All 16 Shelf Sections in Clean The Library

The library in Clean The Library is split into themed shelf sections, and every book on the floor belongs on one of them. Each section has a code made of a floor number and a letter, like 1A or 2C, and each section is tied to one Roblox theme such as Studio, Simulators, DevEx, or Brainrot. Your job is to grab a book, read its theme, and walk it to the matching shelf. This list lays out all sixteen sections so you can learn the map and stop guessing where each book goes.

How the floor and letter codes work

Every shelf has a two-part code. The first part is the floor, so 1 means the first floor and 2 means the second floor. The second part is a letter that marks the shelf in order, so 1A is the first shelf on floor one and 2A is the first shelf on floor two. Once you know a book's theme, the code tells you exactly which floor to head to and which shelf to look for. The first floor holds ten sections (1A through 1J) and the second floor holds six (2A through 2F).

Sorting books by theme is the whole loop

Books are sorted by what they are about. A book about building in Studio goes on the Studio shelf, a grind-and-upgrade title goes on Simulators, and a spooky one goes on Horror. The themes are Roblox genres and topics, so reading a title usually tells you where it belongs. The faster you can match a book's theme to its section code, the faster you clear the floor, which is why learning the section map is worth more than running back and forth checking shelves one at a time.
