We've been able to manage to make very good microscopes for quite a while. It won't take much more than industrial revolution level tech for this to work

  If you have industrial revolution tech, you can already maintain and mass produce libraries of books. Probably quite easily.

    What about all the information that was lost in the meantime, because you weren't maintaining it then?

      The counterpoint is the same: what happens to all the nanofiche disks next to a pile of crushed microscopes that were destroyed when the roof fell in? In one case, the information which mattered to the people at the time persisted. In the other, no information persisted. The whole point is that the operation persists for longer than a human lifespan. If we have to rediscover 100 years of making lasers and rockets, who cares? If we have to rediscover 2000 years of agriculture and medicine, that's a problem.
