摘要:Four years out, this paper revisits the theme of VALA2000 and looks at the extent to which integrated library management systems have been developed to operate as hybrid library systems by focussing on the National Library of Australia's requirements in this area. A range of commercial portal products now extend (and may eventually replace) the OPAC. However, there is still a gap in the market place for workflow systems supporting the routine digitisation of collection material. In addition, library system vendors are only just beginning to provide the level of support needed by libraries that wish to build innovative web-based services based on the catalogue.
