DBS has two libraries which are used by all students as an integral part of their learning. Both libraries remain open during the school day. Oliver, the computerised library management system, which is available on all school computers, provides quick and precise searching for library resources.

The Main Library houses an extensive range of resources in a variety of media and aims to support and encourage the development of student’s information literacy skills. Study space, computers and internet access facilitate research work. The library subscribes to a range of online resources and periodicals, both general and specialized. The continual development of the fiction titles encourages wide reading for leisure.
