The list is here.

I’ve read, um, twelve of them. I’ve never completely read 1984, never read Cryptonomicon, am sorely lacking on Philip K. Dick (although I have the feeling that they’re all similar), missed Pratchett, and have never heard of numbers 14, 19, and 20.

Huh. I would have thought that I was more of a geek than that, but it makes sense–I’m more Golden and Silver Age Scifi.
