This is such a neat piece of ephemera! I found it while searching through old books online. This is one of those cases where I forgot to write down where I got it from (oops!), so I can only credit HathiTrust's vast resources. Check out that potential late fee of a whopping 1 cent!
I learned from a little searching that the Boston Library Society was a subscription library founded in 1792. It had many notable members until it merged with the Boston Athenæum in 1939.
Being from Boston and loving libraries, this is an extra-special find to me. I hope other book nerds and ephemera lovers will appreciate it, too!
