The other reviews say it all....just a once in a life time book. Got it through the Military Book Club on one of their sales and could not be happier. Whether you use it for reference or, in my case, sitting down to read this detailed, long book, it is almost everything you ever wanted to know about the SS. Already from this book I've seen that Himmeler's SS was more rooted in German fantasy that I supposed. Good explanation too, especially the runic symbols SS. They just were not symbols but stood for something more meaningful.
Very enlightening beyond other books I have, combined with last summer's purchase of the new biography Heinrich Himmler (Peter Longerich) by me from Amazon, I have quite a detailed study ahead of me.
No mistake, this book will make some WWII readers very happy. It's cost will certainly repay itself with year's of reading and reference.
