The SciELO Program is implemented through the 20 years old SciELO Network composed by 15 national collections of open access peer reviewed journals from Latin American countries, Portugal, Spain and South Africa. Through its three main lines of actions known as Professionalization, Internationalization and Finantial Sustainability, SciELO aims to improve quality, visibility and credibility of nationally edited journals of developing countries and the research they communicate.
