Joe, I'm sorry to hear of your (long ago) problems getting into the folklife collection. I'm only on break right now, so I can't track down the previous thread, but I can suggest to all and sundry, that if you want to visit a special collection, whether it's the whole library or part of a larger library, a phone call or e-mail beforehand could make a difference. Special collections librarians are usually glad to have visitors - besides meeting a kindred spirit, some places keep count of the numbers of visitors, questions, etc. for the annual report, and that helps justify the budget for the existance of the collection, and the librarian's job. When I visited there (too long ago), I was expected, and had no trouble getting in.
