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:"

https://www.amazon.com/Computer-Programming-Volumes-1-4B-Boxed/dp/0137935102

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.
