Bibliographical noteFunding Information:
This list does not include institutional repositories, which often host self-archived preprints. • arXiv. Initially the server was hosted at LANL and was limited to physics research but now includes several other disciplines, including mathematics, computer science, quantitative biology, quantitative finance, statistics, electrical engineering and systems science, and economics. arXiv was created by Paul Ginsparg in 1991, and in 2001 Gin-sparg and the repository moved to Cornell University. arXiv is considered a trailblazer for electronic preprints. It is currently funded by Cornell University, the Simons Foundation, and contributions from 233 member institutions. Access: https://arxiv.org. • bioRxiv. Launched in 2013, this repository contains research from the life sciences and is maintained by Cold Spring Harbor Lab-oratory (CHSL). bioRxiv facilitates direct transfer of submissions to participating journals. This means authors are able to submit manuscripts to participating journals by transmitting files as well as metadata, from the bioRxiv platform. They refer to this as “B2J.” Access: www.biorxiv.org. • ChemRxiv. The scope of this preprint repository is chemistry and related fields. It is a collaborative initiative including the following groups: the American Chemical Society, the German Chemical Society, and the Royal Society of Chemistry. Access: https:// chemrxiv.org. • MedRxiv. Launched in June 2019, this health sciences preprint server is a collaborative effort between CSHL, BMJ, and Yale. Submissions are screened to deter po-tential risk to public health.
