I think the seats in the silent areas are not sufficient for students and always busy, however, most students take "booked rooms" for chatting to their friends, I think. Its not fair others who wants to study in silence and cannot find place to do
Thank you for your enquiry. Please make sure you are aware of and use the SILENT study rooms on levels 4, 5 & 6. There are two rooms per floor available on a first come first served basis. These will suit your learning style much more than the open floor areas throughout the library. There are approximately 60 silent study spaces per floor - ie total of 180 places. Although these are in demand they meet the needs of the University community.
The Booked Rooms you refer to are Group study rooms which are available for precisely that - group study. It is inevitable that a great deal of chatting is essential to the group study process. If however if you mean "party" level noise that is not acceptable Students booking rooms have to adhere to the terms and conditions and unacceptable noise is one of those, full terms and conditions can be found here:

If a room is too noisy or you have any other issues you should notify the staff at the level 1 Customer Service desk or security on the Ground Floor.
