|Abstract||The technological development of the past 25 years, such as the electronic database, online services, CD-ROMs and the introduction of internet has radically transformed the process and access to information through catalogues. AACR2 rules cover the description of and the provision of access points for all library materials. The rules for description are based on the general frame work for the description of library materials the general international standard bibliographical description (ISBD(G)). The transformation of ISBD(G) to AACR2 is one phase. The second phase leads to creation of machine readable metadata. The most popular are Dublin core, UNIMARC, MARC21. Another local library software LIBSYS which is used in Indian libraries has also been used here for presentation of the mapping between different formats to draw conclusions to make them interoperable. As far as metadata interoperability is concerned, the OPAC display, now almost completely dependant on the AACR2 the world over requires minimum data aggregation, mainly the author, title, series, subject, etc. aggregation which are the mandatory fields prescribed by IFLA.|

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 9 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.
