The 7th, CTM, is a successor to SICP. It is a classic of modern times.

I've heard of the third one, Concrete Mathematics.

I vaguely remember reading of the 4th, HOPL 2, and the 5th, Computer Organisation and Design. As far as I recall, they are good actually.

I actually own Concrete Mathematics. Though I haven't read through it very seriously, what I have read has been excellent. (It was a great companion book for my Discrete Math course, whose book wasn't very good. (Discrete Mathematics and its Applications))

I might have heard of CTM before, but that's about it from this list.

I hated using the Rosen book in undergrad. Concrete Mathematics would have been fine as the sole text for such a course.

The great thing about Concrete Mathematics is that you can use it for what it is: a really cool "grab bag" of techniques.

Concrete Mathematics is fun. (You might also like _Mathematics: From the Birth of Numbers_. And http://projecteuler.net !)

The HOPL book has a big paper about the history of Lisp and dozens of pages of Chuck Moore, Icon, and Prolog AI chatting in French. What more do you need? (Also: Smalltalk. C.)

CTM is the best thing ever.
