After tweaking with VUFind's configuration files, our "sandbox" implementation of the "Catholic Portal" now supports many (if not all) of VUFind's Web 2.0 features -- faceted browse, favorites, cover art, reviews, author blurbs, etc. Please give them a whirl. Create an account for yourself and add some items to your Favorites.
