The Web of Science is a combination of three databases: Science Citation Index Expanded, Social Sciences Citation Index, Arts & Humanities Citation Index and Conference Proceedings Citation Index (Science & Technical Edition). It indexes more than 12,000 peer-reviewed journals, providing complete bibliographic data and author abstracts. Every item of significance is listed: articles, reviews, letters, notes, corrections, and editorials. In addition to access by author, title, and institution, it is also possible to search by cited authors and to find articles sharing one or more cited reference. It is possible to search the three databases independently or in any combination. Live links to electronic journals with full text are included for some publishers. The Conference Proceedings Citation Index (Science & Technical edition) is a Web of Science database that provides access to published literature from conferences, symposia, seminars, colloquia, workshops, and conventions worldwide. This resource offers access to conference proceedings and their impact on global research, including cited reference searching to track emerging ideas and new research beyond what is covered in the journal literature.
