Purpose: This study explores new content, forms, and fields of science and technology(S&T) innovation and entrepreneurship information services of the National Science Library of the Chinese Academy of Sciences(NSLC).Design/methodology/approach: We cooperated with incubator enterprises and set up an “S&T Innovation and Entrepreneurship Information Service Platform.” We designed five series of activities, including industrial information release, project financing and roadshows, entrepreneurial sharing, entrepreneurial coaching sessions, and entrepreneurial salons. Based on the implementation of these activities, we designed new NSLC library services for S&T innovation and entrepreneurship.Findings: Since the construction of the platform, these five series of activities have attracted more than 80 business projects, 90 investors, and 30 researchers. Furthermore, more than 20 media representatives and nearly 300 entrepreneurs have participated in the activities that the NSLC has organized in the past two years. Through these activities, we have defined an S&T innovation and entrepreneurship knowledge service model for the NSLC.Research limitations: The service practice of the NSLC is still in the demonstration phase. Due to staffing limitations of our service teams, the expansion of our service activities has been greatly restricted.Practical implications: The innovation and entrepreneurship information services of the NSLC provide a lot of material for transformation of library services for domestic and foreign special libraries.Originality/value: It is useful to transform library and business services by embedding them into ways in which we serve innovation and entrepreneurial activities. This opens up a new field of library knowledge services in China.
