Today, we published our 2025 Annual Report, sharing our achievements from last year and renewing our commitment to work in collaboration with you to shape an equitable, open, and transparent scholarly evaluation landscape.
In 2025, we built our annual strategic approach to advance our mission around three key objectives:
- Ensure sustainability of resources and growth of organization
- Increase diversity of PREreview's community through accessibility and inclusion
- Increase PREreview's organizational and technical presence in innovative spaces
Find out how we made great progress in all these areas:
A Year of Collective Resolve and Growing Momentum
The past year unfolded amid profound global instability, direct threats to science and equity, and ongoing challenges across the research ecosystem. In response, PREreview took time to reflect, re-center, and publicly reaffirm our shared values and commitment to freeing knowledge. At a moment when power in scholarly publishing is too often concentrated away from researchers and the communities meant to benefit from their work, we continue to challenge the status quo and advocate for more open, community-driven approaches to research evaluation.
Our belief remains simple and one that guides all our work: anyone with relevant knowledge should be empowered to offer feedback that can meaningfully shape the direction of research. In 2025, that belief translated into action through a growing, energized global community. Twenty-three new PREreview Champions joined our network, acting as multipliers by training and supporting nearly 800 community members to adopt open and equitable preprint review practices.
Expanding access was a major focus this year. By translating and localizing PREreview’s websites and resources into Latin American Spanish and Brazilian Portuguese, we saw double- and triple-digit growth across key indicators, including new and total reviews, collaborative reviews, reviews written in response to requests, and the formation of new PREreview clubs. Even as requests for reviews increased dramatically, PREreviewers continued to respond at a steady rate—resulting in substantially more total reviews than in previous years. Growth, importantly, has been collective.
Improvements to PREreview.org and targeted trainings are also lowering barriers for newcomers. A higher proportion of new PREreviewers are now publishing reviews, signaling that community support, platform enhancements, and professional development efforts are working together as intended.
Looking ahead, this momentum positions us to surpass 2,000 PREreviewers and 4,000 published reviews in 2026—an acceleration that reflects the growing uptake of free, open, and equitable infrastructures for evaluating preprints and other early research outputs. As we plan for the future, we remain focused on expanding review workflows, adding new languages, supporting patients, educators, and learners, and strengthening our core infrastructure to better serve our community.
PREreview is honored to work alongside community members, funders, and partners who are helping advance open knowledge for the benefit of all. This annual report is both a reflection of what we’ve accomplished together—and an invitation to continue building what comes next.
