    Abstract
    Since publication in 1977 of the first version of UNIMARC, conceived as an international exchange format for countries using different forms of MARC, it has been widely adopted as a national format. In France the National Library (BNF) uses UNIMARC for its bibliographic records, though with some differences from the official IFLA version. This. together with promotion by central government, has led to adoption of UNIMARC by most libraries. A permanent committee manages the development of UNIMARC, introducing regular changes, updates and guidelines. The BNF, however, has recently introduced further modifications and is working on a UNIMARC version of the INTERMARC authority list, without consulting French libraries. The French Librarians Association is accordingsly promoting BNF collaboration with UNIMARC users on future developments

    Abstract
    Information research using keywords is largely ignored by readers but in medium sized libraries such as that of the City of Science and Industry (Paris), with a multimedia collection of some 200.000 documents, it is the most effective tool. The reader, however, needs guidance in using this technique, and in refining searches to reduce noise. Examples are given demonstrating how keyword searches can identify non-indexed material, documents in other languages, and collective authors
