Anatomy of the Auschwitz Death Camp, edited by Yisrael Gutman and Michael Berenbaum, is probably the most comprehensive volume on Auschwitz in print. Essays by leading scholars from Europe, Israel, and the United States document the history of the camp, the technology and magnitude of the genocide that occurred there, profiles of the inmates and the Nazis who ran the camp (such as Joseph Mengele), the underground resistance that arose, and what the outside world knew about Auschwitz and when. It"s not a book to read straight through because of the sheer volume of information (more than 600 pages of text) and the horror of its contents. But it"s the best resource for answering a wide variety of questions about the camp, especially those raised by the many excellent memoirs by the survivors. --Michael Joseph Gross
