I read on another thread that Cooley used factors like the square footage of their library to come up with their rankings. I thought it was a bit of sarcasm. It wasn't. Some of the factors they consider (not sure how it's all weighted):
Total Volumes in Library
Total Titles in Library
Total Serial Subscriptions
Total of Professional Librarians
Library Hours per Week with Professional Staff
Total Library Hours per Week
Library Seating Capacity
Number of Networked Computers Available for Use by Students
Library Total Square Footage
I'm disappointed in Cooley's lack of inventiveness. If they considered the number of janitors employed in library clean up, or the total surface area of desk-top space available to use for study... or SOMETHING, I'm sure they could have placed themselves above Harvard and the like.
