BioRxiv is a free online archive and distribution service for unpublished preprints in the life sciences. It is launched by Cold Spring Harbor Laboratory Press in New York, a not-for-profit research and educational institution. It operates similarly to arXiv, with scientists depositing papers as soon as they are ready to share them, weeks or months before their publication. By posting preprints on bioRxiv, authors are able to make their findings immediately available to the scientific community and receive feedback on draft manuscripts before they are submitted to journals. This website leaves journals divided, with many of them that have changed their policies in recent months to allow the practice.
