Abstract: 【Purpose/significance】Academic cooperation is conducive to promoting the smooth development of scientific research
work, accelerating the output of scientific research results, and promoting academic exchange and knowledge fusion.【Method/pro⁃cess】Taking 7 CSSCI source journal papers in the field of library science from 2017 to 2019 as the research object, define and extract the actual and potential relationship between author and keywords. Co-occurrence analysis was used to identify and exclude the data of collaborators, and the potential relationship between authors was defined and the matrix was established based on coupling analysis.Cluster analysis and clustering effects are used to summarize potential cooperation groups, and potential cooperation themes are ana⁃lyzed through literature content research.【Result/conclusion】The research results show that there are 72 potential collaborators, 8 po⁃tential cooperation teams, 1 overall cooperation center and multiple regional cooperation centers in the field of library science. Poten⁃tial cooperation themes are divided into 7 categories according to clusters and several sub-categories according to individuals.【Inno⁃
vation/limitation】This discovery provides a reference for the cooperation of researchers.
