Royal Society in the UK Adopts 'Subscribe to Open' Publishing Model

The UK Royal Society is transitioning eight of its journals to the 'subscribe to open' (S2O) model, which makes content freely accessible if enough libraries subscribe, aiming for 100% open access. This move aligns with a broader trend among scientific publishers adopting the S2O model to promote open access, with varying degrees of sustainability depending on subscription levels and financial support from scientific societies.
