Query: Very useful supplement to a study of U.S. History

I use this book in the Grade 11 U.S. History class that I teach and I must say that it is very useful. Maps cover dozens of topics from the original settlement of North America to the 9/11 tragedy. The maps are in black and white, making them easily used if you need to reproduce them.There is the downside that some of the maps are a little unclear. There are also a couple of maps (#51 and 52) dealing with slavery that show the Indian Territory as a part of Texas.However, for a teacher of High School U.S. History, this is a valuable supplement. This is also recommended for any student of U.S. History (either high school or university) and anyone else who would like to get a spatial view of the currents of U.S. History.
