In "Operation Barbarossa: The German Invasion of Soviet Russia", author Robert Kirchubel combines three of his earlier works on the initial stages of German invasion of the Soviet Union in 1941 (Operation Barbarossa) into this one volume. Each of the earlier books were originally written for Osprey Publishing's Campaign Series. The three individual books were in the typical campaign format... typically about 96 p. long, consisting of analysis of the campaign, commanders, forces and styles of warfare, pictures, illustrations, and maps.
