Eric Lease Morgan took a A Trip to Rochester to Learn about XC. He had the opportunity to visit the University of Rochester River Campus and meet with a number of very smart people to discuss a thing called XC (eXtensible Catalog, extensiblecatalog.info). This travel log documents the experience.
Communities and cooperation are a large part of what it means to be libraries. If libraries were to pool their resources and work together, I am certain the sum will be greater than its parts. XC is a manifestation of this idea.
