Crafted over the course of four years by the research and production staff of the United States Holocaust Memorial Museum, the Historical Atlas of the Holocaust provides a unique depiction of Europe between 1933 and 1950. Compiled from archives around the world, the Atlas is based on extensive research into primary sources -- such as period maps captured from the German army, survivor testimony, and aerial photographs taken by American, British, and German forces -- illustrating the Nazi camp system that pervaded Europe.<P>The Museum's researchers have prepared detailed plans and explanatory text for more than 25 Nazi concentration, transit, forced-labor, and extermination camps. In addition to maps of major cities and ghettos, the Atlas charts the destruction of synagogues during Kristallnacht; the movement of Nazi killing squads across eastern Europe; the routes of deportations and forced marches; and the location of Nazi pseudo-scientific experimental facilities.<P>While the main focus is on the Holocaust of Eastern Jewry, the Atlas includes maps and text which document the Nazi persecution and murder of other groups, including the handicapped, Roma (gypsies), homosexuals, Poles, political opponents, and Jehovah's Witnesses.
