Elsevier Announces Enhanced Journal Metrics SNIP and SJR Now Available in Scopus® PR Newswire AMSTERDAM, November 22, 2012 AMSTERDAM, November 22, 2012 /PRNewswire/ -- Providing researchers with a more effective journal evaluation Elsevier, a world-leading provider of scientific, technical and medical information products and services, announces publication of enhanced journal metrics SNIP (Normalized Impact per Paper) and the SJR (SCImago Journal Rank) which are now available in Scopus, the world's largest scholarly abstract and citation database. Modifications to SNIP, developed by Leiden University's Centre for Science & Technology Studies (CWTS), include improved benchmarking capabilities across different subject areas by correcting for differences in citation practices between fields. The new SNIP calculation results in an average score for all journals in Scopus to approximately equal one, simplifying the comparison of journal scores. The SJR, developed by the SCImago Research Group, has been enhanced with a refined algorithm to recognize the value of citations from closely related journals which compensates for an ever increasing volume of journals, at the same time also simplifying comparison amongst subject fields by an average value equal to one. Publishing in high impact journals has direct effects on a researcher's career; consequently journal evaluation is widely used by researchers to assess their publication options.
