【摘要】 文章通过对图书馆核心期刊载文、高被引文献和最新文献等三种数据源中研究机构、作者和关键词进行文献计量分析,比较其在图书馆学主题研究特性的异同和优劣。研究发现:核心期刊数据源集聚度略高于高被引数据源、远大于最新数据源;关键词归类中,核心期刊数据源偏向于服务方面的应用研究、最新数据源侧重于图书馆史方面的研究、高被引数据源则兼顾管理和基础研究;对图书馆学研究热点及其演进的研究,需将核心期刊和高被引数据源结合起来使用,才能得到全面、可信的结论。更多还原

【Abstract】 The article makes a statistical analysis on research institutions, authors and keywords in three data sources, including the core library journals, highly cited literature, and the latest literature, and compares their similarities and differences in library science research. The results show that the concentration of data sources in core journals is slightly higher than that of high cited literature and much larger than the latest literature. In the keywords classification, the data sources of core journals are focus on services, the latest literature on the history of libraries, and the high cited literature on the management and basic research. In order to reach a comprehensive and credible conclusion on hotspots and evolution of library science research, it is necessary to combine the data sources of core journals and high cited literature.更多还原
