…the maps are detailed, wide-ranging and accurate. They also look great. Each map contains a wealth of information and stories, so to have such a wide range of topics covered is a fantastic resource. I chose to use the maps in a BBC video because they are a very clear way to show changing borders in Europe and there were so many dates available through history. It was the biggest and clearest range of maps I could find.
