Modelo conceptual para la automatización de bibliotecas en el contexto digital

Abstract

The role of information technology as a critical agent of change in public library information services, in the environment of infornation society, is studied, considering the redefinition of libraries social functions and services. First of all, it's presents a terminological survey of modern libraries trends (digital library, electronic library, virtual library, hybrid library). Hybrid library is selected as a valid conceptual framework for this work: library services in digital context. Library automation and technologies concepts and applications are reviewed, focusing in library systems, which match into a classic model of library automation. Information retrieval and public information features (Opac) are studied in-depth, in order to compare it with recent development in the information market for libraries and significant digital ibraries projects. The strategic role of information technologies management is presented as a requirement for understanding the complex interrelation between services and technologies. It's also analysed the two technological context that have a greater potential of influence in library systems: In one hand the Groupware and Workflow, and in the aher hand internet virtual communities and portals. Also is described the different points of view about digital information systems architecture, introducing the concept of Net-Library, as an organizational view of libraries in interaction inside an infomation and social environment. A new conceptual framework of library systems is defined, with extended functionalities derived of social and technological changes about information services, denominated Extended Library System. It's structured in two leve ls: application and product. The first level describes the modules of an library management and infonnation system application. The second one is dedicated to fue public information project requirements of a library portal. Finally it presents structured indicators to evaluate extended automation, as well as elements to model hybrid libraries information technologies project
