Devoted to late nineteenth century adventure novels? Irredeemably neurotic? For you, there is Philip Jose Farmer's Wold Newton universe, in which such extraordinary gentlemen as Dracula and Sherlock Holmes are related through complex genealogies dating back to a peculiar meteorological event in the British countryside. This is meta-nerdiness.
The prolific and inventive Philip Jose Farmer has long been one of my favorite science fiction writers, but he is rarely counted among the Lists of Greats of the 'old school' authors.(Asimov, Clarke, Niven et al). Does anyone else have a favorite SF writer who seems to get less credit than he or she deserves?
