Journal Impact Factors are a proprietary measurement of journal quality based on the average number of citations to publications appearing in that journal over the last two publication years. i.e. the number of citations received in 2020 to 2018-2019 publications in a journal. Impact Factors are available for more than 20,000 journals across 254 defined fields and are published annually. Read more here.
This year’s release includes a 70% increase in included journal titles, expanding to include content from the Arts & Humanities Citation Index and the Emerging Sources Citation Index.
The Journal Citation Reports, is also launching a brand-new metric, the Journal Citation Indicator. The JCI is a field-normalized metric that can be used to compare journal rankings across disciplines and is available for all journals included in the Web of Science Core Collection- even those that do not have a Journal Impact Factor. A value of 1.0 represents the world average for the respective field. Read more here.
Impact Factors and the new Journal Citation Indicator are freely available to the Emory community through Emory University Library subscriptions.
