The research investigated study behaviour and information literacy skills as predictors of library information resources usage among the
undergraduates. The survey method was adopted for the study. Structured questionnaire was employed for data collection, while three research
questions were answered and one hypothesis was treated. The population of the study was the undergraduate students in two selected public universities in South-west, Nigeria. Multi-stage sampling technique was adopted to select a sample of 435 undergraduate students. The data collection instrument was the questionnaire. The data collected were analysed using frequency counts and percentages, while Pearson product moment correlation was used to test the hypothesis. Findings showed that majority of the respondents held positive study behaviour and their level of information literacy skills was high. The study recommended the need for emphasis on positive study behaviour among undergraduate students, and provision of enough funds by the university management for libraries to acquire recent and up-to-date information resources.
