Journal Impact Factor

The Journal Impact Factor (JIF) is a journal-level metric calculated from data indexed in the Web of Science Core

Collection. It should be used with careful attention to the many factors that influence citation rates, such as the volume of publication and citations characteristics of the subject area and type of journal. The Journal Impact Factor can complement expert opinion and informed peer review. In the case of academic evaluation for tenure, it is inappropriate to use a journal-level metric as a proxy measure for individual researchers, institutions, or articles. Learn more

Journal Citation Indicator (JCI) 1.57

 Export

The Journal Citation Indicator (JCI) is the average Category Normalized Citation Impact (CNCI) of citable items

(articles & reviews) published by a journal over a recent three year period. The average JCI in a category is 1.

Journals with a JCI of 1.5 have 50% more citation impact than the average in that category. It may be used

alongside other metrics to help you evaluate journals.

JCR Years

The Citation Distribution shows the frequency with which items published in the year or two years prior were cited in the JCR data year (i.e., the component of the calculation of the JIF). The graph has similar functionality as the JIF Trend graph,

including hover-over data descriptions for each data point, and an interactive legend where each data element's legend can be used as a toggle. You can view Articles, Reviews, or Non-Citable (other) items to the JIF numerator. Learn more

The Eigenfactor Score is a reflection of the density of the network of citations around the journal using 5 years of cited content as cited by the Current Year. It considers both the number of citations and the source of those citations, so that highly cited sources will influence the network more than less cited

sources. The Eigenfactor calculation does not include journal self-

citations. Learn more
