The achievement of efficient, seamless access to electronic journal collections is a growing concern for libraries. Across the board, libraries are looking for a management solution. A number of non-commercial, albeit partial solutions are in development. Commercially, TDNet is presently the only solution offering integrated access to all TOCs, abstracts and full-text available from electronic and print only titles in a library's collection. TDNet uses a modular approach, enabling a range of search options; users can build sub-sets of the collection and define an e-mail alerting service. Other modules address administration and collection-management, as well as maintaining URLs and monitoring aggregations and bundles.
