The National Digital Library of India (NDLI) jointly with Central Library, IIT Kharagpur is organizing the 4th international symposium on "Knowledge Engineering in Digital Library Design (KEDLD-2025)". In today’s rapidly evolving digital information landscape, Knowledge Engineering, Artificial Intelligence (AI) and Machine Learning (ML) are pivotal to enhancing the scope, accessibility and performance of digital libraries. This symposium will:
National Digital Library of India (NDLI) is a comprehensive virtual repository of learning resources designed to serve a diverse learner community. Sponsored and mentored by the Ministry of Education, Government of India, under the National Mission on Education through Information and Communication Technology (NMEICT), NDLI is developed, operated and maintained by the Indian Institute of Technology, Kharagpur. As of April 2025, the platform offers 125 million digital resources and has 94 million registered users, demonstrating its nationwide reach. Its federated search architecture, built on open-source technologies, supports a high volume of concurrent queries, ensuring swift and reliable access even during peak demand.
NDLI delivers tailored services for school and college students, job aspirants, researchers and lifelong learners. It accommodates content in all languages and currently supports search in the 14 most widely used Indian languages, making it a truly multilingual and inclusive platform. Accessible via both web and mobile app, NDLI organizes content across dedicated domains- School Education, Higher Education, Research, Career Development, Cultural Archives, Judicial Resources, Newspaper Archives, and Patents & Standards. Beyond aggregation, NDLI develops high-quality learning modules for major national competitive examinations such as JEE, NEET and various government recruitment tests. The NDLI Club outreach initiative promotes activity-based learning in alignment with NEP 2020, helping students and educators make the most of the platform.
Established in 1951 as the first institute of the IIT system, IIT Kharagpur was founded to advance knowledge in areas of national and global significance.
With over 770 faculty members, more than 900 staff and a community of 15,000 students and researchers, the institute pursues broad-based education to equip learners with best-in-class professional capabilities.
The Central Library is the institute’s learning hub, offering a conducive environment across six air-conditioned reading halls that can seat over 2,000 users simultaneously. It operates from 8 AM to midnight on regular days and provides round-the-clock access for 15 days during semester examinations. The Library subscribes to more than 26,466 e-journals, over 257,726 e-books and 31 electronic databases as of March 31 2025. It also holds subscriptions to standards from ASME, SAE, ISO, BIS, IEC and ASTM, and provides access to all major publisher e-journals via the One Nation One Subscription (ONOS) Phase-I scheme. Various digital library services are continuously rendered to meet the needs of its user community.
The National Digital Library of India (NDLI) invites researchers, scholars, practitioners, and policymakers to submit papers for the international symposium “Knowledge Engineering for Digital Library Design.”
