There is no need to apply for a reader's card to enter the library, read in the library, have a rest, participate in lectures, exhibitions, film and television screenings and other reader activities, and there are no restrictions. It is free to apply for a reader's card for the first time. If you need to borrow documents, you need to open a deposit for borrowing authority, which is generally five volumes 100 yuan. This is the deposit, which belongs to permanent readers and can be refunded later. The deposit has been refunded, and the borrowing authority has been cancelled, but the reading authority in the library is still there, such as surfing the Internet, database retrieval, video on demand and so on.
