'Einhorn has written an important and well-judged book that casts intelligent and thorough economic analysis on some recent controversies in digital media copyright. . . Given the propensity of European copyright and Internet lawyers to profess an even greater ignorance of economics than they actually possess, this book should be required reading for lawyers who seek to engage with the central economic purpose of copyright law: to gauge the protection of monopoly for the author necessary to reward and therefore encourage innovation, while assessing the fair use that is just for the user. Einhorn's view is a reasonable and most careful explanation of these economic precepts, balancing his view from economics with regard for legal precedent and the economic education of jurists.'
