Jewish copyright law is a rich body of jurisprudence that developed in parallel with modern copyright laws and the book privileges that preceded them. Jewish copyright law owes its origins to a reprinting ban that the Rome rabbinic court issued for three books of Hebrew grammar in 1518. It continues to be applied today, notably in a rabbinic ruling outlawing pirated software, issued at Microsoft's request. In , Professor Netanel 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. He describes each dispute in its historical context and examines the rabbinic rulings that sought to resolve it. Remarkably, the rabbinic reprinting bans and copyright rulings address 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 key junctures, it fashions strikingly different answers to those key questions. The story of Jewish copyright law also intertwines with the history of the Jewish book trade and with steadfast efforts of rabbinic leaders to maintain their authority to regulate that trade in the face of the dramatic erosion of Jewish communal autonomy in the eighteenth and nineteenth centuries. This book will thus be of considerable interest to students of Jewish law and history, as well as copyright scholars and practitioners.
