This will eventually be available through UMI (for money) and through UNC Library (for free); in the meantime feel free to access it here for use in any way consistent with the copyright.
The maps below are ones I put up a while back, but they are basically the same as some of the ones in the diss itself.
You can view the pictures here, or click on the "PDF set" link below to download them all as pdf files for easy printing.
I have not put the individual by-year maps on this page, but you can download the set as gif files, or watch the Powerpoint animation (links below). If you don't have Powerpoint, you can download a free viewer from Microsoft.
