Evaluating News & Internet Sources

Evaluating information sources can be a difficult and complicated process. The resources below may serve as guides as you build up your own strategies for determining what sources are trustworthy, valid, and factual.

Evaluating Scholarly Sources

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.
