Directory of Open Access JournalsDatabase of open access journals covering all scientific and scholarly subjects. Journals can be browsed by title or by broad subject area. Articles are searchable by article author or title, ISSN, journal title, abstract, or key words. Full-text is not searchable but is fully accessible. 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.
