In November 2019, UNESCO adopted a recommendation on Open Educational Resources (OER). This recommendation, a result of a consensus among 193 Member States, recognises the importance of supporting the development, sharing and use of openly licenced educational materials to improve access to education for all. Libraries, as a driving force in educational issues through their missions of access to information and education, have a role to play in fostering the development of OER and thus in advancing this work.
