Re: 2006 Elsevier Impact Factors- the really relevant statistics

[David Goodman <dgoodman@princeton.edu>]

And presumably 35% of Elsevier titles declined in impact factor.

But since impact factor is not relative--the impact factor of 
journals in general will increase if the citation density 
increases overall--it would be more interesting to see which 
titles increased in rank within their categories, and which ones 
declined.
