He does mention that he "...reach[es] for Introduction to Algorithms before Knuth's The Art of Computer Programming every time.", so it looks like TAOCP was intentionally omitted.
Yeah, I saw that. I commented on his site that I think CLRS and TAOCP are two very different types of books, and shouldn't be viewed as substitutes for each other.
Should be renamed "Five programming books I read once back in college but now only keep on the shelf to make sure that other CS geeks know how 'leet' I am."
