The Hogwarts library contains tens of thousands of books on thousands of shelves. Included in its many sections is an Invisibility Section, a section with information about Dragons, and a Restricted Section at the back, set off with a rope. "A warning: If you rip, tear, shred, bend, fold, deface, disfigure, smear, smudge, throw, drop, or in any other manner damage, mistreat, or show lack of respect towards this book, the consequences will be as awful as it it within my power to make them." - Librarian
