This study contains an inventory of Indiana's present library facilities together with projections of the need for future library resources based on the population projections. To facilitate presentation and analysis of the data in this report, 14 state planning regions were used. The relevant geographic regions section defines Indiana's economic regions, discusses administering Indiana's libraries on a regional basis, and the feasible regions for public libraries in Indiana. This is followed by a discussion of the library and information services now available in Indiana's public, school, institutional and business libraries. A look at the future demand for library services precedes the equating of present and future demand for library services. Appendix B states the equation used to predict future circulation. (NH)
