Journal Metrics - Key Sources

Journal metrics attempt to quantify the research impact of a publication or authors work. Referred to as the impact factor, these calculations attempt to provide context for the scientific importance, or relevance of a journal or publication.

Scopus (Sources/CiteScore (Elsevier)

The library licenses the Scopus database from Elsevier.

Scopus incorporates SCImago Journal & Country Rank along side their own proprietary metrics called CiteScor

(SJR) Scimago Journal and Country Rank
The SCImago Journal & Country Rank is a portal that includes the journals and country scientific indicators developed from the information contained in the Scopus® database (Elsevier B.V.). This platform takes its name from the SCImago Journal Rank (SJR) indicator, developed by SCImago from the widely known algorithm Google PageRank™.
(SNIP) CWTS Journal Indicators
"CWTS Journal Indicators provides free access to bibliometric indicators on scientific journals. The indicators have been calculated by Leiden University’s Centre for Science and Technology Studies (CWTS) based on the Scopus bibliographic database produced by Elsevier."

Eigenfactor Journal Ranking
"A journal's Eigenfactor score is our measure of the journal's total importance to the scientific community....The journal citation data for the Eigenfactor.org website come from the Thomson-Reuters Journal Citation Reports (JCR)." This metric is freely available online.

Google Scholar Metrics
“Google Scholar Metrics provide an easy way for authors to quickly gauge the visibility and influence of recent articles in scholarly publications"

Scopus CiteScore

Three different types of journal metrics are available:

CiteScore
SJR
SNIP

There are two approaches to access these scores:

Citescore (Sources). Citescore allows you to search and browse for individual titles to learn more about impact factors. Citescore is freely available online.
Journal Analyzer (Compare Sources). The Journal Analyzer allows you to compare multiple journals against each other in addition to seeing their individual impact factors. This tool is available to the DMU community through the library subscription to Scopus.

How are CiteScore metrics used in Scopus?
"CiteScore is a simple way of measuring the citation impact of sources, such as journals." This score is equivalent to the Journal Impact Factor provided by Clarivate Analytics.
How is SJR (SCImago Journal Rank) used in Scopus?
"SJR is weighted by the prestige of a journal. Subject field, quality, and reputation of the journal have a direct effect on the value of a citation."
How is SNIP (Source Normalized Impact per Paper) used in Scopus?
"SNIP measures a source’s contextual citation impact by weighting citations based on the total number of citations in a subject field. It helps you make a direct comparison of sources in different subject fields."
