Interesting article on Wikipedia by computer science and logic luminary Carl Hewitt. He's a smart guy, even if I think the article is not completely correct.
A printed copy of the book is also available! Awesome!
Well, Wikipedia's not really doing it, but it's nice that this project is getting some visability.
