This user survey was part of a three-part diagnostic study that sought to obtain information on how public libraries operate in Latin America (Argentina, Colombia, El Salvador, Guatemala, Honduras, Panama, and Venezuela) and the Caribbean (Barbados, Grenada, Jamaica, and Surinam) and the social role performed by this type of service in the region. Each part of the study involved preparation and administration of a questionnaire to public libraries in all countries of the region. A total of 3,796 questionnaires representing 192 libraries in 11 countries were processed. The objectives of the user survey were: (1) to draw a user profile based on sex, age, level of education, background (urban, suburban, or rural) and socio-economic level; (2) to draw a user profile based on use made of the library, taking into account the stated usefulness of the information sought, the type of material consulted, how long the user has been visiting the library, how often and how much, and how well his information needs are satisfied; (3) to investigate the relationship between the user's choice of a library and the features of the library that affect this choice; and (4) to obtain information on how users learn about the library. The first section of this report sets forth the objectives of the user survey, briefly describes the methods used, and characterizes the participants. The second section contains an analysis of the data obtained and presents the conclusions. Questionnaires and statistical tables showing study results are appended. (THC)
