    When you use our university libraries there are different learning spaces available, so you can decide what is best for your purpose.

Social learning areas

We recognize that you can learn from your friends so we have provided social study areas in all our libraries. Here you can discuss your studies with your friends without worrying about disturbing others as a reasonable level of noise is accepted, though we do ask that you're considerate（替他人着想的）of other students and staff.

Group study rooms

There are bookable（可预订的）group study rooms of various sizes in the libraries. These rooms are well equipped so that you can easily work in groups or practice presentations.

·Bookings are available to groups of 3 or more students.

·Bookings can be made by hour（a maximum of 2 hours per group per day）.

·Bookings can be made for the current week and the following week.

·Contact the library's Help Desk to book a room in person. Bookings are restricted to student use only.

Silent study spaces

We know that on occasion you may prefer to stud yon your own. To help you achieve this we have individual quiet or silent study areas.

In order to preserve the quiet study environment and avoid disturbing other students, discussion about your course or exams, or using mobile phones isn't permitted anywhere in these areas.

Food, drink and phones

Cold drinks and snacks can be consumed（消费）in most areas of the libraries though we ask that you help keep the learning environment clean and pleasant for everyone by clearing rubbish into the bins provided.

Mobile phones can be used in the social learning areas and group study rooms but not in the silent study spaces or the hallways or stairs that lead to those areas. We ask that you switch your phone to silent mode when you come in the library.
