The ISI also published the annual Journal Citation Reports which list an impact factor for each of the journals that it tracked. Within the scientific community, journal impact factors continue to play a large but controversial role in determining the kudos attached to a scientist's published research record.
The impact factor was devised by Eugene Garfield, the founder of the Institute for Scientific Information (ISI) in Philadelphia. Impact factors began to be calculated yearly starting from 1975 for journals listed in the Journal Citation Reports (JCR).

While these journals still did not receive an impact factor until the next year, they did contribute citations to the calculation of other journals' impact factors. [4] [5] In July 2022, Clarivate announced that journals in the ESCI obtain an impact factor effective from JCR Year 2022 first released in June 2023. [6]
However, an analysis by Elsevier, who created the journal evaluation metric CiteScore, has identified 216 journals from 70 publishers to be in the top 10 percent of the most-cited journals in their subject category based on the CiteScore while they did not have an impact factor. [18] It appears that the impact factor does not provide ...

When science journals were evaluated with a PageRank-based algorithm, however, the Journal of Biological Chemistry ranked first. [7] Using the Eigenfactor metric, the Journal of Biological Chemistry ranked 5th among all ISI-indexed journals in 2010. [8] The impact factor of the journal in 2021 was 5.486. [9]
The Journal of Management Studies' ISI Journal Citation Reports 2022 Impact factor is 10.5, with a ranking of 15/155 in the category 'Business (Social Science)' and 16/227 in the category 'Management (Social Science)'. [3]
