-@emph{Paradigms Of Artificial Intelligence
-Programming}, by Peter Norvig, also has some good information on
-general Common Lisp programming, and many nontrivial examples.
-Whether or not your work is AI, it's a very good book to look at.

-Neither of the books above emphasizes CLOS, but @emph{Object-Oriented
-Programming In Common Lisp} by Sonya Keene does. Even if you're very
-knowledgeable about object oriented programming in the abstract, it's
-worth looking at this book if you want to do any OO in Common
-Lisp. Some abstractions in CLOS (especially multiple dispatch) go
-beyond anything you'll see in most OO systems, and there are a number
-of lesser differences as well. This book tends to help with the
-culture shock.
