Books by number in genre (this, by the way, is just the books that were on the shelves, i.e. maybe a fifth of my collection):
Manga - 2
Unknown (defy genre) - 5
RL (fiction about the real world) - 6
Mystery - 10
Media tie-ins - 10
Historical fiction - 11
Classics - 13
Science fiction - 21
Nonfiction - 42
Fantasy - 77
Oh yeah. Random other info: I have no stand-alone manga or mystery books, only one stand-alone scifi book (Shade's Children), and six stand-alone fantasy books - of which two are Diana Wynne Jones books and two are short story collections (the other two are Good Omens and Ella Enchanted).
