OpenDOAR is an authoritative directory of academic open access repositories. Each OpenDOAR repository has been visited by project staff to check the information that is recorded here. This in-depth approach does not rely on automated analysis and gives a quality-controlled list of repositories.
Typically OpenDOAR lists publication repositories, as this is the basis for most repositories. However, OpenDOAR also lists other types, for example of images or data-sets, particularly where these have metadata or documentation sufficient to make the material re-usable.
Note that repositories listed in OpenDOAR are not necessarily OAI-PMH compliant. OAI-PMH is widely used for facilitating search of open access materials, but use of OAI-PMH is not synonymous with open access itself.
Common reasons for not listing a site in OpenDOAR include (but are not limited to):
- Site is repeatedly inaccessible
- Site is an eJournal (Open Access or otherwise - See DOAJ)
- Site contains no Open Access materials
- Site contains metadata (bibliographic) references only or solely links to external sites
- Site is actually a library catalogue or collection of locally accessible e-books
- Site requires login to access any material (gated access) - even if freely offered
- Site is a proprietary database or journal that requires a subscription to access
OpenDOAR is one of the SHERPA Services including RoMEO and JULIET, run by the Centre for Research Communcations (CRC).
