Langbein, himself a key member of Combat Group Auschwitz, uses all the rigour and objectivity we expect of the serious historian. The book is an important contribution in these days when those who survived to bear witness are fewer and where the accounts by important witnesses such as Filip Muller, Hans Marsalek and Eugen Kogon, are out of print.
This book is especially important as evidence to counter the Holocaust denialists, and those who condemned Jewish and other people for "acting like sheep".
