This book is based on the conference "Photographs from the Camps of the Nazi Regime," which took place in November 2016 at the Center for Jewish Studies in Graz. Historically, photography has become one of the key media for researching the Holocaust, due to the extensive and diverse photography that occurred in concentration camps—despite all official prohibitions. The thematic range of the contributions published here spans from the private snapshot photographers among the SS to the photographs taken by the identification service, as well as the clandestine recordings made by concentration camp inmates. It presents rarely published photographic sources from the archives of Western and Eastern Europe, as well as the USA.
