The library patrons’ services system of the Delta State College of Education, Mosogar; is an essential part of the institution’s whole library system. The whole library system comprises the transaction system and the patrons’/user’s services system. Even with an effective transaction aspect, the whole library system will not still be sufficiently resourceful without an efficient patrons’ services aspect which combines to drive the operations of the College library system. The focus of this research work is the conversion of the manual College library patrons’ services system into a computerized system for greater service delivery to the end-users. The challenges with the old patrons’ services system were inaccuracies and delays in the end-users’ registration, borrowing of books, returning of borrowed books, inconsistent details on borrowed/misplaced books with patrons’ and the inappropriately computed charges for borrowers with books exceeding dates-due or that are lost. The computerization of the system is to eliminate the identified challenges and to modernize its services for the overall benefits of the library end-users. The resultant goal is to evolve a system with greater speed, accuracy and security features that will produce a user-friendly interface for staff and students. This is intended to create an easy and efficient access for the system patrons’ and books’ information in the system; capture dates-due and titles of borrowed books for each borrower, generate information on unreturned/lost books and borrowers’ details. It is equally created to generate information on the most and least borrowed books, display the details of available books in the patrons’ system by category, and automatically compute charges for overdue books in the patrons’ accounts respectively.
