The Yu Chun Keung Medical Library, formerly the Lee Hysan Medical Library, is named in memory of the late Mr Yu Chun Keung for his generous donation and support. Completed in January 2002, it is designed as a state-of-the-art facility in the Faculty of Medicine Building, well equipped with sophisticated information technology to provide a virtual learning environment conducive to study and research.

The mission of the Yu Chun Keung Medical Library is to serve the curriculum, research, continuing education, and patient care needs of the University of Hong Kong and its Medical Faculty. It is an integral part of the University Libraries comprising significant digital resources, multimedia as well as extensive print collections on biomedical and health sciences. Its overall aim is to become a regional centre of excellence in support of teaching, research and scholarship in these fields. The Collection traces its origin back to the founding, in 1887, of the Hong Kong College of Medicine for Chinese, forerunner of the University of Hong Kong Faculty of Medicine. The Library became a World Health Organization Depository Library in 1993.
