The Hogwarts Library from Every Harry Potter Movie
The library at Hogwarts always has what you are looking for, but apparently a really, really bad catalog system. If there were just Subject categories for “Nicholas Flammel,” “How to Breathe Underwater,” and “The Chamber of Secrets,” then this series could have been about half as long. Come to think of it, we never hear about any librarians. Maybe they were the victims of cutbacks. See what happens when you cut back on library staffing? You risk Voldemort taking over.
