Preprints

A preprint is a version of a scientific manuscript posted to a public server prior to peer review or formal publication in a scholarly journal. PLOS empowers authors to post preprints as a way to accelerate the dissemination of their research.

Authors are strongly encouraged to share their research on a preprint server and to provide links to their preprint during submission, and editors are advised to use comments posted on preprints and preprint reviews where applicable. Additionally, preprints on bioRxiv and medRxiv can be directly transferred to a relevant PLOS journal for a streamlined submission process.

PLOS makes the interaction between preprint servers and our journals as easy as possible, and we link our publications to the relevant preprint for authors.

There are many active preprint servers; see the Open Science Foundation’s preprint archive search for a list. Some servers accept preprints from any research field but many are specific to geographical regions or research disciplines.

Concerns

If a concern arises about a published PLOS article with a related preprint, PLOS will evaluate the concern according to our standard editorial processes, taking into account any relevant comments available on the preprint.
