Statistics of journals with the greatest global impact.

Journal Citation Reports (JCR) is a database with statistics of the highest impact journals worldwide. It offers a systematic and objective means to evaluate the main research journals of the world. It also provides a unique perspective for the evaluation and comparison of journals, since it accumulates and tabulates the number of citations and articles of practically all the specialties of science, technology, and social sciences.

All metrics report on the activities of a journal within their scientific community. The metrics offered by JCR result from transparent calculations, are easy to understand, and can be repeated without difficulty.
