A comprehensive, multidisciplinary database that indexes scholarly journals in the sciences, social sciences, and arts and humanities is great but what makes Web of Science unique is its citation indexing. Article records come with links to both the works cited by the paper in question and links to future works that cited the article in question. Hence, there is a "web of science" moving back and forward in time.
Web of Science is considered the most authoritative resource for citation tracking. Using cited reference searching, you can track the history of a research topic, identify trends in a field or find the top researchers in that subject area.
Search for records that have cited a published work, and discover how a known idea or innovation has been confirmed, applied, improved, extended, or corrected.
You can search broadly across subjects and use the citation connections to navigate to relevant research results and measure their impact.
Find out who’s citing your research and the impact your work is having on other researchers.
