Open educational resources (OER) are materials used to support education that may be freely accessed, reused, modified and shared. These Guidelines outline key issues and make suggestions for integrating OER into higher education. Their purpose is to encourage decision makers in governments and institutions to invest in the systematic production, adaptation and use of OER and to bring them into the mainstream of higher education in order to improve the quality of curricula and teaching and to reduce costs. // French version accessible at http://hdl.handle.net/11599/610
