In thinking about how best to support the changes in scholarly and scientific work and also to accelerate these changes as a way of advancing scientific progress, science funding agencies began speaking about the need to systematically invest in what they called "cyberinfrastructure." This included not just information technologies but additionally the human and organizational resources needed to facilitate services and activities such as the training and retraining of scholars, the management and operation of the technical facilities that make up the IT environment and the scholarly tools that have been integrated with it, and the performance of data curation and preservation. This article describes how campus cyberinfrastructure challenge differs from the national cyberinfrastructure challenge. It then discusses the following cyberinfrastructure components from the campus perspective: (1) computational resources and data storage; (2) data management and curation; and (3) collaboration environments and virtual organizations. It ends by discussing the organizational and support implications of cyberinfrastructure. (Contains 12 notes.)
