This article describes developments in the use of information technology in the biological discipline of taxonomy, using both a historical overview and a detailed case study of a particular information systems project. Taxonomy has experienced problems with both its scientific legitimacy and its utility to other biologists. IT has been introduced into the discipline m response to these perceived problems. The information systems project described here served as a means of managing the tensions between scientific legitimacy and utility. It is (...) argued that this project represents an example of the use of a technological development m an attempt to re-engineer a discipline. The development of the information system is analyzed as an attempt to develop a scientific instrument that will embody a particular model of the discipline. The concerns of taxonomy with status and legitimacy make it appropriate that this new technology should be introduced at the interface between the discipline and the rest of biology as a means of disseminating results, and thus come to represent the discipline and the plants described to outsiders, just as the system represents outsiders to taxonomists.
