Computerization of the Edward Lee Greene Herbarium at Notre Dame is described. Reasons for the justification of such a project and the steps involved in data accumulation and data processing are presented. Results are or will be available in two forms: 1) formal publications containing summary information, including information on the more than 4400 taxa that Greene named; and 2) a computerized data bank that today can provide answers to questions from individual systematists about the 65,000 specimens. Problems in automation are discussed, as are the relation of this project to similar ones. Finally, an invitation is extended to readers to query the data bank without cost.
