Open access journals are not by definition lower quality than subscription-based journals. Peter Suber says it best: "OA journals can use the same peer review procedures, the same standards, and even the same people as toll access (TA) journals. This isn't hypothetical, and actually happens whenever established TA journals convert to OA. The key variables in journal quality are the quality of authors, the quality of editors, and the quality of referees, all of which are independent of the journal's price or medium.
Search in the relevant department or cluster's tab as well to find subject specific journals.
“Predatory journals and publishers are entities that prioritize self-interest at the expense of scholarship and are characterized by false or misleading information, deviation from best editorial and publication practices, a lack of transparency, and/or the use of aggressive and indiscriminate solicitation practices.”
