Who we are and how we got here:
A quick history of Web of Knowledge

Clarivate Web of Knowledge started with a single idea...and a man who could see the possibilities of that idea. In 1955, Dr. Eugene Garfield revolutionized scientific research with his concept of citation indexing and searching.

Decades later, technology finally caught up with his concept and Web of Science® brought Web linking and citation searching together to create a powerful and versatile research platform. Web of Knowledge was the next logical step — bringing together a full range of data, tools and technology in one, integrated, ever-evolving resource.
