Directory of Open Access Journals
This service covers free, full text, quality controlled scientific and scholarly journals. We aim to cover all subjects and languages. There are now 2516 journals in the directory. Currently 749 journals are searchable at article level. As of today 124596 articles are included in the DOAJ service.
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 Open DOAR staff. This quality controlled approach will minimize (but not eliminate!) spurious or junk results, and lead more directly to useful and relevant information.
