Geoffrey Megargee on Nazi camps and ghettos

I watched an interview yesterday on Book TV with Geoffrey Megargee - author of Inside Hitler's High Command (2002) - about the set of reference volumes he and others have been working on for about a decade for the US Holocaust Memorial Museum, the Encyclopedia of Camps and Ghettos, 1933–1945, from which Volume I has recently been released. Here's the link to the brief (18-minute) interview.
