ChemRxiv (pronounced "chem archive"—the X represents the Greek letter chi [χ]) is an open access preprint archive for chemistry. It is operated by the American Chemical Society, Royal Society of Chemistry and German Chemical Society. The new preprint server was announced already in 2016, but was only opened online in 2017. Initially, editors of ACS journals were skeptical and only 80% of the editors allowed submissions to be uploaded to the preprint server in 2017. In 2019 the Chinese Chemical Society and the Chemical Society of Japan joined as co-owners of the preprint server. More information...
