Introduction — Web of Science consists of seven databases containing information gathered from thousands of scholarly journals, books, book series, reports, conferences, and more.

The three Web of Science citation databases contain the references cited by the authors of the articles. You can use these references to do cited reference searching. This type of search allows you to find articles that cite a previously published work.

• Science Citation Index Expanded (SCI-Expanded)
• Social Sciences Citation Index (SSCI)
• Arts & Humanities Citation Index (A&HCI)

The two conference proceedings citation databases include the published literature of the most significant conferences, symposia, seminars, colloquia, workshops, and conventions in a wide range of disciplines. Use these databases to track emerging ideas and new research in specific fields.

• Conference Proceedings Citation Index - Science (CPCI-S)
• Conference Proceedings Citation Index - Social Sciences & Humanities (CPCI-SSH)

The two chemistry databases allow you to create structure drawings to find chemical compounds and reactions. You can also search these databases for compound and reaction data.

• Index Chemicus (IC)
• Current Chemical Reactions (CCR-Expanded)

Note that the conference proceedings and chemistry databases require a separate subscription in addition to your subscription to Web of Science.
