medRxiv.org - the preprint server for Health Sciences

"medRxiv (pronounced "med-archive") is a free online archive and distribution server for complete but unpublished manuscripts (preprints) in the medical, clinical, and related health sciences. Preprints are preliminary reports of work that have not been peer-reviewed. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.

medRxiv was founded by Cold Spring Harbor Laboratory (CSHL), a not-for-profit research and educational institution, Yale University, and BMJ, a global healthcare knowledge provider. The server is owned and operated by CSHL. medRxiv provides a platform for researchers to share, comment, and receive feedback on their work prior to journal publication. medRxiv aims to improve the openness and accessibility of scientific findings, enhance collaboration among researchers, document provenance of ideas, and inform ongoing and planned research through more timely reporting of completed research. medRxiv is a non-profit community resource and is not linked to any one publisher or journal...."
