This paper presents a research study of data usage, creation and sharing within different research communities at UNSW. The study identifies emerging data usage and management needs within the e-research life cycle of diverse research communities. Comparison is made with the outcomes of other studies that have examined e-researcher work practices in relation to their data. The paper examines the findings to understand what role researchers see libraries having, and discusses the development of a framework that libraries can use to support the curation and management of data and the development of tools and library support services that can be used across disciplines
