This paper contributes to intellectual discourse on the predictions of information resources availability and accessibility on library use in Lagos State University, Nigeria. This study adopted survey research design of correlation type. The study population is made up of undergraduate students and other library users in the university. A total of two hundred (200) users participated in the study during the study period November, 2014-May, 2015. The instrument for data collection was a semi-structured questionnaire which was validated using Cronbach's alpha coefficient of 0.70 and above. Data analysis was done by means of percentage distribution, correlation and linear regression. The findings revealed a statistically significant positive correlation between information resources availability and use of library (r = 0.433, P< 0.05). We found a strong statistically significant positive correlation between information resources accessibility and use of library (r = 0.668, P< 0.05). Our results indicated a statistically significant positive correlation between information resources accessibility and availability (r = 0.440, P< 0.05). The paper concluded that both information resources availability and accessibility were moderate with special collections being the most available and accessible to library users. We recommended that library materials should be made available and accessible to all users regardless of social class thereby enhancing library patronage in the university.
