The Library is the most important organ in any citadel of learning. It serves as a support, not only to teaching but also to research and developmental activities. The academic health, intellectual vitality, and effectiveness of any institution depend largely upon the state of health and excellence of its library. The library is the engine room and the powerhouse where information is collected, stored, processed, and retrieved for usage. A visit to the library is a journey to discovery. Academic development is seriously dependent on the quality of the Library. In Ajayi Crowther University, we can boast of a Building that is imposing and that, for years to come, will be most suitable and adequate for all forms of expansion that are bound to take place as the University grows in number of academic programmes, staff, and students. Presently our Library can sit 1,500 users conveniently. The book holdings in the Library have also increased from 3,000 in 2007 to over 20,000. The Virtual Library, a critical tool of research in these modern times is an important feature of the T.Y. Danjuma Library. The Library is a big asset to the University and the University will not relent in making it one of the best university libraries in the country in terms of facilities and services. Every User of the Library; be it Student, Staff, Researcher, etc., is expected to register and obtain a pass and an Identity Card which authorize access to library resources and services
