This study was conducted on students' perceived effectiveness in the use of library resources in some selected Nigerian Universities. Questionnaire was the main instrument for collecting data. 600 copies of questionnaires were distributed, 530 were returned. The overall response was 88.3%. The responses showed that, majority of the users source their information through the catalogue indexes. While those not satisfied in their quest for information attributed them to lack of physical materials and the cumbersome library organization. Some recommendations were made for improvement, such as the role of e-library and its application, orderliness, relevance of resources and user education through orientation.
