Journal Impact Factor via Journal Citation Reports is a metric intended to represent the research impact of an academic or scholarly journal through a ratio reflecting the yearly average number of citations to recent articles published in an academic journal. This is a unique metric offered through the InCites Journal Citation Reports database.
Eigenfactor (journal impact metric alternative) offers an alternative journal-level metric to the Journal Impact Factor. The intent of this metric is to provide a rating for the total importance of a scholarly journal, including changes in influence over time. In addition to journal-level metrics, the Eigenfactor website has rankings for the various disciplines, but also some interesting disciplinary mapping tools.
Author H-Index is an author level metric that measures author productivity and the citation impact of an author’s publications. Use Google Scholar Author Search to find an author’s calculated h-index as well as see how many times they have been cited per year. For example, an individual with an h-index of 150 has 150 published papers that have been cited 150 times or more. A higher h-index correlates to higher research impact.
