I ventured out to a local Barnes & Noble yesterday, and was pleasantly surprised that it was not only there, but also given some prominence on the shelf by the staff.
I think the book production folks at Que did a great job with the print edition. After spending so much time looking at drafts in Word, it was nice to see it, y'know, actually given form with typography and layout.
I had also forgotten -- honest! -- about the foreword I had written for the book. So I can say that not only did I help with the editing, but my writing does appear in it, even though it's but one page of 432.
I think by law I am required to link to where you can purchase it, in case you do not know how to exchange money for books, so go to it.
(I didn't notice Mazes for Programmers next to it until after I had gotten home, but what a book title!)
