Some 7 years ago, following successes in physics, ChemWeb.com launched the Chemistry Preprint Server (CPS), and Warr evaluated it in a JCIM article three years later. She wrote about ‘lessons learned’, but the only one seemed to have been that chemistry was not ready for it, as the project shutdown in 2004. The archives are still available, fortunately, and you may find it amusing to look up my or some other submission.
