This trilogy is on my list of books to read someday...but I keep forgetting all about them. Never had any luck finding them in a used book store.
Foundations is a definite must-read set-or re-read, since I think it's been about 15 years. Just curious-did you bother with I, Robot the movie? COuldn't bring myself to. And I have to say, I prefer Asimov's Black Widows Club (that doesn't sound quite right-is it Black Widower's Club?) mystery short stories, and the Azazel ones. Just a personal quirk.
