StamperMA: you may want to further check out the Boston Athenaeum, the oldest private library in the USA, founded in 1807 (
www.bostonathenaeum.org ). I found about it in a Christian Science Monitor news article from some years ago. I have never been to Boston, but visiting the Athenaeum would be high on my priority list.
It is a membership library. But you can probably sample some of the "delights" in a short visit. It's at 10 1/2 Beacon St.
