Several metrics are used to assess journal quality on the grounds of reputation and influence. Apart from the most commonly used Impact Factor, researchers often refer to SCImago Journal Rank or SJR to choose an appropriate journal in their field of research. Developed by SCImago using the Google PageRank™ algorithm, SJR retrieves information for various indicators from the Scopus database. It provides an ‘open access’ web-based environment to view the rank/performance of journals and countries in various scientific domains.
