bioRxiv is an open access preprint repository for the biological sciences
As preprints, papers hosted on bioRxiv are not peer-reviewed, but undergo basic screening and checked against plagiarism. Readers may offer comments on the preprint. It was inspired by and intends to complement the arXiv repository, which mostly focuses on physics and connected disciplines, launched in 1991 by Paul Ginsparg. It received support from both the CSHL and the Lourie Foundation. A service called Rxivist combines preprints from bioRxiv with data from Twitter to rank pre-prints.
