This document describes a digital library system project that was developed to make a library more user-friendly and efficient. The project uses a desktop application built with Java, SQLite database, and Windows OS. It allows users to search for books, check availability, view book details, and request new books. It also has an admin module for managing books, members, issue logs, and requests. The project aims to reduce the time taken to find books and workload for library staff compared to the existing manual system. It could be expanded in the future to integrate more library processes.

7. EXISTING SYSTEM
 Any information regarding a book, its availability or cost has to
be gained from the librarian.
 Users have to browse the library manually to find a book with
required content.
 No provision for the users to request new books.
 In short the existing system has a lot of disadvantages.
 Limited knowledge.
 Less interaction.
 Time consuming.
