Our clueless local Chapters (both of them) have recently bi-furcated "Fantasy" (meaning all the books that seem remotely like all the WotC game novels) and "Science Fiction" (meaning all the books that seem remotely like all the Halo and Star Trek licensed novels).

Quite often I find humour in the attempts of the shelvers to properly locate things. KJ Parker showing up in Sci Fi because the trilogy has the word "Engineer" in it. Butcher showing up in both Sci-Fi and Fantasy, but not duplicates (odd numbers in one, even in the other? who knows?).
