why are there so many universities, libraries and books?

with so much information in this world, it becomes hard to imagine how there can possibly be any questions which remain unanswered. i guess the problem with this world is not that there are too many questions, its just that there are too many answers. for example, most puzzles, annoyingly, have more than one solution - and then there are plenty of answers that are just hanging around, waiting for the right question to pop-up. sometimes, maybe through boredom, (who can say?) these unattributed answers, attach themselves to irrelevant questions!

then, i get terribly confused.
