Library [Fourth Floor]

The Hogwarts Library is located at the fourth floor of Hogwarts School of Witchcraft and Wizardry and contains tens of thousands of books on thousands of shelves. The library is where students can go to peruse or borrow books to supplement their studies (or for personal enjoyment). The library closes at 8:00 pm. The library books have various spells on them to prevent students from defacing or stealing them. Chocolate and (presumably) other food is forbidden.
Taking Out Books
Students and teachers may take out books from the library, with the librarian’s permission. Students may also be put on a waiting list for a book that's already out.
