Funny, I was just going through Amazon and some other websites and making a list of books I need to get in the future. My current top 10 to buy list looks like this:
1)America's Great Depression - Rothbard
2)Free to Choose - Friedman
3)The Death and Life of Great American Cities - Jacobs (supposed to be really interesting if you like cities and want to know how gov't planning turned them into the slums a lot of them are now)
4)Ethnic America: A History - Sowell
5)Conscience of a Conservative - Goldwater
6)The Betrayal of the American Right - Rothbard
7)The Way the World Works - Wanniski
8)The Law - Bastiat
9)God and Man at Yale - Buckley
10)The Theory of Money and Credit - Mises
Other Books I highly recommend:
-Economics in One Lesson - Hazlitt (Just finished reading. This is one of the greatest, simplest explanation of how economics works I've ever read. I would strongly encourage everyone to read this.)
-The Road to Serfdom - Hayek
