There's old saying that law school isn't set up to teach people the law. It's set up to teach people how to think like a lawyer. This won't make much sense to you if you're not a lawyer but, trust me, it does make sense to anyone who's gone through law school only to realize that they really didn't know much about the law. Given that the focus of law school has more to do with modes of thinking and less with the practical aspects of practicing, you'd expect that Social Security law wouldn't be taught much and you'd be right. However, some law schools do teach the subject. Professor Jon Dubin of Rutgers Law School was kind enough to send me a copy of a Social Security casebook that he and Frank Bloch, Emeritus Professor at Vanderbilt Law School, put together. Actually, this is at least the second edition of the book. It's quite good. I would recommend it to anyone learning Social Security law.
I have to say that looking at the price of the book brought home to me how long it's been since I was in law school. I think I remember casebooks being about $30-$40 back then but, of course, we were studying by whale oil lamps back then!
