Global Map of Science: A Comprehensive Overlay Analysis of Scientific Disciplines (2009)

This research presents the Global Map of Science (2009), detailing the interconnectedness of 18 factors across 222 subject categories, including Environmental Science, Biomedical Sciences, Physical Sciences, and Social Sciences. Co-authored by Ismael Rafols, Alan Porter, and Loet Leydesdorff, the work utilizes overlay science maps as a novel tool for research policy and library management. It elucidates the dynamics of scientific communication and emphasizes the diversity and coherence of research areas, offering insights into interdisciplinary collaborations and trends.
