可信数据空间建设是我国数据治理的重要组成部分。图书馆参与可信数据空间建设有着坚实的公共逻辑、服务逻辑和制度逻辑基础，能够发挥出数据资源、数据管理、知识服务、信任构建等多重价值。在建设实践中，图书馆及行业需要积极行动，在国家政策中找到切入定位，在实践探索中找到最佳模式。欧洲数字图书馆和美国Civic Switchboard项目为我国图书馆可信数据空间建设提供了启示与借鉴。

The construction of trusted data space is an important part of data governance in our country. The library's participation in the construction of trusted data space has a solid foundation of public logic, service logic and system logic, which can give full play to the values of data resources, data management, knowledge service and trust construction. In the construction practice, libraries and industries need to play an active role, find the cutting position in the national policy, and find the best model in the practice exploration. The successful construction of European digital library and Civic Switchboard provides reference for the construction of trusted data space in Chinese libraries.
