Under a global environment characterized by open and complex information, academic library resource-sharing practitioners should observe the information-service market beyond a “library-oriented” setting and rethink the development direction of the service. To investigate this issue, this paper presents an analysis of the development trajectory and characteristics of DXY, a Chinese information service enterprise. This study also discusses the development of academic library resource-sharing service from three dimensions, namely, service targets, service contents, and service roles. Findings show that the academic library resource-sharing practitioners should break through the traditional cognitive framework of “academic users on campus” and “document providers,” and furthermore, consider upgrading the service to assume a comprehensive role as information sharer, information connector, and platform operator simultaneously. This change will enable the move toward a knowledge service orientation.
