Web of Science Core Collection |
Web of Science platform |
|
Summary |
A rich collection of citation indexes representing the citation connections between scholarly research articles found in the most globally significant journals, books, and proceedings in the sciences, social sciences, and art & humanities. The Web of Science Core Collection serves as the standard data set underpinning the journal impact metrics found in the Journal Citation Reports and the institutional performance metrics found in InCites. |
A platform providing access to multidisciplinary and regional citation indexes; specialist subject indexes; a patent family index; an index to scientific data sets; and a preprint index. The Web of Science provides a common search language, navigation environment, and data structure allowing researchers to search broadly across disparate resources and use the citation connections inherent to the index to navigate to relevant research results and measure impact. |
|
Number of journals |
> 22,171 journals + books and conference proceedings |
> 34,651 journals + books, proceedings, patents, and data sets |
|
Journal acceptance rate |
10-12% for the three core indices - Science Citation Index Expanded, Social Science Citation Index, and Arts & Humanities Citation Index - rates for the Emerging Sources Citation Index are generally higher. Each journal is rigorously evaluated prior to selection. Once selected, all content is indexed cover to cover. |
