This page tells you how to find some common research metrics (measures of research impact). Other metrics are available: for more information, please visit the Library Open Access Team's SciVal guide.
Number of times articles in a journal have been cited, divided by number of articles in the journal in the last 2 years.
Using Journal Citation Reports (JCR) via Web of Science
h = number of papers by an author, each of which has been cited at least h times.
SNIP = Source Normalized Impact per Paper.
Alternatively in Scopus, do a topic or article search, and click on a journal title in the Source column of the article details – journal SNIP factor appears on right.
Non-traditional impact measures such as social media mentions.
