OpenDOAR Directory of Open Access Repositories

This database is freely available to the general public via the internet.

OpenDOAR is an authoritative directory of academic open access repositories. Each of these repositories collects, preserves and disseminates the intellectual output of an institution via the internet. Materials in a given repository can contain virtually any electronic file including article preprints and postprints; theses and dissertations; course notes; data and image collections; technical reports; and working documents. Note that the UB Institutional Repository (UBIR), managed by the University Libraries, is listed.

To search for content across multiple open access repositories, try CORE.

There is a browseable list of repositories arranged by regions and countries. You can also search OpenDOAR by repository name.
