The major objectives of this study of adult information needs in Indiana were: (1) to gain some understanding of present and future needs of the business and industry, agriculture and labor sectors of Indiana's economy, (2) to determine and evaluate how these sectors now meet information needs and (3) to explore the information-acquiring habits of the general public, their willingness to pay for library services, and their opinions of present services and changes which could be made. The conclusions of the study, which can serve as a model for public libraries throughout Indiana, indicate that the public library has little relevance to the information needs of the adult population. The well-educated housewife is the major user, few men make use of the library and the library is not meeting the self-education or reference functions set as its major reason for existence. New approaches and operating techniques must be tried or the public library will become an extension of the public schools or a publicly subsidized recreational service for the well-educated housewife.
