Web of Science consists of seven databases containing information gathered from thousands of scholarly journals, books, book series, reports, and more.
The three 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 indexes 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 contains the structures and critical supporting data for novel organic compounds reported in leading international journals. Many records show the reaction flow from starting material to final product. Index Chemicus is a vital source of new information on biologically active compounds and natural products.
Current Chemical Reactions® (CCR® Expanded)
Current Chemical Reactions contains single- and multi-step new synthetic methods taken from leading journals and patents from 39 issuing authorities. The overall reaction flow is provided for each method, along with a detailed and accurate graphical representation of each reaction step.
The Current
Chemical Reactions database contains an additional 140,000 reactions from
the prestigious Institut National de la Propriété Industrielle (INPI),
dating back to the 1800's.
Proceedings Search
You can now search for records of conference proceedings in Web of Science. You must have a subscription to one or both Conference Proceedings citation indexes to search for and to view conference records.
Availability of Records in All Databases Search
New Information!
Records become available in the All Databases Search function generally within 24 hours after we load them in Web of Science. As a result, you may retrieve fewer records (and a smaller Times Cited count) in an All Databases search than in Web of Science during this delayed period. If you encounter this discrepancy, we suggest that you return later and run a new All Databases search.
