Subscribe to Open - Karger Publishers

"In 2023, we will be piloting the Subscribe to Open (S2O) business model with two journals, Pediatric Neurosurgery and Developmental Neuroscience, as part of our ongoing drive to support the transition to Open Access (OA). S2O is a alternative way to move journals to OA, alleviating some of the challenges that come with Gold OA. Where Gold OA relies on payment for publishing in the form of Article Processing Charges (APCs) by the authors or their institutions, S2O makes use of the existing subscription base, funds and infrastructure to make journals free to read and share as well as to publish in. Unlike Gold OA journals, which are continually OA, the OA status of S2O journals is decided volume by volume, early every year (depending on the level of subscriptions). S2O was originally developed by the publisher Annual Reviews and has been adopted by a growing number of publishers who are collaborating in the S2O Community of Practice...."
