Online Jewish encyclopaedia

Here's a new resource: The YIVO Encyclopedia of Jews in Eastern Europe. You can look up Janusz Korczak, fighter for children's rights who, when the Warsaw ghetto was liquidated, 'turned down an opportunity to escape and accompanied his charges to the Treblinka death camp'. You can look up Simon Dubnow, historian, about whom this story is told. Or Yitsḥak Katzenelson, Hebrew and Yiddish poet. You could read about the Lodz ghetto; about the Jews of Warsaw, the Warsaw ghetto and the Warsaw ghetto uprising. You could read about Chaim Rumkowski or Mordekhai Anielewicz - and much more.
