The Library (Unbound Universe)

The Library was one of the last vestiges of knowledge in an alternate Doctor's universe.

It supposedly saved all the books in the universe. The whole library, however, was parasitic and stole knowledge from its visitors - reading them. The books themselves all had blank pages which projected knowledge from the minds of its readers. (AUDIO: The Library in the Body)
