The 24-hour self-service branch of Hunan Library opened its doors to residents with a new look on March 20.

After months' renovation, the 24-hour library is now 2.5 times the size of the original and its collection of books has also doubled. It has so far become the largest and most comfortable 24-hour self-service library in the urban area of Changsha.

Featuring self-check borrowing and returning, the library has brought great convenience for its main reader groups such as the office workers. Since its first opening in April 2012, the library has seen a reader base of more than 15,000 members.
