I saw today on the Mises Institute’s website that they made a great Rothbard work, Austrian Perspective on the History of Economic Thought, available in two volumes as free PDFs. Go to the article about the online release of this great work.
The Mises Institute is a wonderful resource for anyone who wants to learn about economics, specifically the Austrian School. They have the largest collection of books, journals, and essays on economics available as free PDFs available online. They also have hundreds of lectures, interviews, and audiobooks available for download.
I highly recommend their daily articles, which provide thought-provoking and intellectually stimulating ideas and commentary on subjects ranging from political commentary to economic theory and history. Warning: The Mises Institute can be very dangerous to lovers of big government, embracers of socialism, and those who despise freedom. Read at your own risk.
