Recently, Library Connect worked with librarian Jenny Delasalle to create a set of quick reference cards on research impact metrics. Both a poster (11x17) sized version, which includes all the metrics on one page, and a larger format featuring 4 metrics cards per page, are available for download. Each card provides a quick summary of the metric — including how it’s calculated, what it measures and whether it applies to journals, authors or documents — and serves as a good jumping off point for further discussions around metrics. To add a bit more context regarding their specific relationship to Scopus, we will be looking at individual cards and providing the Scopus connection, starting with SCImago Journal Rank (SJR).
As stated in the card, SJR weights citations based on the source they come from.The subject field, quality and reputation of the journal have a direct effect on the value of a citation. SJR also normalizes for differences in citation behavior between subject fields.
