  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.
