Indicators of Publication Research Impact: Journal Metrics

Metrics to help you demonstrate the scholarly impact of articles, authors, and journals

Journal Metrics

How significant are the journals in which you've been publishing your articles?

Impact Factor and Immediacy Index (Web of Science data)

College of Charleston subscribes to Journal Citation Reports (JCR) which provides long-established indicators of journal prestige, based upon the highly-selective set of journals indexed in Web of Science.

JCR metrics available include:

  • Journal Impact Factor – a measure of the frequency with which the "average article" in a particular journal has been cited during a two-year period
  • Five-year Journal Impact Factor – a measure of the frequency with which the "average article" in a journal has been cited during a five-year period
  • Immediacy Index – indicates how quickly articles in a journal tend to be cited by analyzing citation data for a single year
  • Journal rankings by each of the above metrics

The following brief videos provide an introduction to the platform and the metrics:

CiteScore and Source Normalized Impact per Paper (Scopus data)

CiteScore Metrics, a recent initiative of Elsevier publishing, are obtained from data within the Scopus database, which indexes a greater variety of journals than Web of Science. They also include a broader variety of material types.

CiteScore metrics include:

  • CiteScore – much like a three-year Journal Impact Factor (see CiteScore methodology)
  • Source Normalized Impact per Paper (SNIP) – measures contextual citation impact by weighting citations based on the total number of citations in a subject field, using Scopus data (see a description of SNIP)
  • Scimago Journal Rank (SJR) – a size-independent indicator of scientific journal prestige (see a description of SJR)
  • Journal rankings by each of the above metrics
