Abstract
The purpose of the library portal is to enable users to discover relevant information from multiple distributed information resources; to seamlessly, and directly as possible, access related content; and to effectively use the information. The library portal is not a single technology. Rather it is a combination of several systems, standards, and protocols that interoperate to create a unified experience for the user. This chapter describes the various technologies and the relationship among the technologies that combine to enable the user to move seamlessly through the processes related to discovery, access, and use of information. A framework that incorporates many aspects of the JISC Information Environment Architecture (Joint Information Systems 2002) and the IMS Digital Repositories Framework (McLean and Lynch 2003) provides a structure to facilitate the discussion of issues related to each of the many individual components while it depicts the interrelationship among the components.
