Today’s seriously deteriorating global environmental conditions are focusing increased attention on the urgent need for effective public policy use of scientific information. Much scientific information which could inform public policy responses is published as grey literature but its use and influence is largely unknown. Using a case study of a UN-based intergovernmental advisory body that produces significant reports on the state of marine environments, this thesis establishes methodologies to improve understanding of the influence of scientific grey literature in print and digital formats. Whereas citation analysis, based on Web of Science data, has been used for several decades to measure the influence of scientific literature, this thesis demonstrated the limitations of relying solely on Web of Science data. Based on analysis of citation data drawn from Google, Google Scholar, monographs, as well as Web of Science, a more comprehensive metric of the use and influence of grey literature was developed.
