The development of big data technology has brought a series of new content, opportunities and challenges to the library, and scholars have conducted many studies around this. This study obtained 98 related papers from the core collection of Web of Science, using the knowledge map research method, and using the CiteSpace software to analyze the number of annual papers, journals, authors, institutions, keywords and topic changes. The results show that scholars’ attention to this field has gradually increased, and the number of annual papers has increased year by year. China is the country with the highest contribution to the research, and the contribution of Chinese scholars is higher than that of other countries. Big data, university library, data management and information service are the key research contents of this field. In the end, this paper makes a research prospect, and scholars should further strengthen the research on user behavior, user portrait and intellectual property risk.
