The right way forward for science

Not all preprint venues are truly open-access. In contrast, PeerJ PrePrints is fully CC-BY, meaning you don't need to worry about sharing or reusing articles you find. Everyone benefits. Learn more about CC-BY.

Rapid scientific communication & early findings

A PeerJ 'PrePrint' is a draft that has not yet been peer reviewed for formal publication. Similar to preprint servers that already exist (for example arXiv.org), authors can submit draft, incomplete, or final versions of articles they are working on.

By using this service, authors establish precedent; they can solicit feedback, and they can work on revisions of their manuscript. Once they are ready, they can submit their PrePrint manuscript into the peer reviewed PeerJ journal (although it is not a requirement to do so).

Submissions today can be approved by editorial staff and online within 24 hours.
