Utilizing 1970 census data and updates plus local data and library records, the study seeks to assess the current status of public library usage in and around Aberdeen, South Dakota. A demographic profile of the community as a whole was first constructed and then compared with similar data for known public library users. Information was also gathered as to what types of library materials were being used, the age of the collection, library financial support, and governance. The resulting analysis yielded implications for more responsive library services in a number of areas. Among these are a more equitable city/council public library relationship, an expansion of the paperback book collection and audiovisual services, and the development of elementary school libraries to replace the current bookmobile service.
