properly attributed to William Bruce Cameron1, is often referred to when writing a foreword such as this: Journal level metrics continue to be an important part of the basket of metrics, complementing new and alternative metrics to provide a “Not everything that counts can be counted, and not multi-faceted view of a journal’s impact. On Scopus, you will find an everything that can be counted counts”. evolving and expanding suite of journal metrics that go beyond just journals to include most serial titles, including supplements, special This is undoubtedly true, but does not follow that nothing should be issues and conference proceedings. Freely available on Scopus you measured. There is much that can be counted that is important and will find CiteScore metrics, SCImago Journal Rank (SJR) and Source provides valuable perspectives on trends in academia, and there is an Normalized Impact per Paper (SNIP). increasing emphasis on this in the world of research today. The field of metrics relies on specialized academic study for its 1.2 Article-level metrics development and to capitalize on advances in technology; these PlumX Metrics is now the primary source of article-level metrics in scholarly outputs are increasingly being used by people
