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

8 percent

Engineering and technology

7 percent

Business and economics

7 percent

Language, linguistics, and literature

6 percent

Philosophy and religion

5 percent

Health and medicine

5 percent

Art and architecture

3 percent

Law

3 percent

Sociology

3 percent

Education

3 percent

Other

Unknown

35 percent

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