I really liked "Common LISP: A Gentle Introduction to Symbolic Computation", from David S. Touretzky. I think it could have been mentioned. Unlike Practical Common Lisp, it has exercises and extensive sections in each chapter just on tools (such as dribble, trace, describe, step, et cetera).

Moreover, I was expecting to see "Paradigms of Artificial Intelligence Programming", from Peter Norvig. I have not fully read it, but it seems to be an awesome book. Not just to learn Lisp but a good book in general, since the code is beautifully designed. Despite the title, AI (GOFAI, actually) is just the domain, the lisp techniques and code approach can be applied to other areas.

This Reddit's post presents another list that might be an interesting complement to the one we are discussing here: https://www.reddit.com/r/Common_Lisp/comments/ddcoar/selecti...
