Training and retraining of library staff by the academic library, policy revision and foundation and revision of the policies be vested in faculty representative student representative and CD librarians. The researcher however recommended that librarians should insist on having functional policies to achieve standard library collections, materials should be ordered for the library continuously without necessarily waiting for a particular time, efforts should be made by library school to include management and budgeting courses for student’s librarian as this will help in the understanding of policies in administration. The Nigerian Library Association (NLA) should create a standard policy for academic libraries on their material collection development and ensure compliance by all academic libraries for them to be of a standard and enjoy increased funding. The library management should strive to engage its staff in participating in workshops and seminars particularly, on methods of improving collection development policy by doing so, their libraries collections would meet the needs of the users, and the parent institution should allocate enough funds for the procurement of the library materials and equipment which will be beneficial to the students, lecturers and future researchers.
