| সারসংক্ষেপ≠ | The Directory of Open Access Journals (DOAJ) is a community-maintained, freely accessible directory of high-quality, peer-reviewed open-access journals and articles established in 2003. DOAJ indexes over 20,000 open-access journals across all disciplines (sciences, social sciences, humanities, arts) from diverse geographic regions. The directory serves researchers, librarians, and administrators as the authoritative curated list of legitimate open-access journals—differentiating quality open-access publications from predatory journals that lack genuine peer review. DOAJ quality seal, awarded to journals meeting stricter governance and transparency criteria, enables identification of the highest-caliber open-access publications. | 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. |
