Hi, I don't know who suggested that alternate history novels shouldn't be put in the science fiction category. I can understand why the sender might think this; however, I'd say the alternate probability universe story's primary duty is to deal with the "what-if" question; i.e., what if the south had won the Civil War. Or what if society were split along gender lines after a disaster? What would the societies be like and how would men and women react? There was a series of books by Suzy McKee Charnas which dealt with this as well as Sherri Tepper's book The Gate to Women's Country. And where would you put Octavia E. Butler's Patternist series? You have apparently human entities that live for thousands of years before life-stretching medical technology or nanotech possited by authors. So I would say that sf does deal with extrapolated reality based on possible or impossible future or present-day tech, it doesn't always perform in that way. Robert Sawyer's Hominid series deals with revival of what were Neanderthal humans which we can't do now. Although I grant you that Alternate Probability Universe stories may sound fantastic if you think there's such a thing as a multiverse and if one could actually do a kind of time travel, I wouldn't class this as fantasy because there is the possibility of a technology which may allow for that. Where would you place H. G. Wells' Time Machine? Would you call that sf or fantasy? I think of it as a kind of morality tale in the sf category because Wells is imagining what a far future society would be like given the society of his day. Harry Turtledove has stories where humans encounter saber-toothed tigers and hominids which they call sims. To me, this is alternate probability stories in the science fiction category. If you see something like The Case of the Toxic Spell Dump by the same author, that's definitely fantasy because the protagonist is living in a magic-works universe. Besides, what do you make of Arthor C. Clarke's remark that future technology would appear to be like magic to people in the past? Where would you place Gene Wolfe's series Book of the New Sun and Book of the Long Sun? Regards, Kim Friedman.
