New Scopus metric: CiteScore

December 2016 saw the launch of a new Scopus metric, CiteScore, along with associated other metrics. The new journal-level metrics will provide an additional view of journal performance and have been published for over 22,000 journals index in Scopus. This post will give you an overview of the metric and what it could mean for your journal.

What is it?

CiteScore is calculated from all citations recorded in Scopus in one year to content published in the last three years, divided by the number of items published. Unlike pre-existing metrics, such as SNIP and SJR, the CiteScore has been produced directly by Scopus and is easily replicable via the Scopus database. In addition to CiteScore Scopus are also publishing additional rankings, such as the CiteScore percentile based on subject categories and a monthly CiteScore tracker. The already established SNIP (Source Normalized Impact per Paper) and SJR (SCImago Journal Rank) will continue to be published.

There are three key differences to the Journal Impact Factor:

  1. It is based on the Scopus database rather than Web of Science, therefore the number of citations in certain subject areas will be notably higher.
  2. It takes into account a three-year citation window rather than two.
  3. The dominator includes all content published in the journal, not just articles and reviews.

How can I find my CiteScore?

All the Scopus metrics can be freely accessed at This includes the CiteScore, SNIP and SJR along with the percentile rankings and CiteScore Tracker.

What does it mean for my journal?

  • For journals that are indexed in Scopus, CiteScore will provide a simple metric that is easily recreated within the Scopus system.
  • For all Scopus indexed journals, the CiteScore will provide an additional way to benchmark citations against a much wider set of journals.
  • For journals that already have Impact Factors these advantages will be most notable in the Arts & Humanities where Clarivate Analytics does not publish Journal Impact Factors and the wider Social Sciences where the broader coverage in Scopus will have a larger effect.
  • Due to the nature of the calculation, journals that publish a large amount of front matter (editorials, peer commentaries, etc.) will perform worse by CiteScore than by Journal Impact Factor.

Things to consider

  • Citation counts have a large variance between subject areas, therefore we would always strongly encourage you to evaluate your journal’s performance using its subject quartile or percentile. (Thus you will be comparing journals with similar subject citation profiles.)
  • If you think your journal is not listed in the most appropriate subject areas, please contact your T&F Managing Editor.

The Taylor & Francis view

As your publishing partner, we want to ensure editors have the best tools to evaluate and understand the performance of their journals. We welcome additional quality journal metrics such as CiteScore, provided they are used appropriately. Therefore, editors are welcome to promote CiteScore on instructions for authors, submission pages and on Taylor & Francis Online, should your author community be interested in the metric.

If you would like to add this metric, please contact your T&F Managing Editor who will help organise this for you.
