The best way to tell if it's a library is to pick up any book, open it up, and if somewhere on the first or last few pages, there's a stamp that says it's a library book, it's probably the library. Either that, or it's a book store. And usually those stamps tell you what library the book belongs to, and the address. I actually live nearby to a library, so if we're in luck, I can come keep you company and help you get adjusted in just a few minutes!
