The above table compares the citation impact of journals in a given field as measured over three different time spans. The left-hand column ranks journals based on their 2007 “impact factor,” as enumerated in the current edition of Journal Citations Report®. The 2007 impact factor is calculated by taking the number of all current citations to source items published in a journal over the previous two years and dividing by the number of articles published in the journal during the same period–in other words, a ratio between citations and recent citable items published. The rankings in the next two columns show impact over longer time spans, based on figures from Journal Performance Indicators. In these columns, total citations to a journal’s published papers are divided by the total number of papers that the journal published, producing a citations-per-paper impact score over a five-year period (middle column) and a 28-year period (right-hand column).

CORRECTION, JULY 7, 2009:

At the time of publication, July 5, 2009, the impact factor year was incorrectly stated in the above text as 2008. It has since been changed to the year 2007.

Using Eigenfactor to Measure Journal Ranking

Eigenfactor is a free tool developed by Carl Bergstrom’s lab at the University of Washington. It measures the impact of a journal based on the number of citations as well as journal pricing. They describe themselves as:

(1) Eigenfactor.orgTM scores and Article InfluenceTM scores rank journals much as Google ranks websites.


(2) Eigenfactor.orgTM reports journal prices as well as citation influence.

(3) Eigenfactor.orgTM contains 115,000 reference items.
Eigenfactor.org not only ranks scholarly journals in the natural and social sciences, but also lists newsprint, PhD theses, popular magazines and more. In so doing, it more fairly values those journals bridging the gap between the social and natural sciences.

(4) Scores adjust for citation differences across disciplines.

(5) Scores rely on 5-year citation data.

(6) Scores are completely free and completely searchable.
