The Science Citation Index (SCI) is a comprehensive database that tracks citations of scientific articles across various disciplines. It helps researchers find relevant literature by showing how often a particular study has been cited by others, indicating its impact and relevance in the scientific community. Established by Eugene Garfield in 1964, the SCI is part of the larger Web of Science platform. It covers thousands of journals, allowing users to explore connections between research papers and identify trends in scientific research over time. This tool is essential for academics, helping them stay informed about advancements in their fields.
