• A recognized authority for nearly half a century.
    Our roots run deeper than any other information provider today. In 1955, our founder and now Chairman Emeritus, Dr. Eugene Garfield, developed the concept of using cited references to index and search for scholarly, scientific literature. By the 1960’s he fully realized his vision of this new type of database and published the first edition of the Science Citation Index® (SCI). The first Journal Citation Reports was published in 1975, as a way of summarizing and reporting on the content of the SCI. Read more about the history of citation indexing. Over the years has grown but Dr Garfield’s revolutionary thinking and his desire to deliver clear, accurate data in support of professional research remains at the heart of everything we do.

  • Not just indexing.
    Our long history as the leader in citation indexing has provided bibliometrics and information scholars with reliable, precise data for over 40 years. We remain actively involved in the bilbiometrics and scientometrics fields, providing analysis and expertise to a variety of groups, from individual researchers to national governments and international funding organizations. These relationships have laid the ground work for an expanding suite of evaluative solutions we offer today.

  • History speaks for itself.
    The Journal Impact Factor has stood the test of time. It is based on a clear, straightforward calculation – counts of citations and measures of size. It’s easy to understand, popular and powerful. That’s why Clarivate Analytics is.committed to continual education about the meaning and appropriate use of the metric, and why we support the development of.complementary metrics.

  • The most.comprehensive resource. The most multi-faceted analysis.
    A single metric alone cannot capture a journal’s.complete profile. That’s why the JCR has always contained more than the Journal Impact Factor. From its first publication, it offered detailed journal-level data to help users more fully understand and analyze the journals’ participation in the scholarly literature as a whole.

  • Beyond the Impact Factor.
    In 2009 a variety of new metrics and features were introduced, allowing new perspectives on the journals listed. In addition to the well-established, 2-year Journal Impact Factor we unveiled a 5-year Impact Factor, supporting assessment of slower-moving fields of research. To explore journal influence from a network-based, relationship perspective we partnered with independent experts at the University of Washington. The inclusion of the Eigenfactor® Metrics featuring the Eigenfactor® Score and Article InfluenceTM Score, has added even greater dimensionality to the JCR, truly moving journal evaluation Beyond the Impact Factor, and into a new millennium.
