Clarivate says the key highlights for 2021 include:
- More than 20,000 journals from 113 countries across five continents and 254 research categories in the sciences, social sciences, arts and humanities;
- More than 14,000 journals have at least one gold open access publication, with more than 4,600 being fully open access;
- New expanded content: Some 8,771 journals have been added to the JCR this year with the expansion of content across the full Web of Science Core Collection. The Arts & Humanities Citation Index (AHCI) and the Emerging Sources Citation Index (ESCI) will be included in the JCR for the first time this year, accounting for more than 70 per cent more content.
- New Journal Citation Indicator: Developed by the Institute for Scientific Information (ISI) at Clarivate, this new metric represents the average category-normalised citation impact for papers published in the prior three-year period, providing 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).
- New user experience: The 2021 JCR offers a revamped user interface by which the layered, rich data of the JCR can be easily and intuitively explored and visualised. Graphics improve the user experience with simpler, more direct searching while affording a deeper look into the data, says Clarivate. The new interface is based on extensive user feedback and dual access to the new and old platforms will be available through the end of 2021.
- Early Access content: The expanded coverage in this year’s release will introduce Early Access articles, reflecting the earliest availability of new research as it appears in the ‘version of record’ prior to official publication.
Dear Muhammad Hamzah Saleem ,
Interesting topic with a good summary of the new features in the JCReport of Clarivate released on June 30th 2021. For those wondering what this all means in ‘daily practice’ here some additional info:
-The Master Journal List of Clarivate (https://mjl.clarivate.com/home) will provide info on whether a journal is indexed in ESCI, SCIE or SSCI. Only journals indexed in SCIE/SSCI have an impact factor (see enclosed file Journal-IF)
-Clarivate provide a so-called Q rating as well (in order to see how well a journal performs in a particular discipline). For this you need the JCReport (see enclosed file JCReport)
-The info about the new metric JCI starts at page 493 in the JCReport (see enclosed file JCReport). Apparently Clarivate started with ESCI journals
There is already quite some discussion about the increase of the IF for most journals and what this means, see for example: https://www.researchgate.net/post/Unprecedented_growth_of_impact_factor
https://www.researchgate.net/post/Progressive_Inflation_Impact_Factor
There are a number of reasons for the increase of the IF (of the majority but certainly not all) journals:
-Clarivate Analytics has started to calculate the Journal Impact Factor (JIF) based on the date of electronic publication and not the date of print publication. See: https://scholarlykitchen.sspnet.org/2020/12/07/jif-calculation-2021/ It states, and I quote: “The next 2021 release (using 2020 data) will be a transition year, in which citations from Early Access records will be added the numerator of the JIF calculation but excluded from publication counts in the denominator.”
-The number of journals included in Clarivate’s JCR Report (and calculation of citations) increased significantly. See for example: https://www.researchgate.net/post/A_high_jump_of_the_number_of_mathematical_journals_with_JIF_2020where the number of journals in mathematics increased substantially,
-Last but not least, it might be that ‘we’ all published more over the past “COVID” period
Best regards.
PS. There is also quite some discussion about the limitations of the impact factor and the whole ‘fuzz’ about it:

Dear friends
I extracted the full list of the impact factor of mathematics journal based on new report released by Clarivate 2021. Please, click on the following link:

researchgate.net/publication/352934372_JCR_Impact_Factor_2021-_Full_list_of_journals_by_Clarivate_Analytics
I look forward to these analytics opening up in particular to free open access to support sharing of knowledge and data

Dear Matias Noll ,
Be careful. If you start searching on https://www.resurchify.com/if/impact-factor-search for an impact factor the following note appears: “Note: The impact score shown here is equivalent to the average number of times documents published in a journal/conference in the past two years have been cited in the current year (i.e., Cites / Doc. (2 years)). It is based on Scopus data and can be a little higher or different compared to the impact factor (IF) produced by Journal Citation Report. Please refer to the Web of Science data source to check the exact journal impact factor ™ (Thomson Reuters) metric.”
In other words, you will get an indication by using your link, but the real impact factor is given in Clarivate’s JCR Report (see my reply of July 4th for the latest list).
Best regards.
Publish, (be cited), or perish.
Thanks for sharing.
Best wishes.
