The need to develop new OPACs that meet the needs of users better is becoming well acknowledged. How libraries can transform their OPACs to modern web friendly formats is not yet clear. This paper describes the State Library of Tasmania's experience in developing a new OPAC by exporting bibliographic data to a software package outside the ILMS. Issues involved with the provision of a user-oriented, browsable, or facet-driven interface are described, the two most important ones for libraries being how to change cataloguing processes so as to deliver the required data and search functionality, and how to share evaluative and usage data about our resources.
