Q. Where are 403A, 403B and 500M located in Cooper Library?

The room 500M is located just outside of the Adobe Digital Studio on the 5th floor. It's to the left as you walk up the stairs from the 4th floor.

Rooms 403A and 403B are on the main floor of Cooper Library all the way to the back of the building on your left if you are facing the Library Services Desk.
