The journal matching feature suggests the top candidates for your manuscript. Just choose the publications you want, and start the process for submitting your work to the most credible, high-quality journals that match your topic and references.
DOAJ is a community-curated online directory that indexes and provides access to high quality, open access, peer-reviewed journals. Look for journals with the green tick mark or the orange DOAJ seal of approval for indications that the journal has been vetted.
This database is useful for determining whether or not a journal is peer-reviewed/refereed. Simply enter the name of the journal and look for the Referee Jersey icon. If you see it, it is registered with the directory as peer reviewed. (Keep in mind that Ulrich's is a directory and does not necessarily evaluate the validity of the journal.)
