How We Verified
This site separates confirmed public-source mappings from values that still need an in-game pass. Floor 1 sections 1A-1J and Floor 2 sections 2A-2G are listed with their current known categories. Unconfirmed shelves stay marked as TBD / verify so players do not memorize invented data.
Before publishing a new shelf mapping, we compare the book code, the shelf label, and the spine-color cue in a live Clean The Library server. Codes and likes are rechecked daily because Roblox games can patch reward systems without notice.
