The SciX (Open, self organising repository for scientific information exchange) project is funded by the European Commission in order to demonstrate the feasibility of new alternative models of scientific publishing made possible by the Internet. The project builds upon the previous experience of some of the partners in running an electronic peer reviewed journal and in setting up an e-prints archive. The project includes both theoretical work in making a formal model of the scientific publishing process, to be used as a basis for studying the life-cycle costs of alternative business models, and a demonstrator of a functioning e-prints archive.
