A note about autographs: I do not send photos, so please don't ask. Unfortunately, I'm no longer able to have readers send me books to sign. If you give me your snailmail address, I'll gladly send you signed bookplates to put in whatever books you have. I realize that's not exactly the same, but it's the best I can do.
