Fuller, Eisenberg and Gergen's Basic Contract Law, 9th

First, you must consider that a) this is a law school casebook, it's not meant to be light reading, and b) my review might be somewhat tained by the fact that I've taken a Contracts course taught by Mel (an awesome lecturer), but: this is a more clearly organized and well edited casebook than most.The cases are well chosen and often paired in contrast to illustrate the few most common views courts have on a particular rule of Contract, usually with a full case first of the majority view and a few short "squib" cases after for emerging or fading perspectives. It's up to date with cases on electronic signatures and shrinkwrap licenses. The commentary after each section is readable and lucid. The organization is clear -- Eisenberg himself lectured straight through the book and it made for what seemed like a solid, complete course, focusing mostly on the full-length cases. If you're planning on teaching Contracts, I'd take a good look at Mel's book.

This book ia a little dry, but it has everything you have ever needed to know. It is written for people that are not lawyers but need to write contracts as a major part of their job. While asking a real lawyer may be necessary in some cases, in many situation this book will save you hundreds on legal fees
