COPE is just one of a number of organisations that is seeing a large rise in applications for membership from new journals. Although we very much want to encourage and support legitimate new journals, we are also mindful that many new journals are not currently sufficiently transparent about their business practices and authors in particular may be unable to judge the legitimacy of these journals. Together with OASPA, DOAJ, and WAME we have therefore compiled a minimum set of criteria that journals will be assessed against when they apply for membership at one of our organisations. The full criteria can be seen here and we welcome feedback. We encourage authors and anyone else who is unfamiliar with a journal to use these criteria in assessing a journal.
