Abstract:
The International Nuclear Information System (INIS) is a computer-based information system working on the principle of maximum decentralisation and minimum centralisation. The participating Member States and
international organisations prepare the inputs on a decentralised basis and the inputs so received are centrally processed and made available as INIS Atomindex - an indexing and abstracting periodical in
the field of nuclear science and technology. As a by product, the magnetic tapes containing the entries in the
periodical are made available to the participants. The Library and Information Services of the Bhabha Atomic Research Centre, Bombay, is the national inputting centre for INIS and receives the IN IS output tapes. These are processed using a DEC-10 computer facility of the National Centre for Software De,relopment and Computing Techniques (NCSDCT). The computer processing) a basic computer program query formulation technique and Selective Dissemination of Information (SDI) service are explained. The INIS record format and the processing record format, which is a fixed length record format, are described. The computer programs, are written in COBOL.
