SJR: SCImago Journal & Country Rank

Unrestricted Access

Description

SJR: SCImago Journal & Country Rank is a free portal with journal rankings by subject and country. Its ranks journals according to the SCImago Journal Rank (SJR) indicator, which calculates journal influence by looking at both the number of citations received by a journal and the importance of the journal where the citation was published. It also offers other metrics, such as the H index, citations per document, references per document, and more. Journals can be analyzed by broad subject area, narrow subject category, or by country.

The journals and country data in SJR are drawn from the Scopus database. Citation data is drawn from over 34,000 titles from more than 5,000 international publishers. Country performance metrics cover over 230 countries worldwide. The project is maintained by SCImago, a research group at the Consejo Superior de Investigaciones Científicas (CSIC), University of Granada, Extremadura, Carlos III (Madrid) and Alcalá de Henares.
