| Abstract | Program verification is a relatively new application area for symbolic mathematical systems. We report on an interactive program verification system, based on the inductive assertion method, which system is implemented using an existing symbolic mathematical language and supporting system, Reduce. Reduce has been augmented with a number of capabilities which are important to program verification, particularly transformations on relational and Boolean expressions. We believe these capabilities would be valuable in other contexts and should be incorporated more widely into symbolic mathematical systems for general use. The program verification application can serve as a guide to an appropriate definition of such capabilities, particularly with regard to the need to distinguish between undefined program variables and polynomial indeterminates. Additional capabilities which would benefit the program verification application include representation of user-defined functions by internal forms which directly incorporate properties such as commutativity and associativity (as is commonly done with plus and times), and a comprehensive facility for defining conditionally applicable transformations. |

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.
