Since the Library of Alexandria was primarily allowed to decay or be destroyed because it was seen as an interesting hobby for the nobility rather than a practical tool, I was wondering how it could be preserved. It seems the best way to do this is to make it too valuable to lose, so how could the works of the Library be put to good practical use? What sort of machines, techniques, methods, and tools could the ancient world have invented with the knowledge contained in the Library's scrolls?
