This sounds very promising. The eXtensible Catalog project has received more funding. I love seeing open source library apps moving forward:
A $749,000 grant from the Andrew W. Mellon Foundation to the University’s River Campus Libraries will be used toward building and deploying the eXtensible Catalog (XC), a set of open-source software applications libraries can use to share their collections. The grant money will also be used to support broad adoption of the software by the library community. The grant and additional funding from the University and partner institutions makes up the $2.8 million needed for the project. The resulting system will allow libraries to simplify user access to all library resources, both digital and non-digital.
