Now, a LERU working group has compiled a "Roadmap towards Open Access". Through this document, the organization hopes to guide universities by giving clear-cut advice on how to achieve open access to research.
The paper describes both "Green route" repositories and "Gold route" journals and steps towards their implementation. This is accompanied by a list of examples and supporting organizations and cost estimates. A survey of UK repositories for instance indicates that the Green route costs between €30,000 and €242,000 annually.
