I made up this little graphic to summarize how I see the evidence about journal rankings. The number column just shows the rank in each of the following sources
- SSCI – Social Science Citation Index (the granddaddy of them all),
- Google Scholar
- SJR : Scientific Journal Rankings
- N/R not included in the ranking source
Also think about the FT 50 where one would say JAR TAR and JAE would be ranked 2 as they were all added the same year, AOS 4 as added three years later, CAR as 5 as added six years later and RAST as 6 being voted in via a ballot exercise immediately after CAR was added by consensus.
