In this room, there are four book shelves that can be move by switching the button. The stairs mainly leads to another rows of books including a door to the Main hall 3F. The books are filled with various content of chemistry and Company data files on Umbrella. The door below the staircase at the far ends leads to the Main Hall 2F.
The four book shelves at front are unable to be move because the power is off. The power can switch at the right back which can be access by going toward the stairs until reaching a broken passage that can cause Leon or Claire to fall down. Inside that small room, there's a bronze plate with a picture of a warrior with it. There's a puzzle in this room where the four book shelves need to be move according to the right pattern. Switch the book shelf at the far left to the right and do the same with the book shelf next to it to open the bronze plate shutter, revealing a Bishop Plug for Leon and the Serpent Stone for Claire.
