Columbia University was one of the first institutions in the United States with a Yiddish program, and its Language and Culture Atlas of Ashkenazic Jewry is still a critical resource in the study of the many variants of the Yiddish Language. In honor of the digitization of the LCAAJ fieldnotes, Columbia University Libraries mounted an exhibition highlighting Yiddish at Columbia - both the vibrant academic research in the area as well as the deep and extensive collections.
