Please add bioRxiv https://www.biorxiv.org/ to Primo Central
bioRxiv (pronounced "bio-archive") is a free online archive and distribution service for unpublished preprints in the life sciences. It is operated by Cold Spring Harbor Laboratory, a not-for-profit research and educational institution. By posting preprints on bioRxiv, authors are able to make their findings immediately available to the scientific community and receive feedback on draft manuscripts before they are submitted to journals.
Gary Kaplan commented
This is an important addition. BioRxiv is responsible for much of the large growth of preprints in the biological sciences over the past few years. (See Jordan Anaya‘s chart, included in “The Stars Are Aligning for Preprints” https://scholarlykitchen.sspnet.org/2017/04/18/stars-aligning-preprints/)
