Journal Impact Factor (JIF or IF), a ratio comparing the number of citations to articles from the journal to the number of items that potentially could be cited. Higher numbers are "better." Find them on journal home pages, or in JCR: Journal Citation Reports.
Use database citation search features to see if a paper is cited by other authors. Ideally, you can find articles which get cited in newer journal articles written by
You can also look at various metrics for assessing the impact of an article
Commonly used surrogates for journal quality include:
Only compare surrogate measures across journals covering the same discipline and sub-discipline. The 2019 JIF for Journal of the American Chemical Society (14.612) is much lower than the 2019 JIF for World Psychiatry (40.595), but JACS is clearly a much better chemistry journal! The median 2019 JIF for physical chemistry journals is slightly higher than the 2019 JIF for organic chemistry journals. but this does not mean physical chemistry journals are "better."
The Becker model supplements traditional bibliometrics. Researchers track the impact of their work on
Around the world, countries have experimented with different approaches for assessing the quality and impact of their researchers. Sometimes impact or quality measures are used to determine funding allocations.
