Along with Germany, Poland is the country talked about most in the testimonies of the USC Shoah Foundation's Visual History Archive. While over 15,000 interviewees were born there, a total of some 24,600 interviewees discuss Poland in the prewar, wartime, and postwar periods. These interviews are in several languages, including English, Hebrew, Polish, Russian, Spanish, Ukrainian, and Yiddish.
