The book is available in e- and regular form from the University of Chicago Press, here. There are several other prior posts about the manuscript and related works here. His article on the dailybeast.com about how "law schools fudge the numbers" is here.
I must say that the book is a great read -- by that I don't mean it was enjoyable. I've had some grave doubts about this profession and law schools generally for a while, and most of what I read confirmed some of my suspicions. Some of what he observes is no doubt old news to many people -- that the bottom half of law students essentially subidize the education of the top half, since the top half gets more scholarship money (whatever the need) because LSAT points are what schools need in this age of US News; law professors make a lot of money for little work, relatively speaking (some of the salaries are in the $300,000 and up range, which I can tell you I don't come even close to making!); law schools are controlled by US News but also seek to control it by manipulating everything they can; law school tuition is unsustainable and the cost-benefit to many students is not in favor of attending; there are too many law schools graduating too many law students; the third year of law school is wasted and/or unnecessary; and so on.
I must have dog-eared every page, but have given it to my wife to read. I hightly recommend it. It's about 180 pages of text, and an easy 2 hour read.
