Fernanda Ribeiro and Armando Malheiro da Silva, Portuguese archivists, defend a postcustodial paradigm related to analyses of archives on current days too. Unlike the previous period, known for praising custody, patrimony and technicalities regarding Archives and Libraries, the postcustodial paradigm does not depend on physical spaces and institutions created mainly since 1789 along with the administrative changes brought by the French Revolution: a model of institutional keeping and guarding public administration documents has become available for the sake of democratic ideals. Such paradigmatic model is attached to the building, the physical place, which according to Ribeiro was a popular idea fuelled by the positivism.
