Each Sky-reaching Library has its own unique name and its own specialized knowledge classification.
Yang Yu casually selected the Third Sky Library of the All Things Library, named "Creation," which almost encompasses all knowledge about manufacturing in human history.
From the ground floor up, knowledge in the Sky-reaching Library deepens, and the higher you go, the more access you need.
Ordinary library members are only allowed to roam below the tenth floor. Even so, the knowledge listed on these ten floors is so vast that even if a person glanced through it all for ten years, they might not be able to finish.
These ten floors mainly use compact shelving to save space for storing books and multi-tier shelving to save indoor space. The aisles between shelves are just wide enough for one person to search for books, and if two people meet face to face, they have to turn sideways simultaneously to pass by.
