Latest arrangements on services of Hong Kong Public Libraries

In view of the latest situation of COVID-19, the Leisure and Cultural Services Department (LCSD) will adopt further measures to maintain social distancing. From 10 December 2020 (Thursday), all public libraries and their students’ study rooms and mobile libraries will be temporarily closed until further notice. Book drops of the Hong Kong Public Libraries and those located at MTR Central, Kowloon Tong and Nam Cheong stations as well as the self-service library stations (at Island East Sports Centre Sitting-out Area, the Hong Kong Cultural Centre and Tsuen Nam Road, Tai Wai) will continue to provide service. Public libraries will continue to provide online services such as e-Books and e-Databases. During the period, overdue fines will not be generated for late return of library materials, and due date of reservation pick up will be extended accordingly. Please refer to the library notice on the special arrangements details.
