This paper will discuss the progress of the LIDDAS Project in Australia, concentrating on its implementation at Macquarie University Library. LIDDAS stands for Local Interlending and Document Delivery Administration System, an Australian project aimed at automating the interlibrary loan process and delivering vastly improved services to library customers. The paper will track Macquarie's involvement in the project, focusing on the challenges and particularly the opportunities brought about by the project. The project has been a lengthy one and there is no doubt that our aims in implementing the software have evolved as changes in higher education have impacted on the type of services expected from academic libraries. The paper will consider some of these changes and discuss how they have caused us to re-think our strategies for implementing the software.
