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 signed note from a teacher is required to peruse that section of the library; it contains books of Dark Magic only used by older students studying advanced Defense Against the Dark Arts. The library closes at 8 pm.

The library books have various spells on them to prevent students from defacing or stealing them. The librarians sees themselves as the guardian and protector of the books and is at odds with the students who try to use them.
