Here's my two cents (more like a buck fifty actually)
How to Get Into the Top Law Schools: Found this MINIMALLY helpful at best. The guy had a lot of things in there that I simply don't agree with or have seen mounds of evidence to the contrary (sorry, can't recall any specifics as I read this early September). Also, I feel like a good chunk of the book was copied-pasted from his other How to Get Into the Top Business Schools book. There were a few places that even said "business school" where it was obviously supposed to be "law school." That really pissed me off. It was hard to take much of what he had to say seriously after that. Plus, I can't describe why, but the dude just looked like a total a-hole.
One L More of an entertaining read, and from what I've heard, an extreme case of how bad first year can be. It was an easy read and I reccomend this to everyone.
Law School For Dummies Despite the ironic title I found this to be a pretty good buy. Has a lot of info, covering studying for the LSAT all the way to looking for a job. A great place to start for the clueless (like me) and is also very recent (I think the author graduated in '03 or '04).
Princeton Review's The Top 159 Law Schools: This is not worth buying, but definitely worth checking out for anyone still deciding between schools. It was just put out this year and each two-page profile of the school is based primarily on student surveys. Definitely head over to Barnes 'n Noble and glance at your school, very informative.
That's all folks.
