SSME (Service Sciences, Management, and Engineering), a concept created by IBM, is essentially the same as service innovation for library and information institutions. When service is provided, it brings interaction between people, in which value is created and acquired. “Service science” and “service innovation” are two different concepts, but are closely related to each other. Service science includes service innovation; on the other hand, service innovation is one of the important concepts of service science and it also is an important way of realizing service science. Under the notion of service science, the old methods of traditional service can no longer meet the needs of the user. Therefore, library and information institutions should provide experience service and professional service to realize the people-centered service and implement innovation service to create value. In the end of this paper, the example of Shanghai Library is given to illustrate the viewpoints of the authors.
