EigenFactor Information

Category: Journal Level


Definition: The EigenFactor Score attempts to calculate a percentage estimate of the total time that all journal users spend with that journal compared to all other journals. The numbers are normalized, so that the total of all Eigenfactors is 100. 


Location: Eigenfactor.org and on the Journal Citation Report (Web of Science)


Field Normalized? No


Caveats: Inconsistent when you compare it on Eigenfactor.org to the Journal Citation Report.


Sample Statement: A significant number (136) of Dr. Fauci's work that are indexed in Journal Citation Reports are published in the Journal of Immunology, which had an EigenFactor Score of 0.04681 in 2022.

What that means: The Journal of Immunology has 0.046% of the total influence of all indexed journals in Journal Citation Reports. (In comparison, Nature has the highest at 1.100%).
