It might be - Apocrypha is described as:

"Morian Zenas described to me an endless library, shelves stretching on in every direction, stacks on top of stacks. Pages floated on a mystical wind that he could not feel. Every book had a black cover with no title. He could see no one, but felt the presence of ghosts moving through the stacks, rifling through books, ever searching."
