See our many PREreview Clubs

PREreview celebrated Peer Review Week 2026 with a global Review-a-thon to showcase the transformative power of human, collaborative peer review in the research evaluation culture. 14 PREreview Clubs joined the initiative to review preprints in 4 different languages and on multiple research topics.

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.
