Very nice library and approachable staff. How I wish the management does something about the very impolite and ill-mannered people talking so loud on the phone. When I go to library, it is usually to have a calm atmosphere to study and focus on my assignments. But with this library, I always think that people come here every day just to talk on the phone and disturb the order. How can you put a whole 30+ minutes conversation on a speaker?
