[Purpose/Significance] On the occasion of the 70th anniversary of “Library and Information Service” (LIS), this study aims to examine its knowledge production, thematic evolution, and academic influence over the past decade, thereby revealing its publishing achievements and scholarly contributions. [Method/Process] Based on 3,863 research articles published in LIS from 2016 to 2025 and related citation indicators, this study applies bibliometric analysis, social network analysis, and BERTopic topic modeling. [Result/Conclusion] The findings show that LIS has formed a stable and active core author community over the past decade, with its author collaboration network characterized by team-based collaboration, multiple centers, and cross-institutional cooperation. Its research themes can be summarized into six directions, including library transformation and services, open data and open science, reflecting the coexistence of the continuous deepening of traditional topics and timely responses to emerging and frontier topics. Both impact factors and immediacy indices show an overall upward trend, indicating the continuous enhancement of the journal’s academic influence and knowledge dissemination capability. These findings suggest that LIS has consistently attracted a strong community of highly accomplished authors and responded promptly to disciplinary frontiers and practical needs, and played an important role in promoting academic community building, guiding topic development, and facilitating knowledge dissemination. This fully demonstrates its publishing characteristics, academic value, and benchmark role as a high-level academic journal in the field of information resource management.
