    Abstract
    With increasing moves towards an integrated Europe the need for multilingual access to information becomes more pressing. One aspect of this need which has largely been neglected is the provision of multilingual access to OPACs and this paper is concerned with exploring this problem area. The need for multilingual OPAC search capabilities and the difficulties associated with this are discussed. The problems of subject access in particular are highlighted. Research into subject searching in monolingual OPACs is reviewed and its relevance to multilingual OPACs is outlined. Given the limitations of current machine translation of natural language it is likely that the utilisation of controlled subject search facilities. Finally some possible directions for further research are considered

    Abstract
    Experimental evidence suggests that enhancing the subject content of OPAC records can improve retrieval performance. This is based on the use of natural language index terms derived from the table of contents and back-of-the-book index of documents. The research reported here investigates the alternative approach of translating these natural language terms into controlled vocabulary. Subject queries were collected by interview at the catalogue, and indexing of the queries demonstrated the impressive ability of PRECIS, and to a lesser extent LCSH, to represent users' information needs. DDC performed poorly in this respect. The assumption was made that an index language adequately specific to represent users' queries should be adequate to represent document contents. Searches were carried out on three test databases, and both natural language and PRECIS enhancement of MARC records increased the number of relevant documents found, with PRECIS showing the better performance. However, with weak stemming the advantage of PRECIS was lost. Consideration must also be given to the potential advantages of controlled vocabulary, over and above basic retrieval performance measures
