… Enriched ScienceDirect content in the fields of:
… Journals, Book Series, Handbooks, and eBooks
… 1995 to present
Using ScienceDirect with NextBio While viewing an article or book chapter on ScienceDirect, the keywords from that selected article or book chapter are matched against NextBio’s biomedical ontologies. Directly on the article page, researchers will find the NextBio application which presents key terms found in the selected article or book chapter.
Using ScienceDirect with NextBio The in-context pop-up allows the researcher to quickly gain an overview of the article from the perspective of their chosen term, and to quickly link through to other information.

New Perspective on Journal Metrics SCImago Journal Rank – SJR Source-Normalized Impact per Paper – SNIP INTRODUCING TWO JOURNAL METRICS
Metrics to Support User Needs http://www.info.scopus.com/News/content/latest
More on... SJR SJR is a prestige metric – citations weighted depending on where they come from - A journal transfers its prestige by citing - Prestige transferred = journal’s SJR e.g. Lancet SJR 2007 = 1.541 – high prestige e.g. Scandinavian Journal of Medicine and Science in Sports SJR 2007 = 0.153 – lower prestige A journal’s prestige is shared equally between its citations Normalize for differences in citation behaviour between subject fields Life Sciences journal
High impact, lots of citations
One citation = low value
Arts & Humanities journal
Low impact, few of citations
One citation = high value
More on... SNIP Calculate ‘Citation Potential’ for 2009 4. Citation Potential = average number of references to any 1-3 year old papers
SNIP = 2009 Impact / 2009 Citation Potential
Life Sciences – high impact, high Citation Potential
Arts & Humanities – low impact, low Citation Potential
Normalize for differences in citation behaviour between subject fields 1. Collect papers citing 1-3 year old papers in target journal in 2009 2. Collect reference lists of citing papers Etc . 3. Count number of references in citing papers to any (in any journal) 1-3 year old papers Etc.
