Publishers typically charge fees (APCs, Article Processing Charges) for publication in Open Access journals, which must be paid by the authors or their institutions.
Also so-called page charges for the publication of articles with excess length and license fees for the subsequent use of illustrations, articles or the like (e.g. at the Copyright Clearance Center CCC) are subject to publication fees.
The Directory of Open Access Journals (DOAJ) lists high-quality Gold and Platinum Open Access journals. Gold OA-Journals are financed by APCs, Platinum OA-Journals do not charge APCs to authors nor subscription fees to libraries or users. They are financed by membership fees, donations or sponsorship.
