Times are exciting. Our book, Real World Haskell, is now available in a number of venues. But before I get to that, I’ve got to talk about what a thrill this project has been.

I created our internal Darcs repository in May, 2007. Since then, the three of us has made 1324 commits — and that doesn’t count work done by copyeditors and others at O’Reilly.

We made available early drafts of the book online for commenting, which served as our tech review process. By the time we finished writing the book, about 800 people had submitted over 7,500 comments. I’ve never seen anything like it, and really appreciate all those that commented about it.

As for availability, RWH is available:

For immediate purchase with electronic delivery, from O’Reilly’s page

For immediate viewing on Safari Books Online, at its book page

Paper editing timing is still tentative, but we’re estimating arrival in bookstores the week of December 8.

People are talking about it on blogs, twitter, etc. We’re excited!
