DESCRIPTION
EZID: Easy dataset identification & management Joan Starr, Manager, Strategic and Project Planning and EZID Service Manager, California Digital Library Data and data curation are assuming a growing role today’s research library. New approaches are needed both to address the resulting challenges and take advantage of the emerging opportunities. Long-term identifiers represent one such tool. In this presentation, Joan Starr will introduce identifiers and an application designed to make them easy to create and manage: EZID. She will provide a closer look at two identifier types: DOIs and ARKs, and discuss what bringing an identifier service to your institution might mean.
