This document outlines requirements for a library management system. It will automate tracking of book details, issues, and returns. The system has two user types - users can check availability and return books, while administrators manage user registration, book entry and issue, and returns. Functional requirements include modules for book entry, user registration, book issue, and return. The system aims to reduce manual work, provide reports, and accurately track book availability in real-time as books are issued or returned.
