Even if you disregard violent causes for possible book loss, however, you end up with the fact that unless exceptional planning goes into how to preserve them, you end up with parchment crumbling to dust in a few hundred years anyway, and what good is that to anyone. I doubt any amount of honor of K8P can stop the passage of time.
The best way to preserve knowledge is to create new copies of old books. Every book right now on the planet will eventually crumble to dust, no matter how well preserved it is. But if libraries continue to exist, than the books and the records they hold will continue to exist... that said, we don't have magic runes. The dwarves do. They
can make a library that lasts forever, or close enough. And they happen to live on a war-planet where a library that can be a permanently secure record would be
incredibly useful.
[X] Preservation
I was really really
really split on this. I want to have faith in K8P, and in our decision to put a library here because K8P
will not fall. But at the same time, what's the best improvement for our library? How do we make it
the library, putting in consideration the needs of the people and world it's made for? Order is, ultimately, a solvable problem. Something we and future librarians can work on to do in the future. But preservation, on the other hand, is something that we simply can't add in to an equivalent level unless we build it into the bones of this place. A library that can
survive an apocalypse is something of immeasurable worth to a planet that's been hit with said apocalypses multiple times. It will be a defining feature for anyone who would ever use it: Books you store here will be kept. No matter what.
And what if the worst does happen? What if, some hundreds of years hence, K8P does somehow fall, yet the library remains? The lost K8P will hold something worth more than gold, or dwarven favor, or trade, or strategic location, or all of the above combined.
Knowledge, from all over the world. And in such a worst-case scenario, the library would be a reason for people all over to help re-take K8P. Our library could become a cornerstone that itself helps keep and preserve K8P. And what more could a library aspire to?
