Has anyone seen my books?

Just a quickie: I can't find my copies of Only Begotten Daughter by James Morrow, Edgeworks 4 by Harlan Ellison, or The Stars, My Destination by Alfred Bester. Anyone know where they went?

Edit: I'm also missing my copy of Driving Blind by Ray Bradbury, and my Elric books, but I think I know where those went.
