Welcome to Journal Metrics from Elsevier

The academic community has long been demanding more transparency, choice and accuracy in journal assessment. Elsevier now provides three alternative, transparent and accurate views of the true citation impact a journal makes:

The three different impact metrics are all based on methodologies developed by external bibliometricians and use Scopus as the data source. Scopus is the largest citation database of peer-reviewed literature and features tools to track, analyze and visualize research output. Via this website, the three journal metrics are provided free of charge.

About SNIP

Source Normalized Impact per Paper measures contextual citation impact by weighting citations based on the total number of citations in a subject field. As a field-normalized metric SNIP offers researchers, authors, and librarians the ability to benchmark and compare journals from different subject areas. This is especially helpful to researchers publishing in multidisciplinary fields.

About SJR

SCImago Journal Rank is a prestige metric based on the idea that 'all citations are not created equal'. With SJR, the subject field, quality and reputation of the journal have a direct effect on the value of a citation. It is a size-independent indicator and it ranks journals by their 'average prestige per article' and can be used for journal comparisons in the scientific evaluation process.
