Journal metrics attempt  to quantify the research impact of a publication.  Referred to as the impact factor, these calculations attempt to provide context for the scientific importance, or relevance of a journal article or journal title. There are different ways to measure journal impact.
Traditionally, two different companies have provided data on publishing trends:
	- Journal Citation Reports (JCR) (Clarivate - formerly produced by Thompson Scientific) 
- CiteScore (Elsevier / Scopus)
The library licenses the Scopus database from Elsevier.  We do not have a license to the JCR.  To learn more, see the library's guide on Journal Metrics. The library also has a guide to the Scopus database.
