Originally released in hardcover form by Yale University Press in 2008, the YIVO Online Encyclopedia of Jews in Eastern Europe covers 1,000 years of Jewish history in Eastern Europe, with more than 1,800 articles on every topic imaginable — from religion to literature, and from politics to popular culture. This encyclopedia seeks to reflect all aspects of Jewish life in its variety and multiplicity. The YIVO Encyclopedia is intended to be an ecumenical work: nondenominational, nonideological, and nonconfessional.
