Research Support: Journal Citation Reports (JCR)

This guide aims to help you start your research project, getting your research published and choose the best journal to publish your manuscript.

Journal Citation Reports

Journal Citation Report offers a systematic, objective means to critically evaluate the world's leading journals, with quantifiable, statistical information based on citation data.  By compiling articles cited references, JCR Web helps to measure research influence and impact at the journal and category levels, and shows the relationship between citing and cited journals. Available in Sciences and Social Sciences editions

Quartiles & JIF Percentiles

JIF Quartile:

A journal's quartile ranking is determined by comparing a journal to others in its JCR category based on Impact Factor score. If a journal falls in Q1, it means that the journal performs better than at least 75% of journals in that category, based on its Impact Factor score. 

JIF Percentile:

The journal’s rank in category, determined by Impact Factor, expressed as a percentile. For example, a journal with a JIF percentile of 89 performs better than 89% of journals in that category, based on its Impact Factor score. JIF percentiles give you a more granular view than quartiles do.

JIF Calculation

The Journal Impact Factor identifies the frequency with which an average article from a journal is cited in a particular year. You can use this number to evaluate or compare a journal’s relative importance to others in the same field or see how frequently articles are cited to determine which journals may be better for your collection.

 

Example 2017 Impact Factor Calculation:

Journal Impact Factor calculation

Impact Factor Numerator - Cites to recent items:

The numerator looks at citations in a particular JCR year to a journal's previous two years of content. For example, the 2017 Journal Impact Factor for a journal would take into account 2017 items that cited that journal's 2015 or 2016 content. The numerator includes citations to anything published by the journal in that 2015-2016 timeframe. 

Impact Factor Denominator - Number of recent items:

The denominator takes into account the number of citable items published in the journal in 2015 and 2016. Citable items include articles and reviews. Document types that aren't typically cited, e.g. letters or editorial materials, are not included in the Impact Factor denominator.
