From the dawn of civilization to the modern era. ""Historical Maps On File[trademark], Updated Edition"" is the volume librarians requested most when asked for suggestions about additions to our popular ""Maps On File[registered]"" collection. More than 400 redesigned maps - approximately 100 new to this edition - add clarity and detail to this expanded edition. Updated maps reflect the latest changes on the world stage. Approximately one-third of the collection is devoted to American history, covering such topics as Native American populations prior to European collaboration, ratification of the Constitution slavery, and presidential elections.
