Nature Publishing Group and the Alliance for Cellular Signaling formed a partnership in 2001 to develop a comprehensive website for researchers in the field of cellular signalling. This website aimed to evolve the traditional form of publication (an article with supplementary information and links) into something that made better use of web and database technologies, and provided more value to scientists. This article gives an overview of the project, some of the thinking behind it, and how it has developed.
