This paper analyses the position and use of digital library services and open access resources in the chosen Central Universities in Delhi. The digital libraries have now become important appendages of the academic institutions, helping in teaching, learning, and research by means of effective accessibility to electronic information sources. The report examines the accessibility of the digital infrastructure, institutional repositories, subscribed databases, and large open access platforms like NDLI, Shodhganga, DOAJ, SWAYAM, and e-PG Pathshala. It also explores the level of awareness of the users, accessibility trends, and issues that faculty members, research scholars, and postgraduate students encounter when they need digital materials. The results suggest that the central university libraries have a significant digital provision and exposure to the open knowledge resources, though the lack of awareness, some technical limitations, and disproportionate use patterns are still present. The paper has given significance to librarians in fostering digital literacy and suggested the reinforcement of training programmes and institutional repository building to facilitate effective use of digital and open access resources within the higher education setting.
