About LL.M textbooks  

Hello, every myLot American friend. I hold great interests in law, and am planning to further study in a law school for LL.M, but before I enter a law school, I'd like to study myself first. But here's the problem, I need an entire LL.M general textbook list, from no matter which law school. No one I can turn to in this problem in the reality life, and I can find nothing from the Internet, too. If anyone who could offers a hand, I would be really appreciate it. Thanks.
