Open Access Library (OALib) is an open-access scholarly search platform and journal repository that aggregates millions of research articles across science, engineering, medicine, social sciences, and humanities. Designed to improve global access to academic knowledge, OALib offers free full-text search, article hosting, and its own open-access journal, OALib Journal, which publishes multidisciplinary research. While the platform provides broad coverage and easy accessibility, it is more of a general-purpose aggregator compared to established databases like PubMed, arXiv, or Directory of Open Access Journals (DOAJ). Still, OALib serves as a useful discovery tool—especially for researchers, students, and independent scholars seeking freely available literature without paywalls.
