Common questions

Common questions about CiteScore vs SJR (SCImago Journal Rank)

Are CiteScore and SJR both based on Scopus data?

+

Yes. Both draw their underlying citation data from Scopus, but are calculated by different organizations (Elsevier for CiteScore, the independent SCImago Research Group for SJR) using different methods.

Which one is field-normalized?

+

Neither corrects fully for cross-field citation-rate differences. SNIP, a third Scopus-based metric from Leiden University's CWTS, is built specifically for cross-field comparison.

Can a journal's CiteScore and SJR disagree?

+

Yes, often. Because SJR weights citations by the citing journal's prestige and CiteScore does not, the two can rank the same journal quite differently.

Do CiteScore and SJR replace the Journal Impact Factor?

+

No. All three are separate metrics computed from different underlying databases (CiteScore and SJR from Scopus, Impact Factor from Web of Science) using different windows and formulas. Many researchers and institutions consult more than one.
