This work is an incredible help in tracking down resources concerning the Russo-German War (1941-45). Not only do Muller and Ueberschar list thousands of works in English, German, and Russian, but they walk the reader through the trends of the literature in the past five decades. It is definitely not an accessible book for the layperson, but if you plan to do scholarly work in the field of WWII studies, this work is a must.
