Thanks for the pointer, Tim. Several of those look very interesting and I'll be ordering.
While we're on this topic, I would be remiss to not remark that Prof. Don Knuth has published Volumes 4A and 4B of his "The Art of Computer Programming:"
That's the complete set, which includes the classic volumes 1 to 3. This would be the set to buy for people who are just starting out in computer science.
