pgspaces.PDF Personal and group spaces: Integrating resources for users of digital libraries J. Alfredo Sánchez, Carlos Proal, Dámaris Pérez, Ana R. Carballo Library and Center for Research in Information and Automation Techno logies of the Universidad de las Américas-Puebla Abstract This paper presents an approach to integrate highly diverse resources available in digital libraries via personalizable interfaces and virtual collaboration areas. Digital libraries comprise vast digital repositories and a wide range of services, user environments and interfaces, all intended to support learning and collaborative research activities. We are developing a distributed digital library for which services and interfaces include, for example, mobile agents for federated information retrieval, recommendation agents, 3D visualization aids, and access to digital documents that support specific courses and projects. The diversity of these interfaces, plus the vo lume and dynamism of the digital library’s underlying collections, result in a complexity that has the potential to make the digital library unwieldy for the user. In order to assist users in dealing with this complexity, we have designed environments, termed personal and group spaces, which provide users with means to access and control all available resources in a uniform fashion from a single vantage point. We discuss our design and development experiences as well as initial usage results. Keywords: personalized interfaces, collaborative interfaces, digital libraries, personal spaces, group spaces, agents. 1. Introduction. The systems we have come to know as “digital libraries” are not really libraries in the usual sense. The abstractions of content and services that generally describe physical libraries have been used by researchers to convey some of the functionality enabled by digital libraries, but this metaphor does not even suggest the major differences that the introduction of a new medium en
