：文章以从Google Dataset获取的93个国际图书馆学研究数据集为样本，对其外部特征进行计量与讨论，并遵循元分析法思想、利用文本挖掘工具对其内容特征进行定量和定性分析。研究发现，数据赋能的国际图书馆学形成“现代图书馆事业管理”“LIS教育与信息素养培育”“研究数据管理与共享”“科学计量与替代计量学”“信息与科学技术应用”“开放科学与开放存取”等六大前沿议题；展现出理论与技术融合创新提供了新基础、研究数据管理与共享上升为新焦点、开放科学交流与合作成为发展新趋势等三个研究发展方向。

Taking 93 international library science research datasets, which obtained from google dataset as samples, this paper quantifies and discusses its external characteristics, then following the idea of meta-analysis and with the help of text mining tools, to analyze its content characteristics with quantitative and qualitative analysis methods. It was found that the international library science from the perspective of data empowerment has formed six frontier topics: modern library management, LIS education and information literacy cultivation, research data management and sharing, scientometrics and altmetrics, information and science technology application, open science and open access. Three directions of research development are presented, including: the integration of theory and technology provides a new basis for innovation, research data management and sharing has become a new central issue, opening scientific exchange and cooperation has become a new trend of development.
