These songs, along with hundreds of others, were collected for an archive of lyrics by amateur Jewish authors in the Soviet Union during World War II and documented by a team of researchers from the Cabinet of Jewish Culture from the Ukrainian Academy of Sciences, which operated under the auspices of the Soviet government. They describe the Jewish wartime experience, telling tales not just of Holocaust survivors but of Jewish soldiers in the Red Army, women working in factories on the home front and Polish refugees building new lives in far-flung corners of the Soviet empire.
