Björk B. Solomon D. Pricing principles used by scholarly open access publishers. Learned Publishing 2012;25(2):132-137
The article processing charge (APC) is currently the primary method of funding professionally open access (OA) peer reviewed journals. In the article the pricing principles of 77 OA publishers publishing over 1,000 journals using APCs were studied and classified. The most common pricing method is a single fixed fee, that can be either the same for all of a publisher's journals or individually determined for each journal. Among the big OA publishers, the individual journal pricing seems to be the dominant mode.
