This UML use case diagram for library management illustrates the dialogue between two main actors: faculty and students. Both users interact with the login, search the catalog, borrow and return books, reserve publications, renew loans, and download e-books use cases. The payment of late fees is also allowed for students. The UML use case diagram explains how digital library systems can facilitate users with online book access and self-service features. This faculty and student library management system facilitates effective resource access, brings educational institutions into the modern age, and streamlines library processes.
