Although Jews lacked a political locus standi for a communication system in the Middle Ages and Early Modern periods, their involvement in trade and the close relations among Jewish communities fostered the development of effective channels of communication. This process responded primarily to security and socio-economic considerations but it has important implications for the development of communication systems as well. Written by some of the most outstanding researchers in the field of Jewish history, this collection offers a rich and consistent picture of the main developments in communications in the Jewish world before the era of mass-media. This pioneering research reconsiders the principal means of communication among the Jewish communities in the Islamic world, Christian Europe, the Ottoman Empire, and the New World, from the seventh until the nineteenth centuries.
