Digital Library Issues Arising from Earth Science Data

چکیده
NASA, NOAA, and USGS collections of Earth science data are large, federated, and have active user communities and collections. Our experience raises five categories of issues for digital librarianship: Organization of the data in the collections is not well-described by text-based categorization principles Metadata organization for these data is not well-described by Dublin Core and needs attention to data access and data use patterns Digital librarianship requires risk management approaches to dealing with the unique threats to knowledge preservation specific to born-digital information Digital librarianship requires careful attention to archival cost management Professional reference librarians for these collections my require special training. This paper suggests three mechanisms for improving the quality of digital librarianship: Using a maturity model to assess the readiness of data for accession, for preservation, and for future data usefulness -Developing a risk management strategy for systematically dealing with threats of data loss Developing a life-cycle cost model for continuously evolving the collections and the data centers that house them.
