This is the web page for my book Common Lisp Recipes (ISBN 978-1-4842-1177-9). Previews are, for example, available via Amazon or Google Books. The book is also available via Springer Link, so if you are a student, you might be able to read it for free from within you university's network.
Errata and Addenda can be found here. If you find any errors in the book which aren't already listed there, please email me.
The code from the book is here. Note that this is not code that's meant to be actually used. Some of it is even defective or inefficient on purpose. These are just fragments intended to save you some typing if you want to follow the book's text.
Franz Inc. have set up a page explaining how to use the code examples with Allegro CL. (You can, of course, also use other Lisps like Clozure CL, SBCL, or LispWorks.)
In case you like the book (or if you just want to do me a favor), recommend it to your friends. Or write an Amazon review. Or blog about it. Or tweet about it. Or link to this page. That'd be nice!
Here are some links to order the book online:
(Or, even better, support your local bookstore, if you still have one.)
If you're completely new to Common Lisp, you might also want to check out Peter Seibel's Practical Common Lisp.
