Where can one check free of charge the impact factors of all journals? jcr.clarivate.com seems to be one but it's not open to those with no subscription. Many other sources only show other metrics but not impact factors.

2Is it at all clear that there is such a place where you can check for free? Clarivate is putting a substantial effort into their product, they may simply not be interested to have it available for free.– Wolfgang BangerthCommented Oct 20, 2023 at 15:03

ok that makes sense, but just wonder if there's anything free out there to make things easier– feynmanCommented Oct 22, 2023 at 2:06

1Are you looking for journals for your future publications? Many journals publish their impact factor on their website. Isn't that enough?– SnijderfreyCommented Oct 22, 2023 at 17:14

yes and no, some new journals don't show impact factors yet some others that aren't SCI index don't have them either– feynmanCommented Oct 23, 2023 at 10:23

Several years ago, I used the following links to find impact factors for free:
https://becker.wustl.edu/resources/databases/isi-journal-citation-reports
https://admin-apps.webofknowledge.com/JCR/JCR
But now it seems these redirect to the one mentioned in the OP, and I can't access them in the Wayback machine. Similarly, the link below no longer works:
https://jcr.incites.thomsonreuters.com/JCRJournalHomeAction.action
It seems there's been some push to monetize impact factor. For mathematics, the following still works:
https://www.scijournal.org/math-journal-impact-factor-list.shtml
There are also alternatives to impact factor:
https://en.wikipedia.org/wiki/SCImago_Journal_Rank
https://www.scimagojr.com/journalrank.php
In practice, what I do nowadays is that, if the fourth link above doesn't list the impact factor for the journal I am considering, and if this is important for some reason, then I just google the name of the journal plus "impact factor" and usually find that the journal has listed it. But overall, I think it's appropriate to move away from "impact factor" as a way to measure anything at all, especially if JCR is trying to monetize it.
