PREreview is celebrating Peer Review Week 2026 with a global Review-a-thon, where Clubs review together preprints and datasets in any field or language. The goal is to showcase the transformative power of human, collaborative peer review in the research evaluation culture.

For underserved researchers, there’s a better way

We support and empower diverse and historically excluded communities of researchers (particularly those at early stages of their career) to find a voice, train, and engage in peer review.
