The Life Cycle of Digital Reference Sources

Academic libraries increasingly complement print-based reference collections with digitally-based reference for financial and educational reasons. However, library collection policies have sometimes lagged behind the technology curve. Too often, reference collection management practices have reflected a responsive attitude rather than a responsible, strategic stance. Many costs are associated with this service, and intellectual and psychological considerations make these resources a complex set of issues. This article examines the life cycle of digital reference sources by focusing on subscription databases: assessment, selection, acquisition, Web presentation and maintenance, archiving and preservation, and de-selection. It offers factors to consider because academic librarians must make decisions about these increasingly dynamic collections.
