Delhi Public Library is one of best public libraries of India. It is an autonomous organization under the Ministry of Tourism and Culture and governed by Delhi Library Board. It is fully financed by the Government of India. Actually it consists of a network of Zonal Libraries, Branches and Sub-branches, R.C.Libraries, Community Libraries, Deposit Stations, Sports Libraries, Mobile Library, Braille library, etc. spread all over Delhi. Its total collection is over 14 lakh books in Hindi, English, Urdu, Punjabi & other Indian Languages. Today, it added a new milestone in its journey. It made its Catalogue online.
