Journal Ranking
Eigen Factor
A searchable database of Eigenfactor® and Article
Influence® scores from 1997 to 2015.

We launched the Eigenfactor project in January 2007 in order to provide the scientific community with what we believe to be a better method of evaluating the influence of scholarly journals. The Eigenfactor.org website provided a searchable database of Eigenfactor scores and Article Influence scores for the numerous journals covered in Thomson-Reuters Journal Citation Reports. Years later, the scope of the Eigenfactor Project has expanded considerably, but the disseminating the Eigenfactor metrics remain a core part of the mission. Our Journal Ranking tool provides a web interface through which researchers, librarians, and other interested parties can rank journals by field and track changes in influence over time.
