Research Services: SJR, SNIP & CiteScore

The Glucksman Library's guide to assist researchers with all aspects of the research process from finding information to maximising impact.

SCImago Journal Rank (SJR)

The SJR is freely available on the web at  and via Scopus and uses citation data from Scopus. The SJR gives higher weight to citations from high impact journals and is calculated over a 3 year period. The SJR normalises for differences in citation behaviour between subject fields.


CiteScore is a new journal metric available at and via Scopus. The metric is calculated similarly to the Journal Impact Factor except it is over a three year period instead of two years and all document types are included.

Scopus Compare Journals Tool

With the Scopus Compare Journals tool you can compare up to 10 journals by CiteScore, SJR, SNIP, citations, documents, percent not cited and percent reviews.



SNIP (source normalized impact per paper) is also available at and via Scopus and uses citation data from Scopus. This indicator measures the average citation impact of the publications of a journal. The SNIP corrects for differences in citation practices between scientific fields, which allows for more accurate between-field comparisons of citation impact.

Using Scopus to Find Relevant Journals

This tutorial will show you how to use Scopus to analyse search results to find relevant journals and then compare journals by SJR, SNIP and other metrics.
