The use of the library is inevitable for students’ learning, academic pursuit and self-development. School libraries provide information materials for use by the students as well as the Internet. The study investigated the correlation between Internet use and library patronage among students in selected senior secondary schools in Ojo Local Government Area of Lagos state, Nigeria. The study adopted a survey research design. The findings showed a marginal preference for Internet use as complement to Library patronage. It was further revealed that the Internet use saved time, was more informative, and less expensive with more useful resources. The result showed no significant relationship between Internet use and library patronage. The study concluded that steps must be taken by relevant authorities to encourage library patronage. Therefore, the study recommended the provision of functional school libraries to further promote library patronage and enhance students’ academic achievement.
