Abstract
University library services aim to meet the information needs of the university community, fostering learning and research. Quality service, particularly in tangible aspects and reliability, leads to user satisfaction. Staff attitude significantly impacts library service utilization, as does library policy, which guides library operations. The study adopted survey research design. The study population comprised 80,247 university library users in Ogun State, Nigeria. A sample size of 1,513 was determined using the Krejcie and Morgan (1970) method. Universities were stratified into federal, state, and private categories, and respondents were purposively selected. The findings indicate high-quality service delivery in university libraries in Ogun State, Nigeria, in terms of tangibles (Mean = 3.23, SD = 0.77) and reliability (Mean = 3.20, SD = 0.82). Respondents agreed that staff attitude and library policies were positive (Mean = 2.89, SD = 0.93; Mean = 3.10, SD = 0.88respectively). Staff attitude and library policies significantly influenced service delivery (R2= 0.253, β= 0.503, t = 18.411, p<0.05; R2= 0.322, β= 0.568, t = 21.822, p<0.05, respectively). In conclusion, staff attitude and library policies significantly impact service delivery in university libraries in Ogun State, Nigeria. Recommendations include hiring qualified staff with a user-centric approach, continuous user needs assessment, and fostering a positive disposition. Additionally, staff attitude and library policies should be actively utilized for enhancing library services.
