Book Wrap Up

Dear reader, I hope that you have found this book useful and fun to read. Please be advised that this book is not “done” in the traditional sense: On average, I update my LeanPub books four or five times the first year after publication, and less often after one year. I have updated my Common Lisp book over thirty times with new material since I published it a decade ago. My message to you is this: if you are reading this book for free online, please revisit the book link periodically for new material. If you bought this book and asked for notifications of new versions, then you will receive an email whenever I produce a new edition with a free download link.

Best regards,

Mark Watson
