Currently 749 journals are searchable at article level. As of today 124596 articles are included in the DOAJ service.

 

OpenDOAR

Users of this service can search through the world's repositories of freely available research information, with the assurance that each of these repositories has been assessed by OpenDOAR staff. This quality controlled approach will minimise (but not eliminate!) spurious or junk results, and lead more directly to useful and relevant information.
