Impact Factor and bibliometric indicators


About this module

When choosing where to submit your research, it can be helpful to consider a journal’s performance, or ‘citation impact’.

There are various metrics scholars rely on. In this module, we highlight some of the key ones. We start with the Impact Factor, probably the best known of the indicators available. Launched in the 1960s, it calculates the average number of citations received per published article. We move on to explore the Eigenfactor, SJR (SCimago Journal Rank), and SNIP (Source Normalized Impact per Paper). We complete our metrics tour by examining an indicator designed with authors, rather than journals, in mind; the H-Index.  The content for this module was created by Elsevier’s Dr. Andrew Plume, who specializes in scientometrics (the scientific qualification and analysis of science).

You’ll come away with a good overview of the metrics available and why using them together creates a much clearer picture of a journal’s performance.

Dr. Andrew Plume specializes in scientometrics (the scientific qualification and analysis of science). Through accumulating a broad spectrum of data that ranges from specific primary sources such as authors and single articles to the broadest data resources generated from countries and entire subject domains, Dr. Plume studies information flows in scholarly literature by analyzing patterns of publications and citations. One of his particular interests is the emergence of alternative metrics for research evaluation. Dr.
