The National Knowledge Resource Service Center and its portal are under the guidance of the Central Propaganda Department. It is the general entrance and exit of the national knowledge service platform and a window showing the knowledge resources gathering and construction of the knowledge service platform in the publishing industry. It is also a window serving the management departments and pilot units of various knowledge resource service models. The portal mainly provides technology, standards, copyright protection and other services for pilot units of various knowledge resource service models, and at the same time drains and guides each other's knowledge service sub-platforms. It also promotes the transformation and upgrading of knowledge service in each pilot unit to ensure the healthy and orderly development of the knowledge service industry. <<
