Data curation is the active and ongoing management of data through its lifecycle of interest and usefulness to scholarship, science, and education. Data curation practices include appraisal and selection, representation and organization of data for access and use over time. Librarians can assist researchers with data curation by maintaining and adding value to research data for current and future use; specifically, working directly with researchers to ensure the active management and appraisal of data over the lifecycle of scholarly and scientific materials. A librarian can take measures to ensure that data is documented, maintained, and available over time by assisting researchers to create and implement a data management plan. This plan also allows provisions for data to be preserved for future use.
