The study investigates infrastructural resource provision in university libraries in Nigeria’s North Central Zone with reference to managerial variable of planning as influence factor via an Ex post facto research. The Cronbach Alpha method was used to determine the internal consistency of the items of the instrument. Data were collected by means of a questionnaire complemented by observation of infrastructural resources and interview of university librarians. From the 124 copies of questionnaire distributed 109 (76.76%) copies were returned. Data collected were analyzed by use of mean, standard deviation Pearson’s Product Moment Correlation Coefficient (PPMC). The method of testing the hypothesis was by means of Multiple Regression Analysis in which the Statistical Package for the Social Science (SSPS) was employed at 005 level of significance. The study found that infrastructural resources were provided to a large extent and planning was found to have a significant influence on the provision of infrastructural resources in the university libraries. The study consequently recommended that in order for Nigerian University Libraries to ensure even provision of adequate infrastructural early and effective planning should be implemented.
