SCIENCE CITATION INDEX, SCI

SCI is a citation index originally produced by the Institute for Scientific Information (ISI). It was officially
launched in 1964. It is now owned by Clarivate Analytics. Often the acronyms - SCI (Science citation Index),
ISI (Institute for Scientific Information) and WOS (Web of Science) are used Interchangeable.

Science Citation Index Expanded covers more than 8,500 notable and significant journals, across 150
disciplines, from 1900 to the present. These are alternatively described as the world’s leading journals of
science and technology, because of a rigorous selection process.

The index is made available online through different platforms, such as the Web of Science and SciSearch.
This database allows a researcher to identify which later articles have cited any particular earlier article,
or have cited the articles of any particular author, or have been cited most frequently.

A Wikipedia article on Web of Science describes it as a unifying research tool which enables the user
to acquire, analyze, and disseminate database information in a timely manner. This is accomplished
because of the creation of a common vocabulary, called ontology, for varied search terms and varied
data. Moreover, search terms generate related information across categories.

Acceptable content for Web of Science is determined by an evaluation and selection process based on the
following criteria: impact, influence, timeliness, peer review, and geographic representation.

The multidisciplinary aspect allows the researcher to easily search outside of his discipline and one
advantage of WOS over Scopus is the depth of coverage, with the full WOS database going back to 1945
and Scopus going back to 1966. However, Scopus and WOS complement each other as neither resource
is all inclusive.”
