The study focused on users' satisfaction with library services at the Delta State University main Library, Abraka, Delta State. The objective was to find out if users are satisfied with the services, facilities, the library environment, information sources and staff of the library. Using the descriptive survey design, the population for the study consisted of all registered library users in the Site II of the Delta State University, Abraka Campus. The study employed the simple random sampling techniques in selecting the sample size for the study, and with a questionnaire data were collected. The findings revealed that the services offered at the Delta State University are inadequate and below average. Most users were satisfied with the availability of information sources in the library but also registered that most of these information sources are not available for loan. The findings also showed that there is a significant relationship between the assessment of library collection by users and their satisfaction with information sources. The library environment is clean and the reading carrels are adequate, but there are no effective lighting and toilet facilities.
