PNAS CiteScore

What is CiteScore?

CiteScore is a new standard that gives a more comprehensive, transparent and current view of a journal’s impact that will help you guide your journal more effectively in the future. CiteScore represents a robust approach for several reasons:
  • Observation Window. Research has found that in slower-moving fields, two years’ worth of data is too short; yet five years is too long to consider in faster-moving fields. Three years is the best compromise for a broad-scope database, such as Scopus, as it incorporates a representative proportion of citations across all disciplines while also reflecting relatively recent data.
  • Comprehensive. CiteScore is essentially the average citations per document that a title receives over a three-year period. This means not only articles and reviews but also letters, notes, editorials, conference papers and other documents are included. As a result, the numerator and the denominator used in the CiteScore calculation are consistent. This approach gives a more complete picture of citation impact and makes manipulating the calculation more difficult.
  • Transparent. The calculation of CiteScore is straightforward with no secret algorithms or hidden details. CiteScore metrics calculate the citations from all documents in year one to all documents published in the prior three years for a title. This offers a more robust and accurate indication of a journal’s impact.
