Determine who the most influential individuals, institutions, papers, and publications are.

Essential Science IndicatorsSM is now supported on the InCites platform, a single environment for research and bibliometric assessment and evaluation to better support your long-term vision and keep you informed of the latest trends with a multifaceted analytics view.

With all the resources they need in one place, ESI users can determine the influential individuals, institutions, papers, publications, and countries in their field of study — as well as emerging research areas that could impact their work.

This unique and comprehensive compilation of science performance statistics and science trends data is based on journal article publication counts and citation data from Thomson Reuters databases. It is an ideal analytical resource for policymakers, administrators, analysts and information specialists in government agencies, universities, corporations, private laboratories, publishing companies, and foundations, as well as members of the scientific press and recruiters.
