The library is two stories tall, and is filled wall to wall with books. On the lower floor, there are tables and chairs where students can study, as well as also a media section where students can play video games. The upper floor appears to only have bookshelves.
In "Ladybug & Cat Noir (Origins - Part 1)", the bottom floor of the library has a TV that shows live videos from four security cameras. In the videos, the front of the school, the main court from above, Mr. Damocles' office, and Miss Bustier's classroom can be seen.
