Employing approaches adopted from studies of library and information science (LIS) research trends performed by Järvelin et al., this content analysis systematically examines the evolution and distribution of LIS research topics and data collection methods at 6-year increments from 2006 to 2018. Bibliographic data were collected for 3,422 articles published in LIS journals in the years 2006, 2012, and 2018. While the classification schemes provided in the Järvelin studies do not indicate much change, an analysis of subtopics, data sources, and keywords indicates a substantial impact of social media and data science on the discipline, which emerged at some point between the years of 2012 and 2018. These findings suggest a type of shift in the focus of LIS research, with social media and data science topics playing a role in well over one-third of articles published in 2018, compared with approximately 5% in 2012 and virtually none in 2006. The shift in LIS research foci based on these two technologies/approaches appears similar in extent to those produced by the introduction of information systems in library science in the 1960s, or the Internet in the 1990s, suggesting that these recent advancements are fundamental to the identity of LIS as a discipline.

图书情报学研究课题与方法的演进与转变

该内容分析采用 Järvelin 等人对图书馆和信息科学 (LIS) 研究趋势的研究采用的方法，系统地检查了从 2006 年到 2018 年以 6 年为增量的 LIS 研究主题和数据收集方法的演变和分布。收集了 2006 年、2012 年和 2018 年在 LIS 期刊上发表的 3,422 篇文章的数据。虽然 Järvelin 研究中提供的分类方案没有表明太大变化，但对子主题、数据源和关键字的分析表明2012 年至 2018 年之间的某个时间点出现了该学科的社交媒体和数据科学。这些发现表明 LIS 研究的重点发生了一种转变，社交媒体和数据科学主题在 2018 年发表的文章中占三分之一以上，而 2012 年约为 5%，2006 年几乎没有。基于这两种技术/方法的 LIS 研究重点的转变似乎相似与 1960 年代在图书馆学中引入信息系统或 1990 年代互联网所产生的程度相比，表明这些最近的进步是 LIS 作为一门学科的基础。表明这些最近的进展是 LIS 作为一门学科的基础。表明这些最近的进展是 LIS 作为一门学科的基础。
