2014 SNIP, SJR and IPP journal metrics now freely available online

on Wed, 06/17/2015 - 12:13

We’re pleased to announce that the 2014 journal metrics values are now freely available via The values will be visible in as of our next release which is scheduled for June 24, 2015.

It's impossible for one metric to serve all the necessary purposes – a mix of quantitative and qualitative evaluation is needed. When evaluating the performance of a journal, a variety of measures must be considered, of which citation analysis is only a part. An ideal “basket of metrics” contains measures that reflect the many ways a journal can demonstrate excellence, and, finally, individual assessment of the value of a journal’s contribution will require a mix of quantitative and qualitative evaluation.

All journals included in Scopus receive journal metric values and the extensive, global coverage of Scopus allows many journals that do not have an Impact Factor to view and understand their role in the scholarly publication landscape. All Scopus-based journal metric values are available for free at or via the public title list. If researchers must consider citation metrics, they should be able to see them. The data we offer today provides 2014 citation performance metrics for 22,639 serials in all subjects in science, social sciences and the arts and humanities. The free file contains over 34,000 current and historic serials titles, and an additional 18,238 one-time or multi-year proceedings.

Since 2010, we have offered two primary journal metrics – Source Normalized Impact per Paper (SNIP) and the SCImago Journal Rank (SJR). Since last year, we also include the IPP (Impact per Publication) in our offering of journal level citation metrics. IPP is a measure of the ratio of citations per paper published in the journal and is not normalized for the citation potential in its subject field. IPP is also the numerator in the calculation of SNIP.
