The United States Holocaust Memorial Museum (USHMM) has some tremendous online resources, and the recent addition of the Holocaust Encyclopedia continues in this tradition. The interactive Encyclopedia includes hundreds of articles that cover topics like the Third Reich, refugees, ghettos, and the liberation of Nazi camps. Each entry contains hypertext links to other entries and relevant resources, including timelines, photo galleries, and primary source documents. Visitors can use the "Browse Articles" to get started, and they should also note that the articles are available in French, Spanish, Italian, Russian, Turkish, Arabic, and six other languages. In the "Additional Resources" section, visitors will find a link to "The Holocaust: A Learning Site for Students" and a complete "A-Z" list of all the articles.
