Misha is the first to find something valuable, sending a Guild message that she's found an abandoned bookstore, and is carefully exploring in search of surviving texts. The magic in skill books might have kept them intact, and sometimes a double sealed case can preserve documents even without magic.
There is a glass topped case by the counter that has books inside that look completely intact, so Misha carefully heads behind the till to examine them. The case is latched shut with a locking latch that seems to seal the case, like a water tight door on a ship. The lock has been left off, so Misha carefully twists the latch open until, with a hiss of pressure equalizing, the case swings open.
The labels are in Gnomish, which none present can read, so Misha carefully removes the first tome and opens it to a random page in the middle.
