Exploring the interdisciplinary characteristics of library and information science (LIS) from the perspective of interdisciplinary LIS authors

Largest contribution to LIS by external disciplines as measured by the characteristics of research articles

The paper analyses Library and Information Science (LIS) articles published in leading international LIS journals based on their authors’ disciplinary backgrounds. The study combines content analysis of articles with authors’ affiliation analysis. The main research question is: Are authors’ disciplinary backgrounds associated with choice of research topics and methods in LIS articles? The study employs a quantitative content analysis of articles published in 30 + scholarly LIS journals in 2015, focusing on research topics and methods. The articles are also assigned to three disciplinary categories based on authors’ affiliations: External (no authors from LIS institutions), Internal (all authors from LIS institutions), and Mixed (some authors from LIS institutions, some from outside). The association of articles’ disciplinary categories with article research topics and methods is analysed quantitatively. Most research contributions to LIS come from external articles (57%). However, LIS scholars have a clear majority in research on L&I services and institutions (68%), while external scholars dominate the contributions in Information retrieval (73%) and Scientific communication (Scientometrics, 69%). Internal articles tend to have an intermediary’s (29%) or end-user’s (22%) viewpoint on information dissemination while the external ones have developer’s viewpoint (27%) or no dissemination viewpoint (49%). Among research strategies, survey (29%) and concept analysis (23%) dominate internal articles, survey (28%) and citation analysis (19%) dominate mixed articles, and survey (20%) and citation analysis (19%) dominate external articles. The application profiles of research strategies varied somewhat between disciplinary categories and main topics. Consequently, the development of LIS in the areas of Information retrieval, Information seeking, and Scientific communication seems highly dependent on the contribution of other disciplines. As a small discipline, LIS may have difficulties in responding to the challenges of other disciplines interested in research questions in these three areas.

Research disciplinary interactions on scientific collaboration network in photocatalytic hydrogen evolution: Characteristics and dynamics

Interdisciplinary scientific collaboration promotes the innovative development of scientific research. Photocatalytic hydrogen evolution (PHE) is a typical interdisciplinary subject. This study aims to explore the characteristics of discipline interaction and the temporal evolution in the field. Bibliometric analysis could be used to understand the stage of research in a particular subject. In this work, the publications on the topic in Web of Science (WoS) platform from 1999 to 2020 were selected. On the basis of social network theory, the characteristics of interdisciplinary were revealed from three perspectives. First, the disciplinary interaction network is constructed through disciplinary co-occurrence to detect the characteristics of interaction structure among different disciplines. Then the node centrality index is employed to explore the influence of disciplines in the interactive network by using network centrality analysis. Moreover, the dynamic of discipline interaction evolution is studied using blockmodeling analysis. In the field of PHE, the number of disciplines and the intensity of interaction among different subjects gradually increased in the past 20 years. Chemistry and Material Sciences are the core discipline, and they play an important role in the network. The whole network is divided into different discipline groups. The scale of the discipline group is becoming large, and the disciplinary interaction is becoming more complex. The obtained results are helpful for guiding scholars to carry out interdisciplinary interaction. The methods of detecting interdisciplinary interactive relationship could provide paths for interdisciplinary research in other fields.

Cross-disciplinary collaboration versus coexistence in LIS serials: analysis of authorship affiliations in four European countries

The interdisciplinary nature of library and information science (LIS) research has been highlighted for some time now. The term “interdisciplinary” is used primarily in the LIS literature as a general concept with different meanings that refer either to the coexistence of researchers from different scientific fields or to cross-disciplinary collaboration expressed in the form of coauthorship. This study analyses the disciplinary profile of LIS researchers with a view to ascertaining the actual level of cross-disciplinary collaboration and identifying all fields involved. Because of the complexity of identifying accurate affiliations at knowledge area level, the study was limited to authors from France, Germany, Spain and the UK. This analysis of authorship affiliation was performed based on research published in LIS serial titles indexed in Scopus during the 2010–2017 period. A rigorous and laborious process of identifying author affiliations was carried out. This involved checking the authorship of each paper and complementing this with information from websites, scientific social networks and other research endeavours whenever ambiguous situations arose. We observed that LIS departments produce barely a third of the research published in serial titles in the LIS subject category. Cross-disciplinary collaboration among all of the scientific fields involved is low, and even lower in LIS than in other fields. The low level of cross-disciplinary collaboration in LIS contradicts the interdisciplinary nature of LIS highlighted in the literature.
