Short answer: Use Clarivate’s Master Journal List as the authoritative source for current Web of Science journal coverage. Search the exact journal title or ISSN and review the collection information shown in the official record.
Do not rely only on a journal website, an old PDF list, a screenshot, or a third-party badge. Coverage can change, and Clarivate states that the Master Journal List should be treated as the authoritative source for coverage.
Check the exact journal identity because similar titles can cause confusion. Match the ISSN or eISSN, publisher, and journal title.
If your university requires a specific collection such as SCIE, SSCI, AHCI, or ESCI, confirm the collection rather than merely confirming that the title appears somewhere in Web of Science.
