National Digital Library of India (NDLI) is a virtual repository of learning resources. It is not just a repository with search/browse facilities but also provides a host of other services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, as part of its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching. This enables learners to find the right resource with least effort and in minimum time.
