Abstract
Contemporary society is an information society with highly developed information. Its network and digital characteristics are bringing tremendous changes to the whole society. China's library and information science is no exception, and its research content is also expanding. It is a core journal that can reflect the actual situation of research in the subject area and conduct academic exchange as an authoritative representative of a certain subject area. Therefore, it is of great practical significance to conduct comprehensive research based on the development history of library and information science, quantitative and qualitative analysis of academic journal articles, research related topics and keywords, not only to further understand library and information science, but also to accumulate knowledge of library and information science, and also through scientific development trend, based on the experience summarized by the predecessors, allows us to more fully recognize the important role of library science and information science, and to improve the theoretical literacy and research level of relevant researchers. At this stage, it is even more necessary for researchers to look at and study library and information science with a developmental perspective. Based on this, the article mainly analyzes the research significance of library and information science, and analyzes the output of China's library and information science journals. It uses Ucinet software to visualize the main research hotspots, and finally analyzes the dynamic factors affecting the research of library and information science in China in order to provide a reference.
