Web of Science, produced by ISI, provides web access to three citation databases, Science Citation Index Expanded, Social Sciences Citation Index, and the Arts and Humanities Citation Index, which can be searched individually or together. Coverage is from 1900-present; the databases are updated weekly.
Citation databases are bibliographic databases in which each article record includes the article's bibliography or reference list, allowing you to use citation information as an additional access point. Using the Cited Reference Search screen, you can search the database for articles that cite a known author or work. In addition, the General Search screen allows searching by subject keyword, author, journal title, author affiliation, and year. Cited Reference, Times Cited, and Related Records links within each article record allow you to retrieve related articles published both before and after an article of interest.
The Web of Science citation databases cover thousands of core journals across hundreds of disciplines:
