Sorry for leaving more than one book. Good introductory books to Austrian Economics would be: Lessons for the Young Economist, by Robert P. Murphy, Economics for Real People, by Gene Callahan, Economic Science and the Austrian Method, by Hoppe. On liberty, I would read, For a New Liberty, by Rothbard, Conceived in Liberty, by Rothbard, A Beautiful Anarchy, by Tucker, The Great Fiction, by Hoppe, The Market for Liberty, by the Tannehill’s, and I’ll stop there.
