Do you need a place to meet with a tutoring student, meet with undergraduates in a class you teach, or work collaboratively with other GA's? These are the spaces for you!
"Do you know my GA? They said they would have office hours in the library today..."
Are you meeting with students? The Library has 200,000 square feet and almost 1,000 seats. Help them find you by being as specific as possible. Provide the room number or a detailed description of the area where you will be.
