Mapping of Life Science Journals in DOAJ: A Scientometric Study (2021–2025)

Open access (OA) publishing plays a vital role in disseminating research globally, particularly in the life sciences. The Directory of Open Access Journals (DOAJ) is among the largest curated indexes of peer-reviewed OA journals, hosting over 22,000 journals and 12+ million article records across disciplines including life sciences. This study maps the life science journal landscape in DOAJ from 2021 to 2025, analyzing subject distribution, publication output trends (volumes and issues), authorship patterns, geographical distribution of journals and authors, and other scientometric indicators. The article also discusses journal indexing features and highlights representative high-impact DOAJ life science journals. Recommendations for future DOI-level and API-driven studies are provided.
