All Journal titles published by Pluto Journals are free of author charges. This means that authors are not charged any submission fees, editorial processing charges, article processing charges (APCs) or any other charge during any point from submission to publication.

The “Subscribe to Open” (S2O) model converts subscription journals to Open Access without reliance on either article processing charges (APCs) or altruism.

S2O relies on existing library subscription procurement processes. The model provides a realistic and immediate route to opening a vast body of research output that would otherwise remain gated.
