This is off topic but there is a map provided showing the locations of the panzer wrecks and a QR code that can be used by owners of smart phones to show the location on google maps. I find this book to be important because the battle within Berlin has a technical and tactical side that needs this level of investigation. I have found some books about the battle of Berlin lacking in this area and without this level of detail.
