This paper is intended as a starting point for discussion on the possible future of scientific communication in chemistry, the value of new models of scientific communication enabled by web based technologies, and the necessary future steps to achieve the benefits of those new models. It is informed by a NSF sponsored workshop that was held on October 23-24, 2008 in Washington D.C. It provides an overview on the chemical communication system in chemistry and describes efforts to enhance scientific communication by introducing new web-based models of scientific communication. It observes that such innovations are still embryonic and have not yet found broad adoption and acceptance by the chemical community. The paper proceeds to analyze the reasons for this by identifying specific characteristics of the chemistry domain that relate to its research practices and socio-economic organization. It hypothesizes how these may influence communication practices, and produce resistance to changes of the current system similar to those that have been successfully deployed in other sciences and which have been proposed by pioneers within chemistry.
