My article Intellectual Property and Libertarianism was published last month in Liberty magazine (December 2009 issue). This article is based in part on a speech at Mises University 2009 (July 30, 2009; audio; video) and also on my What Libertarianism Is, which contains references not present in the Liberty paper (as does The Case Against IP: A Concise Guide). A version with endnotes was published here in Mises Daily.
