> **bioRxiv** (pronounced "bio-archive") is an open access preprint repository for the biological sciences co-founded by John Inglis and Richard Sever in November 2013. It is hosted by the Cold Spring Harbor Laboratory (CSHL).As preprints, papers hosted on bioRxiv are not peer-reviewed, but undergo basic screening and checked against plagiarism. However, peer reviews from other sources may be posted alongside preprints. Moreover, readers may post comments. > > It has been measured that two thirds of the papers posted in bioRxiv are later published in peer-reviewed journals. BioRxiv, and its sister site, medRxiv, have been major sources for the dissemination of [[Covid-19]] research. > > [Wikipedia](https://en.wikipedia.org/wiki/BioRxiv)
