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?

This might be a bizarre question, but can anyone point to some analysis for a 
large general library, consortium, or even like WorldCat, a distribution of 
materials by class?  So say for example 10% of the collection is in the 700s, 
and half of that is in the 741s, a quarter is in 746.432...
This table:
Table 4: Subject breakdown, nonfiction print books
History and auxiliary sciences

 From http://www.dlib.org/dlib/november09/lavoie/11lavoie.html isn't really 
granular enough.
Thanks!
