Steve,
I don't know if this data is of interest to you since it does not come from
a library catalog in a traditional understanding, and since the database is
collection- rather than item-centric but...
Analysis of the web log of Digital Collections and Content (
http://imlsdcc.grainger.uiuc.edu/) aggregation of 202 digital collections
shows the following distribution of facet use:
1. collection-level browsing:
collection title - 45%
subject - 25%
place - 17%
types of objects in collections - 13%
2. item-level search:
keyword- 42%
title and/or subject-30%
author-28%
3. the only collection-level search option provided is by keyword, with a
possibility to limit results by types of objects. The object facet was used
for limiting results in 7.4% of collection-level searches.
