Book excerpt: This source edition on the persecution and murder of the European Jews by Nazi Germany presents in a total of 16 volumes a thematically comprehensive selection of documents on the Holocaust. The work illustrates the contemporary contexts, the dynamics, and the intermediate stages of the political and social processes that led to this unprecedented mass crime. It can be used by teachers, researchers, students, and all other interested parties. The edition comprises authentic testimony by persecutors, victims, and onlookers. These testimonies are furnished with academic annotations and the vast majority of them are published here for the first time in English. Volume 3 documents the persecution of the Jews in the German Reich after the start of the Second World War and in the ‘Protectorate of Bohemia and Moravia’, created in March 1939, until September 1941. It reveals the increasing isolation of the German and Czechoslovak Jews but also the perpetrators’ plans up to the eve of systematic deportations.
