Journal Citation Reports is a comprehensive and unique resource that allows you to evaluate and compare journals using citation data drawn from over 7,500 scholarly and technical journals from more than 3,300 publishers in over 60 countries. It is the only source of citation data on journals. It can show you the most frequently cited journals in a field, highest impact journals in a field, and the largest journals in a field. Citation and article counts are important indicators of how frequently current researchers are using individual journals. By tabulating and aggregating citation and article counts, JCR offers a unique perspective for journal evaluation and comparison.
