摘要:The advent of information and communication technologies (ICTs) has greatly revolutionalised the way undergraduates’ access and utilise information resources in academic libraries. Consequently, academic libraries stock their collection with both print and electronic resources. A lot of funds go into the provision of e-library resources in Nigerian universities, e-resources are underutilised by undergraduates. This study set out to investigate the influence of self-efficacy on e-resource utilisation by undergraduates in three Nigerian universities. Questionnaire was the data collection instrument for the study. Three federal universities were selected for the study. Of the 300 copies of questionnaire administered, 261 were duly filled and analysed giving a response rate of 87%. The study revealed that undergraduates in federal universities possessed a high level of self-efficacy. In rank order, the self-efficacy levels of respondents in the selected institutions were, University of Port Harcourt 89(34.1%), University of Ibadan 80(30.7%) and Obafemi Awolowo University 72(27.6%). The study also revealed that undergraduates’ level of e-library resources utilisation was low. The study established a statistically significant relationship between self-efficacy and e-library utilization, a statistically significant difference in e-library utilisation of the undergraduates in the three selected universities. No significant gender difference in e-library resources utilisation of the undergraduates was found. Libraries should embark on aggressive awareness campaign of e-library resources to enhance utilisation.
