User Agents in the Interface to Digital Libraries

Digital libraries are promising to make an immense information universe available to users. Large volumes of multimedia data will flow through high speed communication networks to satisfy the requests placed by patrons in this virtual space where research will take place. However, availability does not automatically imply effortless access for every individual user or group of users. The volume, complexity and dynamism of the information managed by digital libraries pose significant problems in bridging the accessibility gap between users’ needs and available resources.
