The Louisiana Online University Information System is a network that connects twenty-one academic libraries, sixty-six public libraries, the State Library of Louisiana, and eighteen K-12 school libraries. Network traffic currently is growing 30 percent annually. This analysis examines interinstitutional use of the network among fourteen of the connected academic libraries to determine ifa correlation exists between overall network relevance and the degree to which a library's online catalog is searched from an external point. Such a study provides useful information for both network and library administrators as they plan resource allocation, online service provision, and other related network enhancements.
