The SCImago Journal & Country Rank (SJR) is a publicly available portal that includes journals and scientific indicators from the information contained in the Scopus (Elsevier®) database (Bar-Ilan, 2008; Guerrero-Botea & Moya-Anegón, 2012). These indicators can be used to assess and analyze scientific domains. The journals may be compared or analyzed separately. Country rankings can also be compared or analyzed separately. The journals can be grouped by field (27 main subject areas), subject category (313 specific subject categories) or by country. Citation data is drawn from more than 34,100 titles from more than 5,000 international publishers, and performance metrics from 239 countries around the world. The SJCR also enables one to incorporate meaningful daily metrics into one’s web, as a clickable image widget.
