"Practical Common Lisp", by Peter Seibel - hardcover book on programming in Common Lisp

This book attempts to teach its reader the Lisp programming language -- specifically, the "Common Lisp" dialect. More info is available on Amazon: http://www.amazon.com/Practical-Common-Lisp-Peter-Seibel/dp/1590592395

To give you a fair warning, the full text of the book is available online (http://gigamonkeys.com/book/). But sometimes there's nothing like reading from an old-fashioned, physical book. :)
