OpenDOAR — Directory of Open Access Repositories
Overview
OpenDOAR is a global, quality-assured directory of open access repositories covering academic institutions in more than 130 countries, operated by Jisc and originating from a collaboration between the University of Nottingham and Lund University in 2005. It indexes institutional, subject-based, and governmental repositories that provide free, unrestricted access to academic outputs including articles, theses, datasets, and other scholarly content. Each repository record describes content types, subjects, software, and the host organisation. OpenDOAR is the standard reference used by funders and publishers to verify that a repository constitutes a compliant open access deposit route, making it a practical checkpoint in cOAlition S and Plan S compliance workflows.
