Although China Geological Library is a professional library, its construction purpose should be the same as that of a large public library. Recording history, inheriting civilization and shouldering social responsibility means that China Geological Library should collect, protect and inherit all civilizations and cultures related to geosciences from the perspective of human history, so as to promote the development of geosciences in China and the progress of human society. China Geological Library, as the geoscience documentation center of China Geological Survey, has the same construction goal as "building a world-class geological survey institute" of China Geological Survey.

The construction purpose described here is more grand than the actual purpose of China Geological Library as an organization in reality, but only its grandeur can be closer to the first class.

In order to achieve this goal, the library needs a broad vision and ubiquitous social consciousness. The library on the internet should make every link have social attributes and interactive conditions, so that every action of users can produce benefits.
