| Kopsavilkums≠ | PubMed is a free, publicly accessible literature database maintained by the National Library of Medicine (NLM), a division of the U.S. National Institutes of Health. It provides access to biomedical and life sciences literature from MEDLINE (the curated subset of ~30 million indexed journal articles), life science journals, in-process articles, and preprints. MEDLINE, established in 1966, is the gold standard for biomedical literature indexing, using MeSH (Medical Subject Headings), a hierarchical controlled vocabulary of ~33,000 terms. PubMed is the primary discovery tool for clinicians, researchers, and healthcare professionals worldwide seeking evidence-based information. | 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. |
