Since the release of the ChemRxiv beta version in 2017, the support and usage of the free archive service for unpublished preprints in chemistry has increased tremendously. Since August 2019 the Chinese Chemical Society and the Chemical Society of Japan became co-owners of ChemRxiv, joining the founding societies the American Chemical Society, the Royal Society of Chemistry, and the German Chemical Society.

Just recently the 10.000^th preprint article has been uploaded to the archive. The most prevalent topics include:

• computational chemistry (2911 entries)
• organic chemistry (2142 entries)
• physical chemistry (2139 enties)

and many more…

Here are some useful tips in case you want to submit your preprint!
