JCR allows evaluation and comparison of over 7,500 journals in science, technology, and the social sciences with respect to their importance in specific disciplines. The impact factor identifies the most highly cited journals in a discipline. For a description and discussion of the ISI Impact Factor and how it is calculated see Science Essays from Thomson Reuters.
Another possibility to locate journals in which to publish. Search by ISSN, journal, or publisher or browse by subject, country, or journal type. Journals are mostly science and technology, however some social science and arts and humanities titles are included.
