This study is an assessement of the Kwara State Public Library Services, Problems and Prospects. A survey research was used for the study. The study employed documented sources and questionnaire as an instrument in collecting data. The data collected from the study were subjected to descriptive data analysis in a tabular form and percentages. Findings revealed that public library services in the State, such as current awareness services, readers’ advisory services, reference services, mobile library services, user education, among others can enhance effective and efficient service delivery. Results  obtained showed that 60% of the library users were not satisfied with the services provided by the Kwara State Public Library while 30% indicated that awareness was not created on the different services rendered in the Library. The results further indicated that the services of the Public Library were not satisfactory to the community of users as a result of lack of adequate infrastructure, trained and qualified staff, inadequate funds, and location of the Library. Hence, the study recommends the provision of adequate funds, recruitment of qualified and competent staff, training and re-training of existing staff, creation of public awareness about library services for users, and automation of the library resources for effective and efficient service delivery.
