2009 Plant & insect science journal impact factors released

Thomson Reuters has just published the 2009 Journal Citation Reports (JCR), available by online subscription to UW-Madison library users. These metrics, including the "impact factor," can be used to compare journal performance. JCR compares 9,100+ peer-reviewed journals from 2,200 publishers in 78 countries.

New features:
  • 1,055+ journals with their first published impact factor
  • Updated 5-year impact factors and Eigenfactor metrics
  • "Rank in category" for each journal's subject area, along with a box plot of impact factor distribution for all journals in that category
  • Journal "self-citations" and analysis of their effect on impact factor
