Abstract
Intelligent agents - software components designed to perform complex tasks for the user (with or without the presence of the user) - are used in a variety of settings, from instant messaging and Web auctions, to ATM network management and air traffic control systems. The technology also has applicability within libraries, adding a level of user-oriented control and flexibility to activities such as digital collection management and virtual reference. The use of intelligent agents to assist users with their searches has perhaps the greatest potential. This article provides background information on the use of agent technology in information settings, and reviews three library-based projects that utilize agent technology in a practical way.
