Our contemporaneous society embodies a complex and fast process of democratization of capacities for the access, publication and sharing of scientific information and knowledge that became explicit in the second half of the twenty century and more accentuated since its sixties with the emergence and consolidation of the Internet and the Web as an universal, innovative and dominant media for content storage, access and communication. Developing countries have incorporated themselves in this process with barriers that impede, limit or retard the democratization of the access and publication in their interior as well as in their integration in the global flow of information, in a large extent due to inherent difficulties and limitations for the adoption of solutions that presuppose conditions and infrastructures typically from the market of developed countries. The plenty informational integration of the developing countries in the global flows demand solutions and modus operandi that enable infrastructures capa ble to sustain and progress with foundations and characteristics based on collaborative net-work in the production of information sources and flows as local, national, regional and global public goods. In this presentation we will analyze some of these foundations solutions and modus operandi from Latin American and Caribbean with sound results in the contexts of the Virtual Health Library (VHL) and Scientific Electronic Library Online (SciELO), which emerge as innovative models of cooperation of the south for the informational integration of research, educational and healthcare systems.
