I wouldn't recommend wasting your time with Ron Paul's book. Now, I'm not defending the Fed, but his arguments aren't much more than invective, polemic, and empty, idealistic rhetoric.
You might be better off reading: The Historical Performance of the Federal Reserve: The Importance of Rules. Mankiw's textbook on economics has a nice explanation as well.
> The Historical Performance of the Federal Reserve:
Um. Close to 650 pages?!!
Not saying it's not worth it. But Paul's book is a much easier start. If you want someone to run an ultra-marathon, first start with getting them to finish a 5k.
