Directory of Open Access Journals (DOAJ)
The Directory of Open Access journals (DOAJ) is a community-curated directory. It indexes high-quality Open Access journals with Peer Review procedures worldwide and makes them accessible. This database can serve as a good source for the search for reliable, quality-checked Open Access journals. Official recognition as an Open Access journal by the DOAJ, particularly if the DOAJ seal is received, guarantees the high quality of an Open Access journal. In the DOAJ, you can see if a journal demands the payment of an APC and if so, how high it is. A filter enables authors to search only for journals where the authors retain all rights.
Searching in the DOAJ for the name of a journal can also help to identify predatory journals, because this white list contains only Open Access journals that have undergone an adequate quality assurance procedure.
