Data Updates
June 30, 2021
After the initial annual JCR release is published, this section will be updated biweekly with notes about pending additions or adjustments to the JCR data. All changes will be reflected in the JCR application when the dataset is reloaded and closed later in the year. These metrics can be considered official JCR data but are provisional until final publication in the reload.
Users may submit feedback for adjustments to citation and citable item counts. All feedback will be considered and fully investigated. Not all correction requests are eligible for the JCR Reload. Below are updates that are eligible.
JIF Denominator
-
Reclassifying document types for JIF denominator items related to citable vs non-citable counts
-
Adding missing items to the denominator count
-
Removing duplicated items from the denominator count
-
Count adjustment due to publication year correction
JIF Numerator
-
Unifying citations in the original JCR data set for a missing journal title variant, also known as a cited work variant
Unfortunately, numerator corrections that are currently out of scope for Reload are as follows:
-
Any citation not included in the original JCR data set
-
Citation where cited work is incorrectly attributed to a different journal in the JCR data
The deadline for submitting feedback for consideration for the reload is August 13, 2021.
Please note: Due to a production problem certain metrics and profile page functionality (including JIF Rank in Category, Quartile, and JIF Contributing items) are unavailable in the June release for the following journals:
-
Acta Pharmaceutica Sinica B,
-
Boletin de la Sociedad Geologica Mexicana,
-
Acta Agriculturae Scandinavica Section A-Animal Science
-
Journal of Addictive Diseases
These metrics will be fully updated for JCR October reload.
A technical problem on the journal profile page for Journal of Environmental Biology may cause the edition information and suppression notification box to display incorrectly in 2020 data. This correct edition for this journal is Emerging Sources Citation Index (ESCI) and the journal is not suppressed.

2019 Data Update
After JCR data were published in June 2020, we were able to obtain materials whose absence had prevented journals from receiving a Journal Impact Factor, as well as to correct metrics for a small number of journals. The 2019 JCR data (2020 release) are now complete and all updates have been fully incorporated into the product.
