Abstract
Social media has become widely used in people's learning and daily lives in today's society. Social media applications in university libraries have become a significant research hotspot in library science. The service model of Chinese university libraries has undergone four stages of change. With today's internet connectivity promotion, it is worthwhile to explore how Chinese university libraries can develop innovative new service models through social media. This paper employs the methods of literature survey, network survey, and comparative data analysis to select 11 university libraries in northern China as the research subjects. Through the analysis of the functional data from their WeChat official account, we find that the development of social media in northern university libraries in China is uneven, and innovative functions and personalized services are lacking. It is recommended that Chinese university libraries prioritize innovation in information service functions, focus on user needs, expand functional innovation platforms, and explore the development of new information service models.
