How long? I don't think a library would last more than 100,000 years given natural disasters and plate tectonics etc. All you need to do is make a reading device that can last for a similar amount of time. And if the device itself wouldn't last that long then you could provide as much long-lasting equipment or material as possible to help build it.
The scenario you're describing is incredibly specific. It requires a post-apocalyptic world where humans have survived, but have somehow completely lost all ability to access past knowledge. Civilization must be advanced enough to access and read a library that has been shielded from the elements for millennia, but not advanced enough to build microscopes or lasers, even when given precise instructions on how to do so. It must be far enough into the future that any possible small high-tech reading device we could create is unlikely to have survived, but not so far into the future that a very large library structure is likely to have collapsed.

100000 years is a very long time. And in that time, you have good chances of reeboting civilization and reconstructing our current industrial world.

Easier said than done, and why would you need to do it, if libraries already solve the problem?
BTW I think we're considering two different scenarios. Libraries are excellent at solving the scenario given here, i.e. the internet collapses tomorrow.
