How to Avoid Predatory Publishers?
Alongside the increasing popularity of legitimate open access publishing, there has also been a rise in what is known as predatory (or questionable) publishing. Predatory publishers solicit and accept manuscripts and fees from authors, but do not provide the editorial and peer review services that are part of legitimate scholarly publishing.* The tools listed below can help you vet the predatory publishers.

DOAJ is an online directory that indexes and provides access to high quality, open access, peer-reviewed journals.
Journals must be vetted according to strict membership criteria before being granted membership in OASPA, so their membership list can serve as a sort of "whitelist" for open-access publications.
