I am currently reading the lengthy history of the Nazi concentration camps (Konzentrationslager), by Nikolaus Wachsmann. I’ve only just started it. It’s heavily footnoted, with over 600 pages of text, then another 200+ pages of appendixes, footnotes, and index. I already knew about the early beginnings of Dachau from another book I read, but I wasn’t aware that there were 27 main camps, and over 1,100 attached satellite camps established by the SS, over the course of the Third Reich.
