These Guidelines for implementing open access policies have been produced by the EC-funded project “Mediterranean Open Access Network”. They aim at coordinating policy-development in six Mediterranean countries that participate in the project by providing concise and targeted guidelines for a harmonized approach towards policy development. They are directed to policy-makers and policy stakeholders specifically, to Research Performing Organizations and Research Funders. The guidelines take into consideration best practices and recent policy developments, in particular the European Commission’s Recommendation and Communication on access to and preservation of and dissemination of scientific information (2012) and the planning for Horizon 2020. They are also informed by relevant documents, policy papers, recommendations and guidelines, produced recently by organizations such as UNESCO, The League of European Research Universities, the European University Association, Science Europe, among others, as well as by surveys performed in the six countries by the project.
