- Journal-level metrics. Metrics have become a fact of life in many - if not all - fields of research and scholarship. In an age of information abundance (often termed ‘information overload’), having a shorthand for the signals for where in the ocean of published literature to focus our limited attention has become increasingly important.
- CiteScore metrics. CiteScore metrics are a suite of indicators calculated from data in Scopus, the world’s leading abstract and citation database of peer-reviewed literature.
- SCImago Journal Rank (SJR) SCImago Journal Rank (SJR) is based on the concept of a transfer of prestige between journals via their citation links. Drawing on a similar approach to the Google PageRank algorithm - which assumes that important websites are linked to from other important websites - SJR weights each incoming citation to a journal by the SJR of the citing journal, with a citation from a high-SJR source counting for more than a citation from a low-SJR source.
- Source Normalized Impact per Paper (SNIP) Source Normalized Impact per Paper (SNIP) is a sophisticated metric that intrinsically accounts for field-specific differences in citation practices.
Four Scopus-specific metrics can be found on a document’s metrics details page: total number of citations by a date range of the user’s choosing, citations per year for a range, citation benchmarking (percentile) and Field-weighted Citation Impact.
CiteScore metrics enrich the evaluation of serial titles and provide transparent data to help you measure the citation impact for journals, book series, conference proceedings and trade journals. This comprehensive, clear and current system of metrics for analysis can be accessed for free on Scopus.

Table 2 shows various metrics calculated from the data in Table 1, as well as the 2019 Impact Factor accessed via Journal Citation Reports. Comparing the CiteScore to the Impact factor (CS/IF) for the selected journals (column 3 of Table 2), the CiteScore is 1.69 ± 0.61 (mean and standard deviation) times that of the Impact Factor. A number greater...
Examining the ‘2019 cites per 2019 eligible articles’ from Table 2, it can clearly be seen that in every category there is a much higher citation rate for current-year articles in the top five journals compared to the middle five journals. Although always lower than the CiteScore, it is an indication that journals which publish papers that are more...
In 2019 the CiteScore changed the numerator in the calculation to cover citations over the entire period (2016–2019 in the data used here), previously only citations received in the reference year to articles published in the previous 3 years were counted. The effect of this can be seen in Table 2by comparing the CiteScore to the ‘CiteScore if only...
Comparing ‘CiteScore if using all documents’ to the CiteScore (which only uses eligible documents) (Table 2) indicates the reduction or increase in CiteScore if editorial type documents are included in the calculation rather than only eligible documents (e.g. similar to the previous CiteScore methodology compared to the new methodology). All of the...
