Citations symbolize the association of scientific ideas. The references that research authors cite in their papers make explicit links between their current research and prior work in the scientific literature archive.
Thomson Reuters databases index these intellectual links by listing both cited and citing works. Like other indexes, this enables you to move back in time to previously published papers. But uniquely you can also look forward in time to determine who has subsequently cited an earlier piece of research.
ISI Web of Knowledge delivers cited reference data that are accurate, consistent and without redundancies. Over 100 years of cited references are presented in a correct, standardized format that is truly browseable and searchable. No other database offers this level of accuracy and detail on such a multidisciplinary scale.
Quality guaranteed
Thomson Reuters makes sure that the information researchers receive is accurate, reliable, and without redundancies. A series of computer algorithms and human editorial checks spots potential errors, standardizes the look of data and optimizes retrievablility.
Other available services may miss verified cited references, but not Thomson Reuters. Our Authority File ensures the capture of as many correct citations as possible, by identifying and unifying inaccurately cited references and presenting them in a correct, standardized reference format.
