Library of Agudas Chassidei Chabad
During World War II, Rabbi Yosef Yitzchak was forced to flee from the USSR and went to Poland. He was given permission by the Soviet government to take many of his religious texts from his library with him. In March 1940, Rabbi Yosef Yitzchak managed to escape Europe for the United States, but was forced to leave his library behind. In the 1970s, many of the texts were recovered in Poland and were returned to Chabad. Today, the chief librarian is Rabbi Shalom Dovber Levine and contains over 250,000 books.
