The new SCImago Journal & Country Rank <http://www.scimagojr.com> system utilizes data from Elsevier's Scopus database to produce a variety of scholarly journal and country rankings. This portal makes rankings by subject areas (27) or subject categories (295) showing the visibility of journals and countries through scientific indicators like SJR, H-index, Total docs., Total refs., Total cites, Citable docs., Cites per docs., Self-citation, etc., since 1996 to 2006. You can select a threshold for this indicators. SJR is based in the “Page Rank” algorithm in order to weigh the citations by the journal cited.
These indicators have been calculated on March 2007 and will be updated periodically. For this reason some of the figures showed in the SJR portal and Scopus® may be not match.
