OpenDOAR is an authoritative directory of academic open access repositories. Contain digital collections that preserve and provide access of intellectual output of an institution, and content varies i.e. could be open or closed, though open is encouraged today.Each OpenDOAR repository has been visited by project staff to check the information that is recorded there. This in-depth approach does not rely on automated analysis and gives a quality-controlled list of repositories.
As well as providing a simple repository list, OpenDOAR lets you search for repositories or search repository contents
