I think I mentioned this on another thread, but a very good (although now dated) look at how the North American continent is divided is Joel Garreau's "The Nine Nations of North America." My excerpt is packed w/my undergrad notes, so unfortunately I can't access it for details, but it's a hugely interesting & different perspective on North America. For linguistic differences & dialects, try Bill Bryson's "Made in America" & "The Mother Tongue: English & How It Got That Way," Allan Metcalf's "How We Talk: American Regional English Today," & Jim Crotty(aka The Mad Monk)'s "How to Talk American." (My undergrad degree is in cultural/political geography & I had a no. of classes on these topics.)
