Digital publishing and open access in Library and Information Science (2020–2025): A bibliometric and science-mapping analysis

Purpose: This study maps the intellectual and thematic evolution of research on digital publishing and open access (OA) in Library and Information Science (LIS) between 2020 and 2025, identifying major trends, influential contributors, and emerging frontiers. Methods: A bibliometric and science-mapping analysis was conducted on 1849 publications indexed in the Web of Science Core Collection. Performance indicators captured productivity and citation patterns, while science mapping examined co-authorship, co-citation, and keyword co-occurrence networks. Results: Publications show steady growth, peaking in 2024, with the United States, China, and the United Kingdom as leading contributors. A core–periphery authorship structure is anchored by prolific scholars such as Abrizah A, Xu J, Jamali HR, and Nicholas D. Highly cited works in JASIST, Journal of Academic Librarianship, and Library Hi Tech form the intellectual backbone of the field. Thematic mapping reveals continuity in topics such as academic libraries and scholarly communication, alongside newer themes including artificial intelligence, equity, and open science. COVID-19 temporarily reshaped research dynamics (2020–2022), highlighting the community’s responsiveness to global disruptions. Implications: The study deepens understanding of LIS research dynamics within Web of Science–indexed venues and offers guidance for libraries, policymakers, and publishers. It highlights the need to foster context-sensitive OA models, support more equitable participation in APC-driven environments, and integrate technological innovation into scholarly communication infrastructures.
