<abstract xmlns="http://eprints.org/ep2/data/2.0">The research publications funded with public moneey must be open access following the BOAI (Budapest Open Access Initiative) and the Berlin Declaration. Authors can self-archive their articles into institutional or disciplinary repositories, being aware that not all the publishers allow to do so. Authors, then, must learn to retain economic exploitation for themselves, leaving to publishers the rights to publish only.</abstract>
