The indicator shows the influence of the publication in databases and the level of popularity among the corresponding indexing category. Journals are divided into 4 roughly equal groups depending on the bibliometric indicators:

• Q1 (first quartile) is the highest ranking; publication in such journals is considered a very significant achievement for scientists.
• Q2 (second quartile) - journals are not as highly ranked as Q1, but are nevertheless recognised as highly influential among researchers.
• Q3 (third quartile) - these are the most popular journals among academics, as they have sufficient ranking for most scientific purposes.
• Q4 (fourth quartile) – publication in such journals also has a positive effect on the image of the researcher. In most cases, these journals have only recently been included in the database.

Quartile indicators are calculated in all the largest databases, depending on the quality of the journal and the number of citations. The ranking is updated every year, after the regular revision of the metrics. The indicator is calculated for each subject category.

1.Use the "Sources" feature of Scopus. This takes the user to a page with all the base journals

2.After that, select the filters to search for the journal, for example, the subject area. It is also possible to limit the search by the minimum of citations, documents, source type, and quartile.

The Scopus quartile data is also available to view on the Scimago Journal & Country Rank.
