You mean the 2nd class library? Never came across any information that this was done.
That area is badly damaged. A & B Deck hat collapsed on C Deck (especially the area about the aft 2nd staircase were the mast is) and meanwhile the situation is much worse.
However, an ROV had been send to the still existing 2nd class promenade on C Deck (outside the staircase) but I think they took only exterior images and did not send the ROV into the promenade. I doubt they could have send it deep inside there.
Yes, I guess they wouldn't have too many decades before the library is collapsed too much.
