Clarivate Analytics today released the 2017 Journal Citation Reports (JCR), an annual update of the world’s most influential and comprehensive resource for information on highly cited, peer-reviewed publications and the source of Journal Impact Factor (JIF) scores.
The analysis comprises citation data, impact and influence metrics, and millions of cited and citing journal data points from the Web of Science, the industry’s leading citation index in the sciences, social sciences and arts and humanities.

Consider climate change: Despite the thousands of papers published on climate change, controversy still lingers. To help add clarity to what the research data is revealing, the JCR identifies the top five research fields in climate change as Environmental Sciences, Meteorology & Atmospheric Sciences, Geosciences-Multidisciplinary, Ecology and Geography-Physical.
Furthermore, based on the Average Journal Impact Factor Percentile in the JCR, the top 10 journals across these five fields are:
US Department of Health Education & Welfare Public Health Service
Environmental Sciences
98.284
8. Bulletin of the American Meteorological Society
American Meteorological Society
Meteorology & Atmospheric Sciences
98.235
9. Gondwana Research
Elsevier
Geosciences, Multidisciplinary
98.138
10. ISPRS Journal of Photogrammetry and Remote Sensing
Elsevier
Geography, Physical
98.102
*Average JIF Percentile allows for comparison of journals across different categories by providing a normalized score based on the rank of the journal.
The 2017 JCR release, which represents 2016 citation data for literature within the sciences and social sciences, features 11,459 journal listings in 236 disciplines with 81 countries represented. A total of 132 journals received their first JIF in this report; 66% of journals saw a year-over-year increase in their JIF and 33% saw a decrease. These high-impact journals are at the heart of the Web of Science, the most comprehensive network of citations of over 33,000 journals.

The Journal Impact Factor is the ratio of last year’s citations to articles published in that journal in the two previous years. To ensure the JIF remains transparent to the research community, later this year the Web of Science will provide direct links to the source documents comprising the JIF denominator. In addition, with next year’s JCR release, direct links will also extend to the JIF numerator.
As Clarivate Analytics continues to accelerate its investment in innovation, reinforced by the acquisition of Publons earlier this month, this release of the JCR also includes new enhancements such as Percent Citable Items and new filters making analysis of the JCR easier. Percent Citable Items shows the percentage of a journal’s content that is considered “citable” for the JIF calculation.
