From Maimonides to Microsoft traces the historical development of Jewish copyright law by comparing rabbinic reprinting bans with secular and papal book privileges and by relaying the stories of dramatic disputes among publishers of books of Jewish learning and liturgy. Professor Netanel describes each dispute in its historical context and examines the rabbinic rulings that sought to resolve it. Remarkably, the rabbinic reprinting bans and copyright rulingsaddress some of the same issues that animate copyright jurisprudence today: Is copyright a property right or just a right to receive fair compensation? How long should copyrights last? What purposes does copyright serve? While Jewish copyright law has borrowed from its secular law counterpart at keyjunctures, it fashions strikingly different answers to those key questions.
