The Jewish Encyclopedia was an encyclopedia originally published between 1901 and 1906 by Funk and Wagnalls. It contained over 15,000 articles in 12 volumes on the history and then-current state of Judaism and the Jews as of 1901. It is now a public domain resource, and many of its articles are available on the web.
Although an English language work, the vast majority of the encyclopedia's contemporary sources were German language, as this was the lingua franca of scholarship in the period. Of the works cited which are not German — usually the more classical works — the large part are either Hebrew or Arabic. The only heavily cited English-language source of contemporary scholarship was the Jewish Quarterly Review. It is widely regarded as "a remarkable piece of Jewish scholarship", superior to many subsequent works.
