The Rubaiyat went down, but was recreated twice-during the 30s, and again in the 90s I believe. The 2nd Rubaiyat was destroyed in the blitz . There is an interesting article on the saga of this book on this site. Does your question also mean to ask what kind of books were provided in the 1st and 2nd class lounge and library? Im guessing general topics, but would be interested to know myself if anyone else knows.
