The Web of Science scientometrics database is one of the most popular and influential scientific platforms in the world. For researchers, publication in journals indexed in this database is an indicator of the professional competence and influence of their scientific work. In this article, we will look at what Web of Science is, what citation indexes it includes, and so on.

What is the Web of Science database?
Web of Science (WoS) is a multidisciplinary platform that began operating in 1997. WoS indexes materials dating back to 1864 and covers thousands of scientific publications. The database includes journals that have undergone rigorous selection and belong to various citation indexes and collections.
Web of Science content
- 34,000+ peer-reviewed journals in the Core Collection
- 120,000+ scientific books (via Book Citation Index)
- 1.4 billion citations
- Records from 1864 to the present day
- 8 main indexes
Although Web of Science is a database covering various fields of science, technical disciplines still predominate on the platform.

Structure of the Web of Science database
The database is based on the Web of Science Core Collection, which consists of separate indexes.

Web of Science Core Collection indices
- Science Citation Index Expanded (SCIE) – an expanded citation index that includes more than 9,000 journals in 182 subject disciplines.
- Social Sciences Citation Index (SSCI) – a citation index for the social sciences, containing more than 3,500 publications in 47 subject disciplines.
- Arts & Humanities Citation Index (AHCI) – a citation index for the arts and humanities, containing more than 1,800 publications in 25 subject disciplines.
- Emerging Sources Citation Index (ESCI) – a citation index for new sources, containing more than 9,000 publications in over 250 disciplines.
- Conference Proceedings Citation Index – Science (CPCI-S) – covers all areas of science and technology.
- Conference Proceedings Citation Index – Social Science & Humanities (CPCI-SSH) – covers social sciences and humanities.
- Book Citation Index – Science (BKCI-S) – covers scientific books and book chapters in the natural sciences and technical sciences.
- Book Citation Index – Social Sciences & Humanities (BKCI-SSH) – indexes books and book chapters in the social sciences and humanities.
The most important indexes are SCIE, SSCI and AHCI, with the first two determining the quartile and impact factor.

- Research Commons – contains data from open sources, which improves the search for materials that are not indexed on the WoS platform
Web of Science is a product of Clarivate, so the database is linked to all of the company's developments. Thanks to this, publication in WoS not only creates opportunities for international partnership, but also facilitates scientific research using the Clarivate network.
Web of Science tools
- Journal Citation Reports (JCR) – created for the analysis of scientific journals. With the help of the database, you can view journal metrics, in particular Impact Factor, quartile, etc., and compare publications with each other.
- Endnote – a bibliography programme that simplifies the search for scientific materials and their citation.
- Publons – an online platform for authors, reviewers and editors, allowing them to present their scientific achievements and create research CVs.
- Web of Science My Research Assistant – a mobile application with Web of Science functions.
- InCites – an analytical platform for evaluating the scientific activity of institutions, researchers, and countries based on WoS data.
Publishing research in the Web of Science database is an important step in the career of every scientist. It confirms the scientific significance and international recognition of their work.
At the same time, journals indexed in WoS have very strict requirements for articles and a thorough review process. Sometimes, researchers may fail to take into account the basic requirements for article formatting. This significantly complicates the publication process, and many scientists lose their chance for successful publication at the stage of preparing an article for submission to a scientific journal.
