This study examines the exchange of citations between two disciplines – Educational Technology (ET) and Library and Information Science (LIS) – as an indication of their interdisciplinary impact. The study was conducted in three phases. The first phase consists of an analysis of citations from ET journals to 15 top LIS journals; the second phase examined citations from LIS journals to 15 top ET journals; the third phase studied the five LIS journals – not on the original list of 15 – to cite ET journals and the relationship of citations from ET journals to them. The findings of this study reveal that about 1/10 LIS articles and 1/30 ET articles in the study sample were cited at least once in an article from the other discipline. This suggests that LIS has slightly stronger impact on ET research than vice versa. Among specific journals, the Journal of Education for Library and Information Science and the Journal of Documentation in LIS and Educational Technology Research and Development and the Journal of Educational Technology and Society in ET were most cited in the other discipline. Overall, the findings indicate a fair amount of exchange of ideas between the disciplines of LIS and ET. These findings are significant for interdisciplinary researchers in both ET and LIS as an indication of the links between and impact of these disciplines.

这项研究考察了教育技术（ET）和图书馆与信息科学（LIS）这两个学科之间的引文交流，以表明它们之间的跨学科影响。该研究分三个阶段进行。第一阶段包括分析从ET期刊到15种LIS顶级期刊的引用；第二阶段检查了LIS期刊对15种顶级ET期刊的引用；第三阶段研究了5种LIS期刊（不在最初的15种期刊中），以引用ET期刊及其引用与ET期刊之间的关系。这项研究的发现表明，该研究样本中的约1/10条LIS文章和1/30 ET文章在其他学科的文章中至少被引用过一次。这表明，LIS对ET研究的影响略强于反之。在特定期刊中，在其他学科中，引用最多的是《图书馆与信息科学教育杂志》和《 LIS与教育技术研究与开发的文献杂志》和《 ET的教育技术与社会杂志》。总体而言，研究结果表明，LIS和ET学科之间有大量的思想交流。这些发现对于ET和LIS的跨学科研究人员而言具有重要意义，表明了这些学科之间的联系和影响。
