In this collaborative volume, the editors examine the role of Judeo-languages in literary, social, religious, and cultural channels of knowledge transfer, particularly in the dissemination of oral and written traditions beyond the core intellectual elite to the secondary Jewish intelligentsia and broader audiences. This phenomenon is evident in Yiddish, Judeo-Spanish, Judeo-Arabic, Judeo-Italian, Judeo-French, and Judeo-Turkish from the Middle Ages to the 20th century. The studies in this book present a wide range of manuscripts and printed editions, highlighting the diverse functions and roles of Judeo-languages as vehicles for the distribution, transmission, and mediation of knowledge.
