Abstract: Library automation has to do with the act of computerizing user’s registration and library materials, borrowing and returning, locating of material and calculating overdue fines in the library system. The status of automated library management systems in Nigerian state universities were assessed through site visits and interview surveys of the views of academic/non-academic staff, students and researchers in the universities. This study designed an automated library system that will help university libraries to keep accurate track of the transaction done via storing information about library users, accurately locating library materials effectively with ease and tracking of all borrowing and returning of books. Also where fine is applicable, the system can calculate overdue of library defaulters and provide useful information that can help the management of the library in decision making. The findings were used to design an automated library management system for Delta State University in Nigeria.
