Tarin Gamberini wrote another monitoring report about PDFreaders in Italy: "Adoption of Free Software PDF readers in Italian Regional Public Administrations (fifth monitoring)"

The following monitoring shows that, in the last semester, eight Italian Regions have reduced advertisement of proprietary PDF readers on their website, and that a Region has increased its support for Free Software PDF readers.
