概要	The Emerging Sources Citation Index (ESCI) is a supplement to Web of Science Core Collection launched by Clarivate Analytics in 2015 to expand journal coverage beyond the traditional Science Citation Index Expanded (SCI-E), Social Sciences Citation Index (SSCI), and Arts & Humanities Citation Index (A&HCI). ESCI includes high-quality, peer-reviewed journals that are newer, from underrepresented geographic regions, or from emerging disciplines not yet established in traditional indexes. Unlike SCI-E/SSCI journals, ESCI journals do not initially receive Impact Factor calculations. However, ESCI serves as a pathway: journals demonstrating sustained citation impact and adherence to quality standards may be promoted to SCI-E/SSCI and gain Impact Factor recognition. ESCI addresses systematic geographic and disciplinary biases in traditional indexing by including quality journals from developing economies, Eastern Europe, Latin America, and Asia.	Scopus, owned by Elsevier, is the world's largest abstract and citation database covering peer-reviewed journals, conference proceedings, and book chapters across all scientific disciplines. Launched in 2004, Scopus now indexes over 37 million documents from more than 6,500 journals, with expanded coverage of open-access publications and emerging regional journals. Scopus provides researchers and institutions with comprehensive citation tracking, field-normalized impact metrics (CiteScore, SJR, SNIP), and analytical tools for literature discovery, research evaluation, and institutional benchmarking.
