Can the level and quality of information services be sustained over a long period of time? Can all these activities be performed in an environment-friendly manner? Chowdhury takes the approach of a research monograph based on literature review and meta-analysis of the issues and challenges associated with the various forms of sustainability of digital information systems and services. He proposes new models for study and research based on the critical analysis of developments in related areas. Illustrated with case studies and informed by the latest research, the chapters cover: - Economic sustainability of information - Environmental sustainability of information - Social sustainability of information - Sustainability of digital libraries and information services - Emerging issues and policies - Sustainability of information models - Research issues and challenges.
