2009 Journal Citation Report Released

ISI has released the 2009 edition of the Journal Citation Report. Ranking journals by the traditional two year impact factor:

The first thing I notice is how impact factors have been increasing rapidly in recent years. At least the top journals are getting considerably more citations to their articles. Also, REEP, JEEM, and Ecological Economics are all in the top 20 journals by this measure. In a slow publishing field like economics the five-year impact factor probably makes more sense:

This list is a bit more consistent with conventional notions of prestigious journals in economics.
REEP still does well by this measure. The eigenfactor score and article influence score take into account where articles are cited:

None of the environmental journals make the top twenty now. Environmental economics articles get cited a lot but not in journals that themselves are highly cited.
