I would argue that the library contains no information at all based on the fact that its entire inventory could be generated by a very short program. It couldn't have much of a card catalog either because the index number for each book would have to be as long as the whole book (on average, within a constant factor), so it would be impossible for a user of the library to make an information profit. I remember reading something along these lines decades ago when I used to be interested in philosophy but I can't remember the reference. It may have been something by Dennett but would predate the reference given in the article.
