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. 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.
