And there were about 200 more ghettos than previously believed, said Martin Dean, editor of the recently published "Encyclopedia of Camps and Ghettos, 1933-1945, Volume II." It’s part of a long-term effort to document every site of organized Nazi persecution, beyond the well-known Warsaw ghetto and extermination camps like Auschwitz.
It "gives us information about ghettos that would slip into historical oblivion and be forgotten forever if we didn’t have this volume," Holocaust scholar Lawrence Langer said. "Who knew there were more than 1,000 ghettos?"
More Jews died during World War II in Poland and the western Soviet Union — today’s Ukraine, Belarus and Lithuania — than the estimated 1 million gassed in Auschwitz, Langer said.
