Abstract: The goal of electronic content discovery with Metasearching is to investigate issues related to locating, retrieving, and promulgating information in large networked environments. The Internet and WWW provide a challenging environment for deployment of these services. The needs of information publishers - to maximize audience reach - and the user - to minimize information overload - require advanced technical solutions and investigative research. As the deep web of information grows at an exponential rate, efforts to make the technology more manageable and affordable are highly in demand. Applying advanced information retrieval techniques i.e. meta-search and open link resolver are some approach to such efforts. In this paper we present our attempt to apply open source initiatives for retrieval model based on NISO Standards, relevance mechanisms and a meta search technique as an integrated electronic resource discovery system for the Deep Web. This paper discusses challenges and issues involved in Meta-Searching, as well as practical issues such as retrieval effectiveness, usability and scalability.

Abstract: Metadata research drastically improved the resource discovery mechanism in accessing information from a large distributed environment. Even technological capabilities permit multiple metadata schemas for standardizing the structure and content of indexing information towards an efficient resource discovery. This paper presents the issues on standard metadata in order to pursue digital repositories and dynamic web pages. It proposes various means of harvesting metadata using optimum standards and protocols. It also enumerates inherent mechanisms for metadata harvesting in DSpace enabled repositories through various harvesting tools; and evaluates XML as current popular choice for metadata harvesting (OAI-PMH) and exchange. System support to multiple metadata formats in DSpace has been discussed thoroughly. Finally it recognizes interoperability and extensibility functions that are being realized increasingly towards a long-term management and preservation of digital objects. However the glimpses of metadata production tools (newer & developed) could accelerate the digital repository initiatives with an increasing popularity of open access movement in real world.

Abstract: The paper describes some recent projects and developments at the Library of the London School of Economics and Political Science (LSE). To support and assist learning and research the Library has introduced new resource discovery services, the Beta Catalogue and Cross Searcher federated search engine. There is close collaboration between the Library and LSE Centre for Learning Technology to provide online information skills training via Moodle. The LASSIE project has investigated the use of social software in libraries. LSE Library staffs are gradually introducing social software into their work. The LSE Institutional Repository, LSE Research Online, is managed by a team of Library staff. Two projects, VERSIONS and VIF, have explored the issue of uncertainty around different versions of an academic paper. The NEEO project has developed an open access repository for the research output of European economists. The digitisation of print collections is at an early stage.
