Web of Science (Arts & Humanities, Social Sciences, and Science Citation Indexes)

Web of Science indexes leading scholarly journals, books, proceedings, reports, and other formats. Its major subject areas include sciences, social sciences, and arts and humanities. The heart of the platform is the Web of Science Core Collection, which indexes over 20,000 scholarly journals and includes over 1 billion cited references. Indexing for each work in the Core Collection includes its authors, author affiliations, and cited references. In addition to the Core Collection, Web of Science provides access to several regional, subject, and format-specific databases.
