From BMC to NYC: The Tuelary Years of Ray Johnson is another publication of the Black Mountain Museum and College. Copies were still available on my visit but I would get them quick if Vincent Katz's Black Mountain College: Experiment in Art, published by MIT Press is any indication. That book is out of print and was selling for as much as $200 online. The Strand seems to have a copy now for $90. If you are interested I would suggest you go out and grab it as it is an essential resource. Black Mountain related material seems to appreciate at a fantastic rate. From BMC to NYC is currently on Abebooks for over $300, which is Exhibit A for just how ridiculous Abebooks has become. I bought my copy at the Museum for $15.
