Moving Forward is a blog I discovered via alls things cataloged.
From the Forward blog:
Forward is a Resource Discovery experiment that builds a unified search interface for library data.
Today Forward is 100% of the UW System Library catalogs and two UW digital collections. The project also experiments with additional search contextualization by using web service APIs.
Forward can be accessed at the URL:
http://forward.library.wisconsin.edu/.
Sounds like a great opportunity for topic map fans with an interest in library interfaces to make a contribution.
