Contributions and case studies from Germany and other European countries, as well as from Asia, Australia and the US, demonstrate different aspects of reducing the "ecological footprint" in libraries. As well as looking at everyday procedures, the social role and responsibility of libraries as leaders in environmental sustainability are considered as are achieving a positive image for the library and the role of sustainability in marketing. The book also includes examples of sustainability in libraries through short papers presenting interesting cases.

The publication will be of interest to librarians from public, business, special and university libraries, teachers and students of library and information science as well as anyone interested in ecological solutions such as architects, library users, library governing bodies, certification agencies and professional library associations.
