Re: Which facets are most used?

Greetings from Florida.  FCLA is running Endeca with our own front end
web application (we call it Mango) for 11 State University Libraries.
NCSU got us started on this project over a year ago.  All 11
institutions are using Mango as their library catalog.

Here's a snapshot of usage statistics for one Institution for one month
(University of Florida for March 2008):
