Ienzo blinks at the question. That saving something is certainly going to happen, he barely even knows what's in the library to begin with, much less how it organizes its boo-- its scrolls. As such, he rather suspects that they'll simply have to save what they can.

It's regrettable really, but it's not like he can see a way to figure out what's where and so he offers a shrug that manages to imply that it's probably more likely to be whatever they can find.
