SCImago Journal Rank (SJR) is a portal that includes the journals and country scientific indicators developed from the information contained in the Scopus database (Elsevier). It is also a prestige metric based on the idea that "all citations are not created equal." With SJR, the subject field, quality and reputation of the journal has a direct effect on the value of a citation. Using the Google Page Rank algorithm, it was developed by a research group from the Consejo Superior de Investigaciones Científicas (CSIC), University of Granada, Extremadura, Carlos III (Madrid) and Alcalá de Henares.
