| Abstract | The average age of the 607,380 bridges in the U.S. is 42 years old. All bridges are required to be inspected every two years, and the frequency of these inspections increases as they age. The current bi-annual cost to inspect all bridges is $2.7 billion and each bridge requires 1-3 days for on-site inspection, depending on the complexity of the bridge. The longer it takes to identify a deficiency; the more stress that is exerted on other components of the bridge, resulting in a domino effect creating more defects. According to the Federal Highway Administration's 2009 statistics, $70.9 billion is needed to address the current backlog of deficient bridges. Advances in technology provide an opportunity to reduce the cost by 23.7%-26.9%, and improve the quality of bridge inspections by migrating from a periodic manual bridge inspection paradigm (e.g. once every 2 years or less) to an event-based inspection (e.g. inspect only when needed). |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
