Philosophiae Doctor - PhD (Library and Information Studies) / The study examined the availability of e-resources in the Ibrahim Babangida Library at Modibbo Adama University of Technology, Yola (MAUTECH) focusing to integrate e-resources in a dedicated portal for easy access. The study was motivated by the Nigerian vision 20:2020 and the trend in 21st century academic libraries to offer electronic resources and services to meet users? demands and use of technology. Mixed methods were sequential, concurrent, conversion and integrated approaches used. A descriptive case study approach was employed. The Technology Acceptance Model (TAM) and Diffusion of Innovation (DoI) theories framed the study. Based on these, a conceptual framework was constructed. To achieve triangulation, questionnaires, interviews and scanning of library portals were used to gather both quantitative and qualitative data. Academics, students, academic librarians, and information and communication technology experts acted as participants. Findings reflected low use of the Ibrahim Babangida Library, dissatisfaction with the quality and quantity of the library collection, insufficient and unreliable Internet access on campus, limited information literacy education, familiarity and utilization of e-resources due to flexibility and easy access to academic information, need for digitisation of library resources and the need for a dedicated library portal. The study recommends, amongst others, information literacy education for students and academics, subscription to full-text databases, provision of sufficient and free Internet access, e-resource and e-services policies, and establishing a consortium with other Nigerian academic libraries. The outcome of the study was a designed, established and functioning library portal based on the input of all the stakeholders of the MAUTECH community.

Partiendo de un análisis de los principales aspectos de la sociedad de la información como contexto social en el que las bibliotecas actuales redefinen su función social y sus servicios, se estudia el papel de la tecnología como agente de cambio en los servicios de información de las bibliotecas públicas. Antes de estudiar la automatización y las tecnologías en las bibliotecas, se realiza un estudio terminológico sobre la biblioteca actual en este sentido (biblioteca digital, biblioteca electrónica, biblioteca virtual y biblioteca híbrida).La biblioteca híbrida se toma como marco conceptual para el desarrollo del trabajo: el ámbito de los servicios de biblioteca en el contexto digital. Posteriormente se revisa la evolución del concepto y aplicación de la automatización de bibliotecas, centrándose en la descripción de las aplicaciones de gestión integral de bibliotecas (SIGB). Se elabora un esquema común que responde al modelo clásico de automatización de bibliotecas, y de él se estudian con más detalle los elementos pertenecientes al sistema de información público, generalmente conocidos como Opac. Posteriormente se traza un panorama actual del mercado de la información y de aplicaciones para bibliotecas, atendiendo a las divergencias y desarrollos del modelo clásico. Se recoge información sobre los proyectos de bibliotecas digitales más significativos, y se ponen en relación con la gestión estratégica de las tecnologías en las bibliotecas. Se completa este apartado con el estudio de los dos contextos tecnológicos actuales que más inciden sobre las posibilidades y configuración de las aplicaciones de gestión bibliotecaria; por un lado la gestión documental corporativa (Groupware y Workflow) y por otro los portales y comunidades virtuales en internet. Antes de describir nuestra propuesta conceptual de SIGB, se estudia la arquitectura del sistema de información digital de la biblioteca, introduciendo el concepto de Biblioteca-Red, derivado del estudio de la biblioteca desde la óptica organizacional y de los factores del entorno que la moldean. / 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
