostly with Webster's Second words, but I have also upgraded my computer and DOS. Here is a new study of 8-letter and 9-letter words. Part of my objective was to find ideal ladders: ladders in which all eight letters of a word change in eight steps. One ideal ladder was known in 1990; may additional ones are identified below.
