Abstract

Eigenfactor.org, a journal evaluation tool that uses aniterative algorithm to weight citations (similar to the PageRankalgorithm used for Google), has been proposed as a more validmethod for calculating the impact of journals. The purpose of thisbrief communication is to investigate whether the principle ofrepeated improvement provides different rankings of journals thandoes a simple unweighted citation count (the method used by theInstitute for Scientific Information@ [ISI]). © 2008 WileyPeriodicals, Inc.
