The first library ATM (self-service book station) in China was officially put into use in Dongguan Library in December 2007. Without restriction of service hours and geography，the library ATM is placed in residential neighborhoods, hospitals, squares to serve readers conveniently. It compensates for the lack of the number and service of grass-roots libraries. The library ATM, the physical library and the bookmobile service form a better service network. They are complementary with the digital library in 24-hour information service to meet people’s diverse needs for knowledge.
