Before using the ladder, kill an archer.
Go down the ladder.
Once you get down, use the lever to open the passage.
Inside you'll encounter two warriors and an archer on the bookshelf. [1] On a balcony adjacent in this room you'll find a bonfire. [2]
Go up the stairs leading from this location (to the left), you'll reach a previous section on the library.
After exploring above path, return to the room, where you've descended the ladder. Go to the side chamber full of books, to open a chest (Blue Titanite Chunk).
In an adjacent chamber, also full of books but a bit larger, you'll find two more chest (you should find there: Archive Tower Giant Cell Key - a key to the location where octopuses were kept, Crystal Ember and Channelers armor) - WARNING, one of them is Mimic (hit it before opening).
In the same room use the lever, to open a descend down. [1] There is one more chest - open it (Prism Stones). [2]
Now go through fog.
Outside you'll get to a small forest with many crystal golems. [1] Go down the ladder and start the fight with them - it is enough to circle around slow enemies and attack them from behind. [2]
There is also a golden golem lurking in the area - he is tougher and has a greater range. So it means that you won't be fully safe behind his back.
A few opponents are lurking next to walls - so watch out. In the center part of the location you can collect Crystalline armor, [1] and next to the wall on the right you'll find Blue Titanite Chunk. [2]
After collecting items, head towards Crystal Cave.
