University use of faceted navigation

All,

Is anyone out there aware of any universities currently using 
metadata-generated, faceted navigation on their website? It would be 
especially useful if it was a library site. If so, could you please send me 
their URL? If you were involved in implementing such a site, I'd love to 
hear about what metadata standard you used and other such details. I think 
the Forrester site is the first one I've seen that actually implements 
faceted navigation and would love to see more real-world examples, even if 
they're corporate.

Thanks!
