    Abstract
    State of the art review of enhancements in online catalogues over a 3 year period, taking for granted those features that are now standard and mainly discussing issues related to problem areas, in particular, subject access and user searching behaviour, as well as new developments that directly impinge on the catalogue's future: new interface developments and network access and resources

    Abstract
    Shortened and revised version of a paper presented during an Education Librarian's Group session at the Under One Umbrella Two Conference, organized by the Library Association in Manchester, 9-11 Jul 93. With the possibility of free text searching and easy access to CD-ROM databases, users often do not realise that subject searching is enhanced by familiarity with the controlled vocabulary underlying the indexing system of the database. Discusses the construction of information retrieval thesauri, the problems of terminology and how the use of thesauri can make searching more effective, using education thesauri as examples
