Checking a journal

Check in our tool first, then on the official site if needed.

Check a journal in secondsEnter a name or ISSN: HAC list, Scopus, quartile and DOAJ, with sources. The “Journal check” tool in the workspace. Open the tool

Check whether a journal is in Scopus

  2. 2Search for the journal by ISSN or title.
  3. 3Check the coverage years on the journal page: your paper's year must fall within them.

  4. 4Web of Science quartiles (JCR) require a paid subscription.

Spot a predatory journal

  5. 5Be careful if the fake databases above are listed as indexes.
