The study investigated the responses of post graduate students on the extent of utilization and accessibility of library resources as well as level of satisfaction with the quality of services provided in the Federal University of Agriculture, Abeokuta library. A descriptive survey design was used to investigate the study and random sampling technique was used to select the respondents. Questionnaire was used to gather information from PG students in all the ten faculties in the university. Out of 100 copies of questionnaire administered, 86 were returned and found usable for the analysis. The result revealed that collections of the library are adequate in term of resources; Books and Newspapers are highly accessible but Newspapers are not utilized by the PG students. Electronic journals were highly utilized by the PG students. The study also revealed that students were mostly using personal modem for internet service. On the level of satisfaction with the service quality; students were not satisfied with the Accessibility to electronic databases, and the way information needs of users are being met. Also the students were not satisfied with the Provision of timeliness and promptness of information to users and lastly with the way information are being disseminated to users.
