Revisions to the Bergstrom and McAfee Graphs

[Phil Davis <pmd8@cornell.edu>]

The initial publication of my report had Lippencott Williams & Wilkins 
titles miscategorized under Springer-Kluwer.  Due to clarification of 
ownership, 102 titles have been removed from the Springer-Kluwer category 
and the data were reanalyzed.  The result of this recategorization had the 
effect of increasing all price indexes for Springer-Kluwer.  Its Price per 
Article increased by $2.18 to $19.03; its Price per Citation increased by 
$2.12 to $9.81; its Composite Price Index increased by $2.60 to $14.00; 
and its Relative Cost Index increased by $0.56 to $4.75

The result of these changes also changed how Springer-Kluwer titles were 
placed into value categories.  The percentage of S-K journals falling into 
the "good" price category decreased from 9% to 2%.  Titles falling into 
the "medium" price category decreased from 18% to 13%.  S-K ournals 
falling into the "bad" category increased from 73% to 84%.

I hope that these data corrections have satisfied Lisa Dittrich and Morna 
Conway.  The main findings of these tables and graphs still hold, and I 
hope that we can move to more constructive conversations on the 
interpretation and meaning of these graphs, instead of calling the data 
irrelevant or the authors, "dodos".
