It notes that the number of open access journals has grown significantly, rising from 6,856 journals in 2013 to 42,068 journals in 2020 according to the ISSN International Centre. However, this growth has been accompanied by the emergence of questionable publications, as seen in a $50 million lawsuit against an open access publisher.
