11.9.1 Digital Libraries Features and Functions

Also called electronic libraries and virtual libraries, digital libraries (DLs) employ high-performance, high-speed broadband network configurations for provisioning universal access to distributed multimedia information resources. Digital library (DL) implementation involves a clarification of procedures for developing and maintaining a secure, scalable, and extendible DL infrastructure that accommodates a diverse array of resources for enabling users to readily retrieve desired data. A DL requires a storage system that maintains vast amounts of information in diverse formats, advanced software for browsing and navigation, intelligent user interfaces, and multilingual services. DL implementations also establish Acceptable Use Policies (AUPs); guidelines for reference services, collection development, and intellectual property rights; and copyright procedures for material in digital formats. DLs support curricular enhancements in disciplines that include the earth sciences, mathematics, engineering, computer science, the arts, the humanities, microbiology, history, and high-energy physics.
