The document discusses network based resource management in libraries. It describes how network based resource sharing allows libraries to provide more materials and services to users while reducing costs. The key benefits are improved access to resources, enabling institutions to make more efficient use of limited budgets, and avoiding unnecessary duplication. Some barriers include lack of infrastructure, copyright issues, and lack of cooperation between libraries. Conditions for successful network resource management include willingness to cooperate, effective communication systems, trained staff, and clear agreements between participants.
