Σύνοψη	Web of Science (WoS) is the oldest and most established multidisciplinary citation database, maintained by Clarivate Analytics since 1964. It indexes over 21,000 peer-reviewed journals, conference proceedings, and books across sciences, social sciences, and humanities. WoS provides researchers, librarians, and administrators with comprehensive citation tracking, publication metrics, and research evaluation tools essential for literature review, impact assessment, and research strategy.	SCImago Journal Rank (SJR) is a prestige-weighted metric measuring journal citation impact based on Scopus data, developed by SCImago Group (a Spanish research consortium) in 2010. Unlike raw citation counts, SJR values citations from high-prestige journals more heavily than those from lower-prestige journals, similar to Google's PageRank algorithm. This prestige weighting approach accounts for field-specific citation cultures and provides fairer cross-discipline comparisons than raw impact factor. SJR is widely used for journal ranking, quality assessment, and publication targeting, complementing traditional Impact Factor with a prestige dimension.
