|Abstract||The universe of libraries has evolved and expanded from repository of books, journals and other non-print materials in physical format to knowledge repositories that contain collections in physical as well as electronic and multimedia format. With this changing environment of collection of library resources, the greatest challenge in front of libraries is to find out the best way to present, promote and make accessible the growing collections of heterogeneous resources. Libraries are required to look for search and discovering tools to provide seamless access to their resources. This article introduces basic philosophy of federated search and discovery tools. It elaborates on technological tools, techniques and protocols that are used for developing federated search and discovery tools. The article narrates disadvantages of federated search solutions and discovery tools as compared to conducting a search directly on the interface of primary database. The Concept of open URL as a technology used for link-resolving and finding “appropriate copy” is discussed briefly. Lastly, the article describes contemporary federated search solutions and discovery tools that are available commercially or as open source solution with their merits, demerits and comparative performance.|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDLI) project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and several other languages are available). It is designed to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is being developed to help students to prepare for entrance and competitive examinations, to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is being developed at Indian Institute of Technology Kharagpur.
NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
