Digital Library of India (DLI) is a digital collection of freely accessible rare books collected from various libraries in India. DLI started in early 2000 with the vision to archive all the significant literary, artistic and scientific works of mankind and to preserve digitally and make them available freely for every one over Internet for education, study, appreciation and for future generations. As a first step in realizing this vision, it is proposed to create the Digital Library with a free-to-read, searchable collection of one million books, predominantly in Indian languages. The Project was initiated by the Office of the Principal Scientific Advisor to the Government of India and subsequently taken over by the Ministry of Communications and Information Technology (MCIT). The idea was also to create a test bed for researchers to improve scanning techniques, optical character recognition, intelligent indexing and in general to promote Indian Language Technology Research.

Currently there are 21 participating centres of DL activities in India and The Indian Institute of Science has been the coordinator for the Digital Library of India with the involvement of contents creation centres (mega and small scanning centres) across the country. All the scanning centres send the data (scanned images in Tagged Image File Format (TIFF) along with the metadata of a book) to the Indian Institute of Science. After checking for the quality errors there at, the Institute hosts these documents in Digital Library website Portable Docuemnt Format (PDF).

Digital Library of India has currently 550,585 books available with 191,657,791 pages (191.632 Million). There are 231,379 books comprising of 64,208,401 pages of Indian languages available on DLI website. It is important to know users access behavior and their feedback that can help us to improve the effectiveness of these online systems and identify areas for improvement, ranging from user interface, functionality, and usage of resources itself. The DLI website is accessed worldwide and gets valuable feedbacks from users. The Indian Institute of Science has also been responding to several queries that arise from the users periodically. We need your feedback to improve the service and website look and feel. We will appriciate you if you can send your feedback to us at feedback.dli@gmail.com

The next big challenge in this project would be related to full text indexing and searching of contents of a book. The major challenge in full text search is for Indian languages books because there is no suitable Optical Character Recognition (OCR) software available that gives high accuracy. So there significant work needed to be done for full text searching of Indian language books.
