Chemistry preprint servers (revisited).

Key Points

• The ACS has announced a new chemRxiv preprint server to enhance early research sharing in chemistry.
• Previous attempts at a preprint server attracted few submissions, revealing challenges in quality and engagement.
• The initiative echoes practices in physics, which have effectively utilized preprint servers for sharing research.
• The success of this server may depend on factors such as submission rates and the resulting quality of shared research.
