Comment: This articles compares samples of data from Scopus with Dimensions. It found that the citation counts in Dimensions are in line with those obtained in Scopus. The slightly lower numbers in citations give indication that the coverage of Dimensions may not be much greater than that of Scopus. Although, this is not explicitly checked.

Abstract: Dimensions is a partly free scholarly database launched by Digital Science in January 2018. Dimensions includes journal articles and citation counts, making it a potential new source of impact data. This article explores the value of Dimensions from an impact assessment perspective with an examination of Food Science research 2008–2018 and a random sample of 10,000 Scopus articles from 2012. The results include high correlations between citation counts from Scopus and Dimensions (0.96 by narrow field in 2012) as well as similar average counts. Almost all Scopus articles with DOIs were found in Dimensions (97% in 2012). Thus, the scholarly database component of Dimensions seems to be a plausible alternative to Scopus and the Web of Science for general citation analyses and for citation data in support of some types of research evaluations.
