Which of F.A. Hayek's books should I read first?
I've only read The Constitution of Liberty, but I think you could read his works in chronological order. His actual economic work may be obsolete at this point. I would recommend reading more into his politics and social theory. His ideas about the distribution of knowledge in society are good too.
What do you want to know?
If you haven't, read:
