DOAJ contains more than 10,000 open access journals covering all areas of science, technology, medicine, social science and humanities. During 2015, over 9,000 journals already indexed in DOAJ were required to re-apply to be included. This was to ensure high standards for the journals listed and provide a much-needed filter against questionable, unethical and non-transparent publishing practices.
