The Directory of Open Access Journals (DOAJ) is the primary source for identifying open access journals:
- DOAJ is a database of open access journals covering all scientific and scholarly subjects.
- Primarily used to identify open access journal titles (and forty percent of them are searchable at the article level)
- Journals can be browsed by title or by broad subject area.
- To be included in the DOAJ, journals must use a funding model that does not charge readers or their institutions for access and must exercise peer-review or editorial quality control.
- DOAJ is therefore regarded as a gatekeeper – ensures that journals are legitimate in terms of business model and provision of access to journal articles.
