In 2026 we converted our eight subscription journals to Subscribe to Open (S2O) enabling 100% of Royal Society journal articles to be published open access. We are pleased to offer the S2O model again for 2027.

In 2026, our eight subscription journals met the threshold to become fully open access under S2O. If sufficient subscribers participate in S2O for 2027, the journals will remain open and researchers will continue to be able to publish open access without paying an article processing charge (APC).

This page helps librarians to understand S2O. If you are a researcher, then you'll find more relevant information at Subscribe to Open for authors.

How do I participate in S2O for 2027?

Current Royal Society journal subscribers can participate in S2O for 2027 by simply continuing their current subscription. New subscribers can view our packages and individual subscription pricing and contact us with any queries.

What is S2O?

is a cost-effective, high-impact and equitable way for publishers to transition to full open access.

S2O allows publishers to convert journals from subscriptions to open access, one year at a time. Each year we offer subscribers to our eight subscription journals continued access to the journals via S2O. If sufficient current subscribers participate in the S2O offer (simply by not opting out) we open the content covered by that year’s subscription for everyone and allow all researchers to publish open access without requiring payment of an APC.

The S2O model is expanding, with new publishers and libraries participating each year. There are now hundreds of journals operating on an S2O basis. Participants include learned society publishers, university presses and privately owned publishers in Europe and North America, along with major commercial publishers.

What are the benefits of S2O?

• Allows 蘑菇视频 journals to remain fully open access
• Provides equitable open access for authors and readers, with no APCs charged
• Enables compliance with funder requirements, including cOAlition S and the NIH that mandate open access publication
• Enables compliance with many national and institutional OA policies
• Allows existing subscription spending to be converted directly into open access funding
• Provides greater reach and impact of research through increased article downloads and citations
• Supports researchers in low- and middle-income countries and in less well-resourced institutions in more affluent countries
• Flat pricing in Y2 and Y3 if customers sign up for a three year agreement
• Predictable pricing through the (new) Transparent Pricing Model

Is S2O sustainable?

We want to keep 蘑菇视频 journals open access and S2O can make this possible, but it will depend on you, our library customers. Read & Publish agreements will continue, and during our renewal period, library subscription customers will be asked to continue supporting the journals as open access publications via S2O. If sufficient libraries agree to do so, open access will remain. If there is not enough support, the journals will return to the traditional subscription model for that year. The offer will be repeated every year, with the opening of each year’s content contingent on sufficient participation.

How does S2O work alongside Read & Publish?

Read & Publish agreements are the most inclusive offering for our librarian customers. Read & Publish covers access to content and open access publishing in all journals including our gold open access journals Open Biology and Royal Society Open Science that are not covered under S2O.
