The full text of the book is now on line, for free, right here. I intend to make copies available for Apple’s iBook store, Kindle, and short runs of hard copies, for a minimal price.

I am publishing this based on the Agile software development model – many iterations, publish new editions often. The text as it exists today is a snapshop of a fluid and changing work, and this model gives me room to change things more frequently and to publish new editions whenever I see fit.

I am eager for your comments and questions, my readers are my editors! Your thoughts and ideas are an integral part of this text, including all reasonable dissenting voices. If you are persuasive in your dissent, I may adapt the text of the book in response and it will shortly go into the next edition. If you are reading this, thank you!
