This volume opens the world of Old Yiddish to scholars and students of Yiddish and Jewish Studies alike. It is a further step to broaden awareness that Yiddish, far from starting with the nineteenth century, can claim a history of over a thousand years. Presenting topics such as the oldest traces of Yiddish, bibliographical issues, language interaction, inter--pretation, contextualization and research history, this vol-ume will contribute greatly to understanding of Western Yiddish literature. Uniting renowned and emerging scholars from various disciplines such as philology, history, literary criticism, comparative literature, bibliographical studies, and musicology, Worlds of Old Yiddish Literature makes Old Yiddish Studies the focus of interdisciplinary dialogue within and between its chapters. The editors are Simon Neuberg of Trier University and Diana Matut of the University Halle-Wittenberg.
