Oops, I forgot to respond to your second question. I think you are referring to "Exposing the Wilderness: Early Twentieth-Century Adirondack Postcard Photographers," by Robert Bogdan. As you know, it has an entire chapter on Ernest Ameden and his photography work. I ordered it directly from Syracuse University Press. Any book store or camera shop can probably order it for you, but I'd write directly to the publishers at Syracuse University Press, Syracuse, NY 13244-5160.
