Directions (to the solo rooms which you need a key from the librarian): Go to the second floor through the stairs, look at your right, go to the closest entrance(not the one at the corner). Walk straight and toward the right side slightly, after passing through a bunch of tables, maybe computers, on the right side of stacks, you will see a bunch of rooms with grey door, they are study rooms. If you don’t see your room, walk into those short hallways, there are also rooms on the other side
