WASHINGTON — A little more than a decade ago, researchers at the U.S. Holocaust Memorial Museum decided to create an encyclopedia of concentration camps. They assumed the finished work would be massive, featuring a staggering 5,000 to 7,000 camps and ghettos.
They underestimated by 15,000.
Their ultimate count of more than 20,000 camps is far more than most scholars had known existed and might reshape public understanding of the scope of the Holocaust itself.
“What’s going to happen is that the mental universe of how scholars operate is going to change,” said Steven Katz, director of Boston University’s Elie Wiesel Center for Judaic Studies. “Instead of thinking of main death camps, people are going to understand that this was a continent-wide phenomenon.”
