This pamphlet presents methods by which a library may survey its community to determine local information needs, especially those of disadvantaged adults. Data may be collected from public agencies or from community residents, by telephone, interview or questionnaire. All of these procedures are discussed in terms of advantages, methods, and cost/benefit. Sample questionnaires for agency heads and for community residents are provided, as are lists of those agencies, such as state offices, school districts, and local businesses, which may have already compiled some of the data needed by the library. Finally, a chart organizes the specific data needed, with its possible source, and provides a space for local statistics. (SL)
