An investigation was made of the Nashville Union Catalog to explore the possibility of its expansion into a regional catalog and making it the nucleus of a bibliographic center serving the state of Tennessee. The primary objectives were investigation of: the catalog and its format possibilities; the structural organization, and required funding, for an operation involving many libraries of different types; access to the union catalog, and service from it. Among the recommendations were: continuation of the present card form, expansion to include cataloged items of all types of libraries, submission of funding requests to likely sources for computerization of acquisitions, expansion of the operation into a bibliographic center with initial service to local libraries but with a view of expanding state-wide, and that the Tennessee State Library should consider the project for funding.
