The YIVO Library was looted by the Germans and the ERR, but an organization that called itself "The Paper Brigade" were able to smuggle out many books and preserve them from destruction. These materials were then saved from the Soviets by a Lithuanian librarian, Antanas Ulpis. These materials are now held in the Lithuanian Central State Archives and Martynas Mažvydas National Library of Lithuania. In 2014, with the cooperation of the government of the Republic of Lithuania Brent established the landmark Edward Blank YIVO Vilna Online Collections project at The YIVO Institute to preserve and digitize over 1.5 million documents and approximately 12,200 books representing 500 years of Jewish history in Eastern Europe and Russia.
