A New Way to Trace the History of Sci-Fi's Made-Up Words

One thing nerds like to argue about is what nerds are allowed to argue about. If you agree to stipulate that science fiction is often one of those things--and, hey, we could argue about that--then a problem to solve is the boundaries of that genre, the what-it-is and what-it-isn't. Finding the edges of science fiction is like taking a walk around a hypercube in zero-gee; you keep bumping into walls and falling into other dimensions. Reasonable people don't even agree on when it started-- Frankenstein? A story where a ghost kills people is horror; what if a robot did it?
