    Abstract
    Catalogue compilation and maintenance are time consuming. Developments from the mechanically produced guard catalogue to the OPAC have taken a course different from that which early pioineers might have predicted. Technical developments do not always match librarians' needs. The OPAC provides many retrieval possibilities, assists interlibrary cooperation and is available worldwide but cannot yet completely replace older catalogue forms. Only in the future will librarians realize whether online catalogues are the ideal system
