CiteScore metrics updated with 2018 annual values

New functionality allows users to calculate CiteScore including user-set document types

CiteScore 2018 titles
Comprehensive coverage: Available for more than 23,830 titles on Scopus, CiteScore covers twice as many journals as the Impact Factor, including over 500 top-ranked titles.

The latest assessment of thousands of scholarly serial publications is now available for free on Scopus with the release of the 2018 CiteScore values.

This year more than 23,830 titles covering 330 disciplines were ranked across eight indicators that are all part of CiteScore metrics. These include: CiteScore, CiteScore Tracker, CiteScore Percentile, CiteScore Quartiles, CiteScore Rank, Citation Count, Document Count, and Percentage Cited. Calculating values for all titles included in Scopus, CiteScore covers 12,000+ more titles than the Impact Factor.

A rising tide: Almost 3 in 4 journals increased their CiteScore this year, with 1,450 more than doubling their 2017 values.

Access to CiteScore metrics’ underlying data is free for everyone, including non-Scopus subscribers, so values can be recalculated, offering transparency to researchers, publishers and the wider academic community.

Starting this year, calculations can be broken down by document type, enabling user-defined alternative CiteScore calculations that include only certain document types. Alongside the inclusion of all document types in the default CiteScore calculation, users can see the effect of manually restricting the calculation to any of three different sets of document types in both the numerator, i.e., citations counted, and denominator, i.e., publications counted.

This new functionality was based on user feedback, said Dr. Andrew Plume, Senior Director of Research Evaluation at Elsevier. “It provides additional transparency relating to the way certain document types might impact a title’s CiteScore value.”

Andrew Plume, PhDDr. Andrew Plume is Senior Director of Research Evaluation at Elsevier. He holds a PhD in plant molecular biology from the University of Queensland (Australia) and conducted postdoctoral research at Imperial College London. Since 2004, he has specialized in the application of scientometric approaches to understanding the dynamics of the world of research, from researchers and articles to system-wide studies.

CiteScore metrics are part of a collection of research metrics available on or through Scopus. Other metrics include journal, author, institutional, and article-level metrics captured in PlumX Metrics (covering Usage, Captures, Mentions, Social media and Citations), supporting a holistic view of research performance.

As Dr. Plume explained:

By making available a suite of citation and non-citation-based metrics, we underscore the two golden rules of research evaluation: always use both quantitative and qualitative indicators side-by-side, and when choosing quantitative indicators, always use more than one. With this approach, Elsevier is responsive to the needs of researchers and research leaders and is constantly scanning the horizon for useful new metrics to add to the array.

With CiteScore Tracker, journal performance can be monitored throughout the year alongside the release of the annual score.

CiteScore methodology

CiteScore is the number of citations received by a journal in one year to documents published in the three previous years, divided by the number of documents indexed in Scopus published in those same three years. <a href="" target="_blank">More information</a>

CiteScore metrics, including access to the underlying data, are free to access without a Scopus subscription in the following ways:

  • Scopus: Search and filter features let you explore the full range of CiteScore metrics for a group of journals (such as open access journals), a subject category or a publisher view. You can also access individual source profile pages and download the complete set of CiteScore metrics as a Microsoft Excel file.
  • Journal Insight pages on Access CiteScore metrics and other journal metrics in categories Impact, Speed and Reach for more than 2,500 journals published by Elsevier.
