Examines various factors that contribute to an enabled environment for optimum utilisation of information resources. These include the digital form of information resources, which are inherently sharable, consortia as a concept to bring people and materials together and unified portals as technology to bring together disparate and heterogeneous resources for sharing and access. Explores the capabilities of emerging technologies that support sharing electronic resources in a heterogeneous and distributed consortia environment. The book also provides reviews of existing portal models for sharing resources and identifies the gap in meeting the objectives. The book provides a framework for a cost effective unified portal model to share the electronic information resources available in the participating libraries in a distributed digital environment.
