Two Washington University in St. Louis professors, Michele Boldrin and David Levine, have a new book about the current state of intellectual property entitled Against Intellectual Monopoly. You can purchase the book on Amazon and it is freely available online in PDF format (also here). There is a very positive review of the book (with more in depth analysis promised) available at the Ludwig von Mises Institute website. The authors are not socialists wanting to end property rights; these are strong free markets advocates who see current monopolistic protections for non-scarce resources as damaging to the free market competition of ideas. Jeffrey A. Tucker, the author of the review for the Mises Institute, even posits that Creative Commons is more akin to a free market solution than what currently exists as a result of government-instituted patent and copyright protections. Something to add to the reading list.
