his study employed a survey method to explore the library use characteristics of undergraduates in a Nigerian University; Ondo State University of Science and Technology (OSUSTECH). The university started academic activities during the 2010/2011 session with four departments and ten academic programmes. Questionnaires were used to gather data from the entire student population, 426 students. 332 undergraduates (78%) completed and returned copies of the questionnaire. Analysis of the returned questionnaires revealed that the respondents make use of the library for few days per week and only for academic purposes. They consult reference sources and subject textbooks which they wanted in both print and electronic formats while their previous knowledge of school library use and library instruction programmes positively influenced the undergraduates’ use of library. The study in conclusion recommended involvement of the undergraduates in collection development activities of the library, acquisition of both electronic and print titles, and current awareness services on library’s acquisition, functions and services.
