The Capital Library, located next to Warwick Bridge, No.88 East Third Ring South Road, has no rest days all year round, which means that the Capital Library is open 365 days a year. The Capital Library is free for readers. As long as I show my second-generation ID card and the corresponding deposit (divided into 50 yuan, 100 yuan, 200 yuan and 500 yuan according to different functions), I can apply for the joint reader card of Beijing Public Library at the accreditation office on the second floor, which can be used in the Capital Library, district and county public libraries, some street and community libraries and the National Digital Library. Capital Library can bring laptops into the library, but not computer bags.
