Currently the knowledge base consists of 3000 abstracted, indexed and cross-referenced sites drawn from more than 250 institutions worldwide. This base is intentionally kept small. The listing provides a partial record of institutions whose materials are entered in the knowledge base. Over 250 institutions are covered, and the current knowledge base consists of over 2500 abstracted documents selected from these sites and/or submitted to GSSD. Each abstract also provides the direct link to the original document (or site).
Individual items in the knowledge base are cross-referenced and cross-indexed to facilitate understanding the linkages among issues and problems, as well as strategies and solutions – and enhance integration of alternative views of and perspectives on sustainability.
