Q: How do I verify that my target journal is indexed in ISI, Scopus, or Scimago?
I wish to submit my article in a journal. While selecting my target journal, can I check the terms of the journal, that is, if the journal is indexed in Scopus, ISI or Scimago database?
I'm not sure what you mean by checking the "terms" of a journal. If I have understood your questions correctly, you wish to check if your target journal is indexed in an indexing database such as Scopus, ISI, or Scimago.
To check if your manuscript is indexed in the ISI Web of Science, you can log on to the following url http://mjl.clarivate.com/. Once you log in you can simply search by the full journal name or the ISSN number. The search result will show if your target journal is indexed in SCI, SCI-E, or ESCI. Please note that all SCI, SCI-E, or ESCI indexed journals are under the ISI web of science database.
To check if your target journal is indexed in Scimago please log on to https://www.scimagojr.com/journalsearch.php and search for your journal. This search engine is powered by Scopus and hence you should be verifying if your target journal is indexed in Scopus as well.
