I have a really old copy of Black Beauty that I'd like to try and repair as it has been one of my favorite stories since childhood. I am very much an amateur at book binding, and I've never tried to repair such a delicate book before. The paper is quite fragile and has begun tearing. Any advice would be appreciated, or is this book too far gone? It also appears to have been stapled at some point in its life.
