ANALYZING TRENDS IN SCIENTIFIC LITERATURE AND THE ENTERPRISE OF SCIENCE AS A WHOLE
This section of ScienceWatch.com contains articles drawing on Clarivate unique store of publication and citation statistics. Whether surveying a specific subject area and ranking its most-cited researchers and institutions, or assessing the output and impact of research in a given nation or region, or analyzing trends in the scientific literature and the enterprise of science as a whole—each article is grounded in Clarivate data.
In particular, citation analysis provides authority in reflecting the judgments that scientists themselves make in acknowledging the published research that they view as the most significant and useful.
