Archives of Appalachia

I'm always looking for good research resources - anything where I can flood myself with undue quanitities of data and/or images, thus overwhelming my mind until suddenly, somehow, I put it together into a single mass of theory. That said, I'm pretty familiar with research methods, datasets, and archives, including this one.
The Archives of Appalachia, which are administered by East Tennessee State University, down in Johnson City, are a lot of things and they aren't others. They are an enormous collection of data and photographs which are pretty readily available with an e-mail or a phone call. They are not, however, fully digitized. Thus, I'll lay it down for you. If you're interested in virtually any subject, be it political, cultural, economic, or social, within the region to the degree that your inquiry might be called scholarly or at least moderately obsessive, this website warrants some investigation - you'll probably be calling for photocopies within fifteen minutes. If you want, on the other hand, a Captain Eo-esque light and whistle show, well this isn't it. Sorry
