Thomson Reuters/ISI has released its 2008 Science Edition of the Journal Citation Reports, which gives journal Impact Factors and rankings of approximately 8,000 science journals. The 2008 Impact Factors of the journals of the APS, along with a comparison of the past 3 years, are given in the table below. The table also shows the rank of APS journals in the physiology category, as well as each journal's cited half-life.

The 2008 Journal Citation Reports includes an update to the Five-Year Impact Factor and Eigenfactor™ Metrics in JCR Web. Eigenfactor™ Metrics use citing journal data from the entire JCR file. The Eigenfactor™ score and the Article Influence™ score are calculated based on the citations received over a five-year period.
