It has been suggested that digital libraries are more like archives than libraries and that library science cannot provide a theoretical foundation for handling digital data. We assert, however, that library and information science (LIS) provides much of the theoretical framework needed for digital libraries, and for data curation, and is a major source of vital research findings and professional education. This is a natural outcome of the LIS focus on the purposeful collection and organization of information and provision of services to support users, and on the considerable scale of relevant research activities long underway. The need for LIS contributions to the field is evident in results from our current research on scholarly and scientific data, digital collections, and our experiences with the Data Curation Educational Program (DCEP) masters and continuing education activities.Funded in part by Institute of Museum and Library Servicespublished or submitted for publicatio
