The Journal Citation Reports is a comprehensive resource for journal evaluation, allowing access to data that helps you evaluate and compare scholarly journals, using citation data drawn from over 8,400 scholarly and technical journals worldwide.
Coverage is both multidisciplinary and international.
JCR Web shows the relationship between citing and cited journals. The Science Edition contains data from roughly 5,000 journals in the areas of science and technology. Citation data are not meant to replace informed peer review. Additionally, careful attention should be paid to the many conditions that can influence citation rates, such as language, journal history and format, publication schedule, and subject specialty. The number of articles given for journals listed in the JCR include only original research and review articles.
