There are plenty of so-called predatory journals out there. The libarian Beall (famous for his list of predatory journals) explains it all to you in a Q&A with helpful links at the Chronicle of Higher Education Brainstorm Blog.
Compare it with the opposite end of the world of publishing, the ERC gate-keeping initiative ERIH, listing approved journals only (for Humanities and Social Sciences, formerly ranked, but now not anymore).
But some good journals might not be listed at the ERIH and wrongly listed as predatory journal. A critical stance and common sense, together with some critical thoughts and recommendations from Declan Butler will help you through the jungle.
