Development of an updated version of The Jewish Encyclopedia in Russian (JER) on the Internet. The JER represents a mammoth 25-year effort, recently completed by the Society for Research on Jewish Communities, to produce an 11-volume Jewish encyclopedia for the Russian-speaking public. AVI CHAI funded a two-year initiative to update and produce an on-line version of the encyclopedia. The Society’s vision is to preserve the Encyclopedia as the most authoritative Russian-language source on Jewish studies, the history of the Jewish people, and the State of Israel. The website went online in the summer of 2005 and now attracts about 140,000 visits per month. AVI CHAI continues to fund efforts to keep the site updated and relevant.
