It starts at the beginning of European colonization and finishes at, and including, the Civil War. Currently, I own no books on US history at all, but I just bought Middlekauf's The Glorious Cause. However, I've been told it only covers from the Seven Years War and up to the end of the Revolution. What other books should I buy as well?
Go to the college and bookstore website; and find out what books they use. At the back of those textbooks, there should be a bibliography; pick what sounds interesting.
