Christina, I was hoping that someone with more info would reply, but to 
my knowledge the services that do these statistical surveys are 
"pay-fer" so this might be considered proprietary info. Presumably 
libraries that have used these services received the results, but may 
not be allowed to share them. You might, however, have better luck on a 
list that has a higher percentage of collection development librarians. 
Unfortunately, I don't know what list that would be. Anyone?
