hello, I was wondering if anyone knew if the apartment in NYC that Twain stayed in was still there and what the address of it is? And! if the NYC library has any interesting Mark Twain material? I am going to NYC the 1st weekend in Oct with my husband. He will be at a conference and I was looking for some research to do while there. (Otherwise I'll have to go shopping and spend money I don't have.) Thanks so much! Jules
