From 1940 to 1943, an underground group called Oyneg Shabes existed in the Warsaw Ghetto. The group members contrasted the methodical extermination of Jews with their work as historians and archivists, setting out to collect and preserve both evidence of the vast, diverse Jewish culture of Eastern Europe, and evidence of its destruction. Eyewitness accounts and photographs, chronicles and diaries, prose and poetry, drawings, sermons and anecdotes, creative evening programs and exchange rates, tram tickets and candy wrappers, restaurant menus and food cards collected over three years were carefully packed and hidden in three hiding places. After the war, only two of them were discovered. Work on deciphering the unique archive continued for several decades, the publication of 36 volumes was completed in 2018. The collection, compiled by Professor David G. Roskies, includes works and documents telling about the Holocaust in the voices of its first researchers - the victims themselves - “in the first person, in real time, in spite of time and for all times.” The publishing layout is saved in PDF A4 format.
