This is the second in a series of updates to provide information on the launch of the 2021 Journal Citation Reports release.

In a recent blog post we discussed refinements in this year’s forthcoming release of the Journal Citation Reports (JCR)™, describing the addition of new content and hinting at a new metric for measuring the citation impact of a journal’s recent publications.

I’m now pleased to fully introduce the Journal Citation Indicator. By normalizing for different fields of research and their widely varying rates of publication and citation, the Journal Citation Indicator provides a single journal-level metric that can be easily interpreted and compared across disciplines.

The Journal Citation Indicator will be calculated for all journals in the Web of Science Core Collection™ – including those that do not have a Journal Impact Factor (JIF)™ – and published in the 2021 JCR in June.
