If you would like to know more of the destruction of Russian art, antiques, historical buildings libraries etc., the book I would recommend to you would be Pavlovsk : The Life of a Russian Palace by Suzanne Massie. This is a wonderful book for those who appreciate the Imperial palaces and the great struggles that the curators have endured to preserve them. I need to accquire another copy of the book because I gave mine to the Head of the Rumiantsev Palace (which houses the Seige of Leningrad Museum on the second floor) in 1996.
Two other books with a larger scope are Beautiful Loot: The Soviet's Plunder of Europe's Art Treasures by Konstantin Akinsha and Grigorii Kozlov; The Rape of Europa, The Fate of Europe's Treasures in the Third Reich and the Second World War by Lynn Nichols. In regard to this second book, the late Captain Walter Farmer, USAR of the MFAA (the unit charged by the US Government with the task of collecting Nazi looted works) told me some six or more years ago that this book greatly exagerated the role of US soldiers in stealing looted items from the Germans in the post war period, in particular he found the stories relating to the Hungarian Gold Train to be exagerated.
