Web of Science Core Collection is one of the largest and most authoritative scientific publication citation databases in the world, providing access to a variety of indices of scientific literature. The scientometric database includes specialized indices that cover a wide range of disciplines and provide scientists and researchers with the information they need to analyze trends, citations, and impact of scientific research. Today, let's talk about Web of Science's core citation indexes and the fields of science they cover.
Web of Science Core Collection indexes
Science Citation Index-Expanded (SCIE) — Expanded Scientific Citation Index
Science Citation Index-Expanded is the first and primary citation index for research in the natural and technical sciences. SCIE was created in 1964 and has been regularly updated since then. Today, the citation index includes more than 9.5 thousand influential journals, making it the most comprehensive source of scientific information in the natural sciences.
- Period of publication:from 1900 to the present day
- Coverage of scientific disciplines: over 182 subject categories that include natural, exact, and technical sciences. Some of the disciplines covered are biology, chemistry, physics, mathematics, medicine, biomedicine, environmental science, and applied sciences such as engineering and information technology.
Social Sciences Citation Index (SSCI) — Social Sciences Citation Index
SSCI is an index covering research in the social sciences. SSCI covers more than 3,000 journals, making it one of the largest indexes for analyzing social science research. The index helps researchers track the citations of scientific publications in the social and behavioral sciences, as well as analyze the interaction of social disciplines with other scientific fields.
- Publication period:from 1900 to the present day
- Coverage of scientific disciplines: SSCI includes more than 47 scientific disciplines in the social sciences. This is a wide range of fields covering economics, management, sociology, psychology, law, political science, history, education, and others.
Arts & Humanities Citation Index (AHCI) — Arts & Humanities Citation Index
Arts & Humanities Citation Index is a specialized index from the Web of Science Core Collection ecosystem that covers publications in the arts and humanities. AHCI indexes more than 1,800 journals publishing high quality papers in the humanities and cultural sciences. AHCI is one of the few indexes focused specifically on the humanities, allowing researchers in this field to have access to specialized metrics and analyses.
- Period of publication:from 1975 to present
- Coverage of Scientific Disciplines: AHCI covers more than 25 fields in the humanities and cultural studies, such as philosophy, linguistics, literature, art history, religious studies, history, and others. This broad coverage helps researchers find works on related topics and analyze the diversity of scholarly approaches in the humanities.
Emerging Sources Citation Index (ESCI) — Emerging Sources Citation Index
The Emerging Sources Citation Index is an index within the Web of Science Core Collection created to track publications from new and emerging journals that are not yet included in major indexes such as SCIE, SSCI, or AHCI. ESCI was launched in 2015 and covers scientific publications that meet high editorial standards but are just beginning to gain influence in the scientific community. The index helps scientists find new areas for research and monitor emerging trends.
- Publication period: 2015-present
- Coverage of scientific disciplines:ESCI includes publications in various fields of science, from natural and technical sciences to social sciences and humanities (more than 252 subject categories in total). This makes the index an important resource for scientists interested in interdisciplinary research and in exploring new areas of science.
Specialized Web of Science Core Collection indexes provide scientists with access to the most current and relevant information, contributing to the development of science and maintaining a high level of academic research. These indexes help track scientific trends, assess the impact of publications, and foster interdisciplinary collaboration, making them an indispensable tool for researchers around the world.
