Our school library offers learning services, books and other things that help all members of the school to become good thinkers and clever users of information. It is linked (连接) to the larger library in the city and the World Wide Web. All these services are given according to the requirements of the Public Library Manifesto (声明).

　　School library services must be given to all members of the school. Students of any age, class and grade can enjoy them. Different services must be given to those who are unable to use the main library services.

1. Opening and closing times:
