Abstract: [Purpose/significance]Computers play an irreplaceable role in the ternary world formed by humans, machines and objects. And they are silent forces for social change. With the digital age evolving to the data age, scientific research has entered into the fourth paradigm. Both the scientific community and the individuals have a strong thirst for more in-depth, more convenient knowledge services. Under the urge of academic users, the research libraries are actively promoting the user experience of knowledge service, which will help users to expand knowledge discovery, and reveal the knowledge contained in the literature. Knowledge service can build the link among the knowledge and formulate the knowledge maps. Content-based knowledge service is the inevitable choice to break through the bottleneck of knowledge acquisition in the context of machine learning prevalence.[Method/process]This paper systematically reviewed the practice of knowledge services in American research libraries, and further analyzed the core content of the services. New contents of knowledge services given by the rise of research data were also clarified by this research. At the end of this paper, the author demonstrated the development trends of the knowledge services.[Result/conclusion]The content-based knowledge service is the inevitable choice of the library for the data age. Data turnover efficiency is the future determinant of the amount of scientific research output. Knowledge services will become increasingly fragmented, associated and mobile.
