Journal-level indicators are designed to measure the impact, prestige, or influence of a given journal title. The citation ratios common to journal metrics are often used as a kind of shorthand that helps scholars decide where to submit an article for publication or to make decisions in libraries about what journal subscriptions to obtain, retain, or cancel.
There are a number of reasons why a journal-level indicator, such as JIF, Eigenfactor, SJR, SNIP, CiteScore, etc., is not appropriate for evaluating the work of an individual scholar:
This resource provides total cites, Journal Impact Factor, 5-Year Impact Factor, Immediacy Index, Number of Articles, Eigenfactor Score, and Article Influence Score. It is generally not advised to compare Impact Factors and Immediacy Index scores between journals of different subject categories, because differing citation and publication rates between disciplines are not normalized.
