DOAJ
A directory of vetted open-access journals together with article-level metadata, covering roughly 21,000 journals and over 10 million articles. Searches run through a keyless interface over its openly licensed metadata, or you can browse the site directly. Use it to confirm a journal is genuinely open access or to find freely readable articles.
Son utilité et son fonctionnement
DOAJ is the most trusted directory of genuine open-access journals: its editorial team vets every journal for quality, so a listing here is a signal that an article is freely available and legitimately peer-reviewed. You can search article-level metadata to find a paper, or look up a journal title to confirm it is truly open access. Echo queries DOAJ's openly licensed metadata API, which requires no key and covers every discipline.
