Book Piles

We spent the latter half of the day removing every single newly shelved book. My hands are cramping, and my muscles are sore. On the ground are piles and piles of books. A collective of everything that civilizations thought was important enough to document at one point. I honestly don't know where to start. Malory had never even heard of the Dewey Decimal system before. I know it's 2015, and computers solve much of the complex filing. But how can you become a librarian and at least have some idea of it. I feel like I'm over my head . Can I do this? Maybe I just need to take a walk away from here. Go to the gym or something.
