| Sažetak≠ | Ulrichsweb is a comprehensive, subscription-based global serials directory cataloging over 300,000 print and electronic journals, magazines, newspapers, and other periodical publications. Developed by ProQuest (originally R.R. Bowker), Ulrichsweb has served librarians and researchers for over 90 years as the authoritative source for journal metadata, publication information, and peer-review verification. A unique feature is Ulrichsweb's verification program: editorial staff contact journals directly to confirm peer-review claims, marking journals as 'refereed' only after validation. This verification process distinguishes legitimate peer-reviewed journals from predatory publishers falsely claiming peer review. | Journal Citation Reports (JCR) is an annual publication by Clarivate Analytics providing comprehensive citation metrics and performance analytics for journals indexed in Web of Science Core Collection. Launched in 1975, JCR publishes Impact Factor, the most widely recognized journal quality metric, alongside supplementary metrics (5-year IF, Journal Citation Indicator, Immediacy Index, Cited Half-Life, and citation distribution analysis). JCR is the authoritative source for journal ranking, benchmarking, and impact assessment in research evaluation systems globally. Access requires institutional subscription, though some institutions provide free access to affiliated researchers. |
