Joe the Plumber and his favorite books

Joe reads economics:

The Theory of Money and Credit (Ludwig von Mises): "It brought
monetary theory into the mainstream of economic analysis. It is
important reading for these troubled times."

My theory is that someone in Ron Paul’s camp told him to say that.  Here is the full list of his favorite books.  Here is my source.  Here is an on-line version of TOMAC.  Scrolling through it a bit, it is more readable than my recollection and it remains one of the better 20th century books on monetary theory.
