Where can I talk?
Answer
The Reference Area (just past the Information Desk as you enter) is a place where people can work together and talk. Its seats cannot be reserved.
The Law Student Commons on L2 has group spaces that can be reserved. It is set up for common work (hence the name!).
Quiet talking is allowed in the Law Student Lounge (L113), but be aware that the room is not soundproofed.
Most of the rest of the library should be fairly quiet, so you and your classmates can focus on your work.
