I'm with kat's son here.
Bruce, in the past, I've used student's ID's to check out books at a university I wasn't attending. I'm not advocating anything here...also, I like to have librarians for friends in order to take advantage of the interlibrary loan stuff and perhaps bend a few rules. I also used a medical school library to copy articles (though I would have had to come up with and ID to check a book out.) Perhaps with the contacts at Mudcat, you could get warm bodies all over the world to personally go to various libraries. I can offer my services for Kentucky, and with a little effort, most of the colleges in the Southeast.
