SCImago Journal Rank (SJR) is a journal metric built on Scopus citation data with a Google PageRank-like weighting. In a raw count every citation is one; in SJR a citation from a high-prestige source such as Nature contributes more than one from a low-impact venue. The aim is to dampen some effects of citation inflation and low-quality citation networks.
SJR is published on the Scimago Journal & Country Rank platform, often with its own quartile bands. Those Q values are not JCR quartiles. If a Turkish jury text does not say “SJR Q1,” substituting a Scimago Q for a JCR Q is risky. Still, SJR is a strong complement for discovery and international comparison—especially in Scopus-oriented settings.
Read SJR with CiteScore and SNIP: CiteScore is a flatter intensity measure, SNIP emphasizes field normalization, SJR emphasizes network prestige. All are journal-level. SJR alone does not guarantee peer-review quality. High-APC open-access venues with flashy SJR still need due diligence.
This site’s journal catalog aims to place Scimago/SJR beside JCR; Find quartile can show SJR Q in an ISSN lookup. Cross-read SJR with Scopus, quartile, and Impact Factor. Saying “high SJR” without a year is weak dossier language.
When you use SJR in a dossier or journal choice, state the year, official source, and category or collection name when relevant. Cross-reading related entries in this glossary prevents slogan-only explanations and produces verifiable wording that matches how committees and funders actually read evidence.
