Hm.  I see that the purging of "original research" from the "Characteristics" section (some of which I contributed) has resulted in the impression that Vance was mainly a mystery writer, who also wrote some SF and fantasy.

Way to go, folks.  If reporting facts about what's in the books is "original research," then I'm not sure why we have a list of the titles, since someone apparently had to "research" those.  Etc.
