I recommend to read the reply by Rob Keller in https://www.researchgate.net/post/Difference-and-importance-of-International-Scientific-Indexing-ISI-Scientific-Indexing-Services-SIS-and-Global-Impact-Factor-GIF.

Hi,

Journals indexed in ISI , that is called today Clarivate Analytics, are more reliable than in other databases because they are subject to acceptance conditions that they must follow. If you compare the recoded citations on ISI to other databases you can see that there are always less citations mentioned, because this database is very selective, and includes only refereed journals.

Dear Muhammad Amjad

Yes, they have capitalized on the well-known 'ISI' - Institute for Scientific Information - brand to market their service. This site appears to be an indexing service for which you must pay a price in order for your journal to be indexed in their database.

Dear Muhammad Amjad ,

Although the reply of Wolfgang R. Dick indicates the problem with the mentioned ISI (International Scientific Indexing), I will repeat more or less the reply I gave before. One needs to be very careful in this matter. It is indeed quite common to talk about ISI indexed journals. However when one talks about this be aware that:

International Scientific Indexing (ISI) is a bogus impact factor:

https://isindexing.com/isi/index.php (is a notorious example of a misleading metric https://beallslist.net/misleading-metrics/).

It is misleadingly referring to the Institute for Scientific Information (ISI) that use to provide indexing of major international journals and often referred to as ISI impact factor. It is nowadays the well-known Science Citation Index (SCIE) that is provided by Clarivate. To make things even more complicated…Clarivate reinstated the name ISI “ISI is the ‘university’ of Web of Science Group at Clarivate Analytics”. So the impact factor linked to Web of Science was originally produced by the Institute for Scientific Information (ISI) and used to be the Intellectual Property and Science business of Thomson Reuters (currently maintained by Clarivate Analytics).

The same is true for Scientific Indexing Services (SIS) and Global Impact Factor (GIF) both fake and virtually meaningless metrics. By the way another notorious one is Citefactor, that refers to the well-established CiteScore as developed by Scopus. All are mentioned as fake metrics: https://beallslist.net/misleading-metrics/

For more info about the only genuine impact factor (IF) or journal impact factor (JIF): https://en.wikipedia.org/wiki/Impact_factor

The journals that are really indexed in WoS database/indexing can be found here https://mjl.clarivate.com/home (either in ESCI or SCIE/SSCI) or in the enclosed file, all property of Clarivate (the successor of Thomson Reuters).

Best regards.

No such source can map 100% of publications worth mapping. They may also have country, continent or language biases. But without them, what else we have? It is better to have moonlight rather than wading through pitch dark.
