SCImago
Non-Federal Website: SCImago makes use of data supplied by Scopus which covers 13,000 journals. Scopus has a systematic policy on content inclusion and adds all new BioMed Central titles to its database on an annual basis, and so SCImago contains reliable bibliometric data and rankings for around 100 BioMed Central journals. The SCImago Journal Rank (SJR) is used as an alternative to the impact factor, as the primary measure of a journal's citation impact. SCImago have taken the mathematical approach behind the PageRank algorithm that has been central to Google's success as an internet search engine, and have adapted it to journal metrics in order to create the SCImago Journal Rank. The PageRank-style approach weights citations from journals according to how highly cited the journal itself it, using an iterative approach. The SJR calculation looks at citations made in a three year period, of articles published in an earlier, but overlapping, three year period. This makes the SJR a stable indicator of trends.
