BioRxiv owned by Cold Spring Harbor Laboratory
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 It is hosted by the Cold Spring Harbor Laboratory (CSHL).As preprints, papers hosted on bioRxiv are not peer-reviewed, but undergo basic screening and checked against plagiarism.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.History
BioRxiv was inspired by and intends to complement the arXiv repository, which mostly focuses on mathematics, physics and connected disciplines, launched in 1991 by Paul Ginsparg (who also serves on the bioRxiv advisory board). It received support from both the CSHL and the Lourie Foundation. Additional funding from the Chan Zuckerberg Initiative was confirmed in April 2017.Prior to the establishment of bioRxiv, biological scientists were divided on the issue of having a dedicated preprint open-access repository. Many had concerns of having their research scooped by competitors and losing their claim to discovery. However, several geneticists had submitted papers to the "quantitative biology" section of the arXiv repository (launched in 2003) and no longer had those concerns, as they could point to preprints to support their claims of discovery.
