摘要：As pressures mount from global funding mandates and initiatives like Plan S, publishers are seeking sustainable solutions to transition their subscription portfolios to open access. For self-publishing societies with niche portfolios and low publication volumes, traditional transition options such as article processing charge models or transformative agreements are limited or out of reach and often involve significant financial risk. In this article, we focus on one society publisher’s implementation of Subscribe to Open (S2O): an emerging open access model that moves away from article-level charges, instead leveraging existing subscription revenues and infrastructure to achieve seamless and sustainable open access. We outline the advantages of this model for society publishers, the parameters to consider when implementing the model, the initial community response to a successful implementation and some early data highlighting the effect of the S2O model on our journals.
