This study investigated the influence of training and development on employee performance in selected university libraries in South-West, Nigeria. The survey research design was adopted for this research work. A structured questionnaire was used as an instrument of data collection. The total enumeration technique was employed, and out of the total copies of the questionnaires administered, 103 were completed and returned. Frequency distribution and percentages were used for analysis, while the hypotheses were tested using correlation and regression analysis tools of the Statistical Package for Social Sciences (SPSS). The result of the study showed a significant correlation between staff training and development and employee performance in university libraries in Nigeria. The result of this research also showed that staff training and development significantly influence the performance of library staff in selected university libraries. The study, therefore, recommends that university libraries management should regularly organize training and developmental programs for their employees. Furthermore, the research suggests that library employees should be encouraged to participate in training organize within and outside their institutions, as this would ensure increased performance/productivity.
