Dr. S.S. Bhattacharya, Shri. B.D. Jayaram and Shri. N. H. Itagi , have jointly presented a paper titled "Documenting Indian Languages: The LIS India Experience", in the Prof. M. B. Emeneau Centenary International Conference Linguistics. Language Information Services (LIS), has been envisaged by them as a web based, multi media, comprehensive, authentic and an on going information source in the public domain on the Indian languages. It is envisaged to be useful for language planning and social development with a scope for social engineering.

           They accept that the century old Sir George Grierson's monumental Linguistic Survey of India remains the only nearly pan Indian survey giving descriptive account of the grammatical and other aspects of most of the Indian languages, with the surveys conducted in the post-Independence period being limited in scope. But they emphasize that Grierson's LSI, also was often found partial, inadequate and outdated in terms of coverage and content.

           Their project LIS starts with the list of 114 languages inclusive of the 102 speech forms with a total number of speakers of 10,000or more at the all-India level grouped under them as per the 1991 census. Currently research is on for 55 languages with reports of 27 languages received.

           LIS covers 12 broad aspects related to language research, and aims to promote the exploration of India as a linguistic, socio-linguistic, literary, cultural and a semantic area. Figures of language-family wise bilingualism and trilingualism are being worked out. The paper presents comprehensive statistical evidence to establish the nature of bilingualism and trilingualism in different regions of India .

          In conclusion, the paper presents the research findings of LIS project in contrast with Sir George Grierson's LSI data. There is an element of anticipation for better prospects from this survey.
