Web of Science™ data is uniquely selective, based on an independent editorial process combined with over 50 years of essential, accurate and unique curation, resulting in our unparalleled data structure.  Every article from every journal has been indexed, creating a comprehensive and complete data network.

“A significant improvement over a competitor’s APIs that I had been using in the past year. … Web of Science APIs return all the metadata, including author names, affiliations, addresses, and funding sources, among others. … the quality results from the Web of Science help us not only save time, but also perform error-free geographic and social network research.”

-Rick Shang, PhD in Philosophy-Neuroscience-Psychology, Washington University in St. Louis

Web of Science APIs seamlessly integrate the world’s best publication and citation data, giving you flexibility and control of the highest-quality and normalized bibliometric indicators.  Power and enrich your institution’s analysis and assessment capabilities.
