Journal Metrics: A Short History
The Journal Impact Factor was the first metric created for scholarly journals. Eugene Garfield first conceived of the idea of an impact factor in 1955. It is used to determine the impact a particular journal has in a given field of research and also to determine in which journal an author might wish to publish. It is reported each year in Journal Citation Reports.
The Journal Impact Factor was the only metric available for many years. But once the Internet made gathering statistics easier, other metrics were created. The Eigenfactor was the next popular metric, followed by SJR and SNIP. Definitions and links for these are on this page.
Please remember that these metrics provide only part of the story about a journal's utility and reputation. Your librarian can assist you with these metrics and journal evaluation in general.
