en.wikipedia.org/wiki/Annals_of_Mathematics

A public excerpt of the 2023 Journal Citation Reports listing shows the entry for ANNALS OF MATHEMATICS as MATHEMATICS|Q1|3/489, with a 2023 JIF of 5.7. That means the article's denominator (330 journals) is outdated or incorrect for the 2023 JCR data.

An independent university announcement about the 2023 JCR also states that the Mathematics category contained 489 journals that year. So while third and 5.7 match the JCR excerpt, third out of 330 journals does not; it should be third out of 489.
