Open Access at CERN - status and visions

The CERN Document Server offers green open access to a large range of the research results produced by the laboratory throughout its five decades of existence. Most of the current output is captured through direct submissions or by harvesting arXiv.org. Even prior to the start of the Open Access movement the Organization had a mandate in place, obliging all collaborators to submit their scientific findings resulting from works carried out using CERN infrastructures. However, several indicators show that the success of the institutional repository is not dependent on any mandate, but simply on the service offered to its users. Strategies for how to achieve complete coverage in an institutional repository will be discussed
