Based on the philosophy of open access coined by the philosopher, professor, and researcher Peter Suber, the homonymous initiative aims to promote the availability of didactic literature at no cost, allowing any user to read, download, copy, distribute, print, and link the full text of the articles they access. The use of these materials is entirely free as long as it is correctly referenced and indexed. Open Educational Resources (OER) are the pillar of the universal right to education and pursuit of peace, proclaims UNESCO. The Education Division of this non-governmental organization (NGO) focuses on monitoring and analyzing global progress in adopting the open-access philosophy and resources and developing and disseminating policies.
