The quartile (Q) of a journal can be found by viewing its impact factor and number of citations on the journal's official website or in databases such as Web of Science or Scopus. Some researchers and scholars also compile their own journal rankings, which can help determine the quartile of a journal.

Each subject group of magazines is divided into four quartiles: Q1, Q2, Q3, Q4. Q1 is occupied by the top 25% of journals in the list; Q2 is occupied by journals in the 25 to 50% group; Q3 is occupied by journals in the 50 to 75% group and Q4 is occupied by journals in the 75 to 100% group.

You can search the name of the journal in the clarivate analytics master journal list search page to confirm whether the journal is SCI/SCIE indexed. Difference between SCI/SCIE? In terms of quality, both SCI and SCIE are the same. But some journals are open access and some are subscription based.

Web of Science is used to track, evaluate, and compare scientific research. Scientists have access to assessments of articles and journals, such as the number of citations, impact factor, and other metrics.
