Integrating sciences health library network for the sustainable development of regional health library

The library systems in the modern era are the critical link to link on a common purpose to individuals and institutions that manage information and knowledge in a particular subject area. These systems are themselves social and open systems, are based on activities that complement and interact in space and time. The paper describes in detail the elements of network science libraries in Cuba health and how each one contributes greatly to the life cycle of information in medical libraries. Combine in a triad activity of "Traditional Library" with the "Health Library" and the use of technology to support the development of information management in each model. We propose a flow that links the document management, information management and knowledge management from INFOMED to the library network and vice versa to ensure effectiveness and efficiency of each business process and the development of a smart grid where all members form true communities of practice that integrate information and knowledge to the Virtual Health Library Latin American and Caribbean (NLM).
