The study investigated the influence of knowledge on the use of online public access catalogue and utilization of library resources by undergraduate students in federal universities in South-South Zone of Nigeria. The population of the study comprised 952 registered library users from three selected universities in the study area during 2017/2018 academic session. Questionnaire was the main instrument for data collection. The data collected was analyzed using Mean and Standard Deviation. The hypothesis was tested using simple linear regression and multiple regression analyses respectively. The regression model produced a regression coefficient of R=.431, which revealed that there is a strong positive relationship between knowledge on the use of Online Public Access Catalogue (OPAC) and utilization of library resources. The findings further revealed that knowledge on the use of OPAC is relatively low in the universities studied. It was recommended that library program currently being taught in Nigerian universities should be reviewed and taken into cognizance the important of information literacy skills required by students to enhance them access print/digital content of the library.
