The paper analyses the citation impact of Library and Information Science, LIS for short, research articles published in 31 leading international LIS journals in 2015. The main research question is: to what degree do authors' disciplinary composition in association with other content characteristics of LIS articles affect their citation impact? The impact is analysed in terms of the number of citations received and their authority, using outlier normalization and subfield normalization. The article characteristics analysed using quantitative content analysis include topic, methodology, type of contribution, and the disciplinary composition of their author teams. The citations received by the articles are traced from 2015 to May 2021. Citing document authority is measured by the citations they had received up to May 2021. The overall finding was that authors' disciplinary composition is significantly associated with citation scores. The differences in citation scores between disciplinary compositions appeared typically within information retrieval and scientific communication. In both topics LIS and computer science jointly received significantly higher citation scores than many disciplines like LIS alone or humanities in information retrieval, or natural sciences, medicine, or social sciences alone in scientific communication. The paper is original in allowing joint analysis of content, authorship composition, and impact.

翻译：本文分析了2015年发表在31种国际顶尖图书馆与信息科学（简称LIS）期刊上的研究论文的引文影响力。主要研究问题是：LIS论文作者的学科构成与文章其他内容特征在多大程度上共同影响其引文影响力？通过离群值归一化和子领域归一化方法，从论文获得的被引次数及其权威性两个维度分析影响力。采用定量内容分析方法分析的文章特征包括主题、研究方法、贡献类型以及作者团队的学科构成。论文的被引情况追踪从2015年至2021年5月，引用文献的权威性通过其截至2021年5月获得的被引次数衡量。总体发现：作者的学科构成与被引分数显著相关。不同学科构成之间的被引分数差异主要出现在信息检索和科学传播两大主题领域。在这两个主题中，LIS与计算机科学的学科组合获得的被引分数显著高于其他单一学科组合——例如信息检索领域中仅含LIS或人文社科，以及科学传播领域中仅含自然科学、医学或社会科学。本文的创新之处在于首次实现了对论文内容、作者构成与影响力三者的联合分析。
