The document defines a digital library as an online collection of digital objects that are managed and accessible according to international standards. A digital library applies new technologies to provide access to digital collections as an integral part of a traditional library's services. Key components of a digital library include its collection infrastructure, access infrastructure, computer/network infrastructure, digital resource organization, and trained manpower. Digital libraries offer advantages like 24/7 availability, cost reduction for governments, and information retrieval but also have limitations like lack of standardization and copyright/security issues.
