Looking back to the not-so-distant late 1980s, it is hard to believe that most of the academic instructors teaching courses on the Holocaust at American universities could have fit into a single small room, as was the case during the meetings of the committee overseeing the content of the permanent exhibition then being planned at the United States Holocaust Memorial Museum (USHMM) in Washington, D.C. In academic circles, a debate was still raging over whether the study of the Holocaust should even be treated as a separate field of research. And if so, should it be part of German history or so-called Jewish studies? At that time, many original documents and photographs lay undiscovered in archives, and authentic photographs related to the Holocaust were mixed in with footage from postwar films about the war and the Holocaust. There were few scholars researching this topic. In the United States, as elsewhere, the past two decades have seen a veritable revolution in the accessibility and reliability of knowledge about the Holocaust.
