Eydes - Evidence of Yiddish Documented in European Societies

EYDES is an online version of the Language and Culture Atlas of Ashkenazic Jewry (LCAAJ):

"It is one of the biggest collection of spoken language in the world – about 6000 hours of tape recording. The archive was initiated and gathered by the eminent linguist and Yiddish scholar Uriel Weinreich. From the late fifties through the sixties he and his team interviewed emigrant informants, mostly in the US and in Israel. Most of the informants were survivors of the Holocaust and all of them were native to one of 600 selected cities and towns in Central Europe. The archive is an attempt at reconstructing the historical Yiddish language and culture area after it was dislocated and its home territory destroyed. The archive provides a basis for Yiddish and interlingual study and is a resource for anthropological cultural and historical research. At the heart of the inquiry, and thus of each interview, was a questionnaire designed on structural principles to cover the main topics of the linguistic and ethnological variety in the former Yiddish home territory.
