What are your favorite libertarian books?

As a small fundraising activity, LPSF has decided to be a part of
Amazon.com's associate program by listing recommended libertarian reading
material on our LPSF.org website, with links to purchase those books at
Amazon. Our share of the purchase will not be a huge amount (between 2 and
15 percent), but it's income without much effort. (If anyone knows of
similar programs with other retailers, please let me know the details.)

So, what are your favorite libertarian books? You can share these with the
entire list, or you can send them directly to me at vice-chair@...
