Availability and timely access to information is indispensable in policy formulation and implementation. It is often believed that a library is as good as its patronage. This study is an attempt to relate the level of patronage of Olabisi Onabanjo University Library by its policymakers to its information delivery capability. A questionnaire was used to gather data, with 102 copies administered at the senate level and 18 copies administered at the Governing Council level. A total of 89 copies were returned, representing an 80 percent response rate. The study reveals inadequate patronage of the library by policymakers. The study concludes that the non-use of the library by a high percentage of these policymakers is inimical to the university library's development plans and information delivery capability as they will always find it difficult to adequately understand the library's challenges. The study recommends a more conducive reading environment, creation of better awareness of library services, better public relations, and marketing strategies to generate goodwill from target users.
