Description:What is the current state of digital repositories for research output in the European Union? What should be the next steps to stimulate an infrastructure for digital repositories at a European level? To address these key questions, an inventory study into the current state of digital repositories for research output in the European Union was carried out as part of the DRIVER Project. The study produces a complete inventory of the state of digital repositories in the 27 countries of the European Union as per 2007 and provides a basis to contemplate the next steps in driving forward an interoperable infrastructure at a European level.
