The Common Lisp Cookbook
For a more modern and up to date guide, Edi Weitz&#x27;s &quot;Common Lisp Recipes&quot; is a great reference: <a href="https:&#x2F;&#x2F;www.amazon.com&#x2F;Common-Lisp-Recipes-Problem-Solution-Approach-ebook&#x2F;dp&#x2F;B01JFTONBS&#x2F;ref=mt_kindle?_encoding=UTF8&amp;me=" rel="nofollow">https:&#x2F;&#x2F;www.amazon.com&#x2F;Common-Lisp-Recipes-Problem-Solution-...</a><p>The more I use Common Lisp, the more disappointed I am that it hasn&#x27;t become more popular.
