I recently came across a web page listing libertarian books in order of their rating on Amazon.com; my Machinery of Freedom was number 70, not surprising given its Amazon rating.
The book is also available as a free pdf from my web page, so I checked the download statistics and was pleasantly surprised to find that it is being downloaded at a rate of almost two thousand downloads a month, plus about 300 more of the .prc (ebook) version. That got me curious—what would the list look like if it was restricted to books available as free downloads, ordered by the rate at which they were downloaded?
The Mises site has a lot of libertarian books on it. Are there any of my readers who are connected with that site and willing to report download rates, or who know of public information on the subject?
