While its not all of Human knowledge it's a very important part of it, our history.
Ultimately if the goal is for it to survive societal collapse to the point where knowledge gets lost then books are a better bet than any digital storage. As such most large libraries hold the knowledge needed to take us up to the industrial revolution at least. Semiconductors is hard to teach in only text, by that point you really need the ability to produce the machines needed etc. But the underlying theory will be in a library. Also a lot gets proprietary and trade secrets when we get within the last 30 years and that knowledge won't ever get written down in a central repository until it's aged out of being protected.
