Royal Society Journals Achieve Full Open Access in 2026 via Subscribe to Open Model
The Royal Society confirmed in February 2026 that its eight subscription journals would publish all new content as open access throughout the year, thanks to sustained library support for the Subscribe to Open initiative. This development marks the completion of a multi-year effort that began with a 2021 commitment to reach 100 percent open access by 2026.
Philosophical Transactions of the Royal Society and Proceedings of the Royal Society stand among the titles affected, alongside Biology Letters, Interface, Interface Focus, Proceedings of the Royal Society A, Proceedings of the Royal Society B, and Journal of the Royal Society Interface. All articles appearing in these journals for 2026 carry a CC-BY license and incur no article processing charges for authors when the subscription threshold is met.
Understanding Subscribe to Open and Its Mechanics
Subscribe to Open operates as a collective funding model in which libraries continue their existing subscription payments. When enough institutions participate, the publisher converts the entire journal volume to open access for that year. If the participation target falls short, content remains behind the subscription paywall. The Royal Society reported that its eight hybrid journals met the required threshold for 2026, triggering the full transition.
The process begins with libraries renewing subscriptions under the S2O terms. Revenue from these renewals replaces traditional article processing charges. Corresponding authors affiliated with participating institutions automatically receive a 100 percent discount on any applicable fees. This structure preserves revenue stability for the publisher while removing financial barriers for both readers and authors.
Timeline of the Royal Society’s Open Access Journey
In 2021 the Royal Society set an internal target of full open access by 2026. Two gold open access titles, Royal Society Open Science and Open Biology, already operated under that model. Biographical Memoirs shifted to diamond open access in 2022. The hybrid portfolio required a different pathway, which Subscribe to Open provided after plans were formalized in July 2025 and publicly announced in August 2025.
Confirmation arrived on 16 February 2026 that library participation had secured the transition. An April 2026 blog post from Royal Society Publishing reaffirmed that the goal had been reached and noted that open access output across research journals exceeded 70 percent in 2025, laying groundwork for the complete shift.
Benefits for Researchers and Global Readership
Researchers gain immediate, free access to new findings without institutional subscriptions or pay-per-view fees. Authors publishing in the eight S2O journals during 2026 avoid article processing charges entirely when affiliated with supporting libraries or through the Royal Society’s existing waiver programs for low- and middle-income countries.
Early-career scholars and those at institutions with limited budgets particularly benefit, as the model removes one of the most cited obstacles to open access publishing. The CC-BY license further enables text and data mining, translation, and reuse in teaching materials worldwide.
Implications for Libraries and Consortia
Academic libraries maintain their subscription budgets while achieving broader access for their communities. The model rewards continued participation with expanded readership and eliminates the need for individual article-level payments. Multi-year agreements with consortia help stabilize planning for both publishers and subscribers.
International participation remains essential. The Royal Society has indicated it will repeat the S2O offer in future years, adjusting thresholds based on feedback from libraries and consortia across regions.
Comparison with Other Open Access Approaches
Unlike gold open access, which relies on article processing charges paid by authors or their funders, Subscribe to Open keeps costs within existing library subscription lines. Diamond open access, used by Biographical Memoirs, covers expenses through sponsorships or institutional support without author fees. Transformative agreements blend read access with open access publishing rights, yet Subscribe to Open offers a simpler annual on-off switch tied directly to collective library commitment.
Similar models have succeeded with other publishers, demonstrating that sustained subscription revenue can underwrite full open access when participation reaches critical mass.
Stakeholder Perspectives Across Academia
Library leaders highlight predictable costs and expanded access as primary advantages. Researchers emphasize the removal of paywalls and fees as steps toward more equitable knowledge sharing. Publishers note that the model supports editorial quality and peer review infrastructure without shifting expenses to individual authors.
Early observations from 2026 indicate increased submissions and downloads in participating journals, consistent with patterns seen in prior open access transitions. Monitoring continues throughout the year to assess long-term effects on citation rates and research visibility.
Challenges and Sustainability Considerations
Maintaining the participation threshold each year requires ongoing engagement with libraries facing their own budget pressures. Some institutions may question whether continued subscription payments deliver sufficient return when content becomes openly available. The Royal Society has committed to transparent reporting on participation levels and usage metrics.
Global equity remains a focus. Waiver programs for researchers in low- and middle-income countries continue alongside the S2O model, ensuring that authors outside participating library networks are not disadvantaged.

Future Outlook for Academic Publishing
The Royal Society’s transition provides a case study for other learned societies considering similar shifts. Success depends on collective action by libraries, yet it demonstrates a viable route that avoids the author-pays model dominant in many gold open access journals.
Observers expect further experimentation with Subscribe to Open and related collective models in 2027 and beyond. The approach aligns with broader calls for sustainable open access that preserves publisher revenue while maximizing public access to publicly funded research.
Practical Steps for Authors and Institutions
Researchers planning submissions should verify institutional participation through their library or directly with the Royal Society. Corresponding authors at supporting institutions receive automatic fee waivers for 2026 publications. Those at non-participating institutions may still qualify for waivers under existing low- and middle-income country provisions.
Institutions considering S2O support can review the Royal Society’s librarian resources for renewal details and participation thresholds. Multi-year commitments help both parties plan with greater certainty.
