- http://www.eigenfactor.org/about.php Eigenfactor® scores and Article Influence® scores rank journals much as Google ranks websites. Scholarly references join journals together in a vast network of citations. Our algorithms use the structure of the entire network (instead of purely local citation information) to evaluate the importance of each journal. Eigenfactor.org reports journal prices as well as citation influence. In collaboration with journalprices.com, Eigenfactor.org provides information about price and value for thousands of scholarly periodicals. While the Eigenfactor Scores and Article Influence Scores do not incorporate price information directly, the Cost-Effectiveness Search orders journals by a measure of the value per dollar that they provide. Eigenfactor® scores and Article Influence® scores adjust for citation differences across disciplines. Different disciplines have different standards for citation and different time scales on which citations occur. The average article in a leading cell biology journal might receive 10-30 citations within two years; the average article in leading mathematics journal would do very well to receive 2 citations over the same period. By using the whole citation network, our algorithm automatically accounts for these differences and allows better comparison across research areas. Eigenfactor® scores and Article Influence® scores rely on 5-year citation data. In many research areas, articles are not frequently cited until several years after publication. Therefore, measures that only look at citations in the first two years after publication can be misleading. The Eigenfactor score and the Article Influence score is calculated based on the citations received over a five year period.
