I just wanted to make this resource known to the SN community.
Tom Woods is an accomplished academic historian and best selling author. He has written about a dozen regular print books on American history, Catholicism, and Economics (perhaps other topics too).
This site contains the numerous shorter e-books that Tom has been writing over the past decade or so. They tend to be more topical, but all are recent enough that the content is still relevant. Tom is a libertarian in the Austrian tradition and a great articulator of that perspective.
